1.5 COPY PROCESS 1 B070D872.WMF 2 10 3 4 9 5 8 7 6 B070D873.WMF 1. EXPOSURE A xenon lamp exposes the original. Light reflected from the original passes to the CCD, where it is converted into an analog data signal. This data is converted to a digital signal, processed, and stored in the memory. At the time of printing, the data is retrieved and sent to the laser diode. For multi-copy runs, the original is scanned once only and stored to the hard disk. 2.
3. LASER EXPOSURE The processed data from the scanned original is retrieved from the hard disk and transferred to the drum by four laser beams, which form an electrostatic latent image on the drum surface. The amount of charge remaining as a latent image on the drum depends on the laser beam intensity, which is controlled by the laser diode board (LDB). 4. DRUM POTENTIAL SENSOR The drum potential sensor detects the electric potential on the drum to correct various process control elements. 5.
SECTION 2 DETAILED DESCRIPTIONS
2. DETAILED SECTION DESCRIPTIONS 2.1 DOCUMENT FEEDER 2.1.1 PICK-UP ROLLER RELEASE [F] [E] [B] [C] [A] [D] B070D916.WMF When the original set sensor is off (no original on the original tray), the pick-up roller stays in the up position. When the original set sensor turns on (or when the trailing edge of a page passes the entrance sensor while pages remain on the original tray), the pick-up motor [A] turns on. The cam [B] rotates away from the pick-up roller release lever [C].
2.1.2 BOTTOM PLATE LIFT [F] [E] [B] [A] [D] [C] [B] [F] B070D917.WMF When an original is placed on the original tray, the original set sensor [A] turns on, the pick-up roller [B] drops on to the original, and the bottom plate position sensor [C] turns off. Then the bottom plate motor [D] turns on and lifts the bottom plate [E] by raising the lift lever [F] until the bottom plate position sensor turns on.
2.1.3 PICK-UP AND SEPARATION [D] [A] [B] [E] [C] [A] [B] B070D918.WMF [C] B070D919.WMF The original separation system is a Feed and Reverse Roller (FRR) system. The pickup roller [A], feed belt [B], and separation roller [C] are driven by the feed-in motor [D]. To drive this mechanism, the feed-in motor [D] and feed-in clutch [E] turn on.
2.1.4 ORIGINAL FEED [D] [B] [A] [C] B070D920.WMF When the leading edge of the original turns the entrance sensor [A] on, the feed-in clutch [B] turns off and the drive for the feed belt is released. The original is fed by the transport rollers [C]. At the same time, the pick-up motor starts again and the pick-up roller [D] is lifted up. When the pick-up roller HP sensor turns on, the pick-up motor stops (see Pick-up Roller Release).
2.1.5 ORIGINAL SIZE DETECTION [B] [C] [G] [D] [F] [A] [E] The ADF detects the original size by combining the readings of original length sensor [A], and original width sensors-1 [B], -2 [C], and -3 [D]. Original Length The original length sensor and the disk [E] (connected to the transport roller) generate a pulse signal. The CPU counts pulses, starting when the leading edge of the original turns on the registration sensor [F], until the trailing edge of the original turns off the entrance sensor [G].
2.1.6 ORIGINAL TRANSPORT [B] [A] [C] B070D923.WMF [E] [D] 3.5 mm B070D924.WMF The transport belt [A] is driven by the transport belt motor [B]. The transport belt motor starts when the copier sends an original feed-in signal. The pressure rollers inside the transport belt maintain the correct pressure between belt and original. The pressure roller [C] closest to the left original scale is made of rubber for the stronger pressure needed for thick originals. The other rollers are sponge rollers.
2.1.7 ORIGINAL SKEW CORRECTION [A] 7 mm B070D925.WMF [B] The transport belt motor remains energized to carry the original to the right about 7 mm past the left scale [A]. Then the motor stops and reverses to feed the original 12 mm to the left against the left scale to correct skew. This forces the original to hit the left scale, which aligns the trailing edge to minimize original skew on the exposure glass. If thin original mode is selected, the original is not forced back against the left scale.
2.1.8 ORIGINAL INVERSION AND FEED-OUT General Operation [A] B070D926.WMF When the scanner reaches the return position, the copier CPU sends the feed-out signal to the ADF. When the ADF receives the feed-out signal, the transport belt motor and feed-out motor [A] turn on. The original is then fed out to the exit tray or fed back to the exposure glass after reversing in the inverter section. This ADF has two exit trays.
Original Inversion [F] [B] [E] [G] [D] [A] [C] B070D927.WMF When the ADF receives the original invert signal from the copier, the transport belt motor, feed-out motor, exit gate solenoid [A], and inverter gate solenoid [B] turn on and the original is fed back to the exposure glass through the inverter roller [C], exit gate [D], inverter guide roller [E], inverter gate [F], and inverter roller.
Original Exit (Single-Sided Original Mode) [B] [A] [C] B070D928.WMF The exit gate solenoid [A] remains off, the exit gate [B] remains closed, and the original is fed out to the right exit tray. The speed of the motor is reduced about 30 mm from the trailing edge of the original to ensure the originals stack neatly on the exit tray. This timing is determined by the length of the original, and the time since the exit sensor [C] detected the leading edge.
Original Exit (Double-Sided Original Mode) [C] [E] [A] [B] [D] B070D929.WMF The exit gate solenoid [A] turns on and the exit gate [B] opens. The inverter gate solenoid [C] remains off, and the original is fed out to the upper tray. The transport belt motor turns off when the trailing edge of the original passes the exit sensor [D]. To stack the originals neatly on the upper tray, the feed-out motor speed is reduced shortly after the trailing edge of the original turns off the inverter sensor [E].

2.2.2 SCANNER DRIVE [C] [D] [E] [B] [A] [F] [G] B070D003.WMF The scanner motor is a dc servo motor. The 1st and 2nd scanners [A, B] are driven by the scanner motor [C] through the timing belt [D], scanner drive pulley [E], scanner drive shaft [F], and two scanner wires [G]. The MCU (Motor Control Unit) board controls the scanner motor. The exposure lamp scans a sheet with 100% magnification at 515 mm/s and returns to the scan position for the next scan at 2500 mm/s.
2.2.3 ORIGINAL SIZE DETECTION [F] [G] [A] B070D052.WMF [B] [C] [D] [E] B070D535.WMF There are three reflective sensors at three locations in the optics cavity for original size detection. The original width sensor [A] detects the original width, and the original length sensor 1 [B] and original length sensor 2 [C] detect the original length. These are the APS (Auto Paper Select) sensors.

2.4.2 LASER EXPOSURE MECHANISM [D] [A] [B] [C] B070D102.WMF The LD unit consists of two 4-channel LDA’s (Laser Diode Arrays) and two collimating lenses. Each LDA produces 4 beams [A]. Each collimating lens [B] is a fixed lens, seated in a V-groove and held in place by a spring and a screw. Four beams from each LDA [C] pass through the collimating lenses, though the apertures [D], then strike the polygonal mirror.

2.4.4 MULTI-BEAM LINE EXPOSURE [A] B070D212.WMF The LD unit contains two laser diode arrays (LDA) [A], each with one 4-channel array, allowing the LD unit to produce a total of eight beams. This multi-beam exposure mechanism has the following advantages: • Reduces the number of rotations required of the polygon mirror motor. • Reduces the amount of noise generated by the polygon mirror motor because it is rotating at lower speed. • Reduces the need for LD unit replacement.
2.4.5 POLYGON MIRROR MOTOR The polygon mirror reflects the laser beam onto the OPC drum to expose the image line by line in the main scan direction. The polygon mirror motor rotates at a constant speed, even while the copier is in standby mode, but shuts off when the copier enters the energy conservation mode. The polygon mirror motor has no brake mechanism, so it requires about 3 minutes to stop rotating.

This machine can produce an image at 1200 dpi by writing each dot twice, possibly with two different values, depending on the results of image processing.
2.4.7 OPTICAL PATH [D] [C] [B] [E] [A] [F] [G] [H] [I] [J] [K] B070D101.WMF The output path from the laser diode to the drum is shown above. The LD unit [A] outputs eight laser beams to the polygonal mirror [B] (six mirror surfaces) through the cylindrical lens [C] and the 1st mirror [D]. Each surface of the polygon mirror reflects eight full main scan lines. The laser beams go to the F-theta lens 1 [E], F-theta lens 2 [F], BTL (barrel toroidal lens) [G], and mirror [H].
2.5 DRUM UNIT 2.5.1 PROCESS CONTROL Drum potential gradually changes for the following reasons: • Dirty optics, exposure glass • Dirty charge corona casing, grid plate • Deterioration of drum sensitivity What Happens at Power On Here is a description of what happens while the fusing temperature is below 100°C immediately after the main power switch is switched on (process control must also be enabled with SP3901 001, or this will not happen).
2.5.2 DRUM UNIT COMPONENTS 8 9 1 7 2 6 5 B070D865.WMF 4 3 The drum unit consists of the components shown in the above illustration. An organic photoconductor drum (diameter: 100 mm) is used for this model. 1. 2. 3. 4. 5. PTM OPC Drum Drum Potential Sensor Pick-off Pawl Image Density Sensor Toner Collection Coil 6. 7. 8. 9.
2.5.3 DRUM DRIVE [C] [A] [B] [D] B070D202.WMF The drive from the drum motor [A] is transmitted to the drum and the cleaning unit through timing belts, gears, the drum drive shaft [B], and the cleaning unit coupling [C]. The drum motor has a drive controller, which outputs a motor lock signal when the rotation speed is out of the specified range. The drum speed for the B070 (90 cpm) is 450 mm/s and for the B071 (105 cpm) 500 mm/s.
2.5.4 DRUM CHARGE Overview [A] B070D203.WMF This copier uses a double corona wire Scorotron system to charge the drum. Because of the high speed of this copier, two corona wires are needed to give a sufficient, uniform negative charge to the drum surface. The stainless steel grid plate makes the corona charge uniform and controls the amount of negative charge on the drum surface by applying a negative voltage to the grid.
Charge Corona Wire Cleaning [D] [A] [A] [B] [C] B070D558.WMF Air flowing around the charge corona wire may deposit toner particles on the corona wires. These particles may interfere with charging and cause low density bands on copies. The wire cleaner pads [A] automatically clean the wires to prevent such a problem. The wire cleaner is driven by a dc motor [B]. Normally the wire cleaner [C] is at the front end (the home position).
2.5.5 DRUM CLEANING Overview [C] [A] [B] [A] [A] [D] B070D866.WMF [B] [E] [B] B070D867.WMF This copier uses a counter blade system to clean the drum. In a counter blade system, the drum cleaning blade [A] is angled against drum rotation. The counter blade system has the following advantages: • Less wearing of the cleaning blade edge • High cleaning efficiency Due to the high efficiency of this cleaning system, the pre-cleaning corona and cleaning bias are not used for this copier.
2.5.6 CLEANING UNIT DRIVE [B] [A] [D] [C] B070D206.WMF Drive from the drum motor is transmitted to the cleaning unit drive gear via the timing belt [A] and the cleaning unit coupling [B]. This coupling drives the cleaning brush [C] directly. The cleaning brush then transmits the drive to the gear at the front, which drives the toner collection coil gear [D].
Cleaning Blade Pressure and Side-to-Side Movement [C] [D] [B] [A] B070D868.WMF The spring [A] always pushes the cleaning blade against the drum. The cleaning blade pressure can be manually released by pushing up the release lever [B]. To prevent cleaning blade deformation during transportation, the release lever must be locked in the pressure release (upper) position. The guide roller [C] at the rear end of the cleaning blade holder touches the cam gear [D], which moves the blade from side to side.
2.5.7 OTHERS Air Flow Around the Drum [E] [G [B] [C] [A] B070D208.WMF [D] [F] The drum cooling fan [A] draws cool air through the filter [B] and sends it to the center of the drum [C], then over the charge corona unit [D]. Holes in the flanges on both ends of the drum allow air to pass through the drum to cool it.
Drum Pick-off Pawls [A] [B] [C] B070D559.WMF [D] If the paper does not separate from the drum after image transfer, the drum pick-off pawls strip the paper from the drum. Pressure from small springs [A] press the pick-off pawls [B] against the surface of the drum. The shaft [C] and the cam [D] move the pick-off pawls from side to side to ensure that they never remain at the same location (this prevents wear on the drum).
Drum Quenching [A] B070D209.WMF In preparation for the next copy cycle, light from the quenching lamp [A] neutralizes any charge remaining on the drum. The quenching lamp consists of an array of 16 red LEDs extending across the full width of the drum.

2.6.2 DEVELOPMENT MECHANISM [E] [F] [G] [C] [H] [A] [D] B070D303.WMF Toner and developer are mixed in the toner agitator[B] by the cross-mixing roller [A]. The paddle roller [B] picks up the developer and sends it to the upper development roller [C]. Internal permanent magnets in the development rollers attract the developer to the development roller sleeve. Developer from the upper development roller sleeve is also attracted to the lower development roller [D].
2.6.3 DRIVE [C] [D] [F] [B] [E] [A] B070D304.WMF The gears in the development unit are driven by the development drive gear [A] when the development motor [B] (a dc servomotor) turns. The gears in the toner hopper are driven by the toner supply roller drive gear [C] when the toner supply roller clutch [D] activates. A one-way clutch on the paddle roller knob [F] prevents counter-clockwise rotation of the paddle roller.
2.6.4 CROSSMIXING [C] [B] [E] [F] [A] [D] [C] B070D303.WMF [E] [B] [F] [A] [D] B070D571.WMF This copier uses a standard cross-mixing mechanism to keep the toner and developer evenly mixed. It also helps agitate the developer to prevent developer clumps from forming and helps create the triboelectric charge. The developer on the turning development rollers [A] is split into two parts by the doctor blade [B].
2.6.5 DEVELOPMENT BIAS [A] [B] [C] [D] B070D305.WMF The CBG (Charge Bias Grid) power pack [A] applies the negative development bias (550V) to both the lower sleeve roller and upper sleeve roller through the receptacles [B] and the sleeve roller shafts [C]. The development bias prevents toner from being attracted to the non-image areas on the drum where there is residual voltage. In addition, the development bias changes with the image density setting chosen for the copy job by the user.
2.7 TONER SUPPLY AND RECYCLING [G] 2.7.1 OVERVIEW [C] [F] [B] [E] [A] [D] Toner is supplied from a toner bank [A] on the left side of the machine and separated from the development unit. The toner bank holds two bottles, but only one bottle operates at a time. A toner bottle motor turns the bottle [B], causing toner to leave the bottle and drop into the toner entrance tank [C]. The toner transport coil in the toner transport tube [D] transports toner to the toner supply cylinder [E].
2.7.2 TONER BANK Toner Bottle Switching Mechanism [D] [C] [B] [A] [E] B070D901.WMF When the upper toner bottle [A] is supplying toner, the upper bottle cap motor [B] pulls out the toner bottle cap. The upper bottle cap sensor [C] detects the actuator [D] of the toner bottle opening rod, then the motor shuts off to close the cap again.
Toner Near-end, Toner End, Bottle Replacement [B] [A] B070D911.WMF [D] [C] B070D909.WMF Each toner bottle [A] has an independent toner bottle motor [B]. An empty toner bottle can be replaced during printing. The toner near-end sensor detects toner as it falls from the toner bottle into the toner entrance tank [C]. If the toner near end sensor [D] detects that no toner has come out of the toner bottle, the toner bottle enters the toner near-end condition.
Meanwhile, the machine indicates that the first bottle is empty. When the user takes out the old bottle, and puts in a new one, this is detected by the toner bottle sensor. ( ”Toner Bottle Sensors”,2-57) However, this bottle is not tested until the second bottle is empty. NOTE: If an empty bottle is not replaced, and the other bottle becomes empty (no toner detected 10 consecutive times, as described above), 200 more copies can be made.
Toner Bottle Sensors [A] [C] B070D912.WMF [D] [B] B070D913.WMF [E] [F] B070D914.WMF When placing a toner bottle in the toner bank, the toner bottle pushes the lock arm [A] downwards. Then the lock arm catches the toner bottle and also pushes down lever [B]. This causes toner bottle sensor [C] to detect that a bottle has been installed (the actuator leaves the toner bottle sensor while the bottle is being inserted in the holder).
2.7.3 SUPPLYING TONER TO THE DEVELOPMENT UNIT [H] [B] [I] [A] [G] [D] [F] B070D902.WMF [C] [E] B070D906.WMF The toner bottle motor turns the toner bottle [A], causing toner to leave the bottle and drop into the toner entrance tank [B]. NOTE: Recycled toner in the tube from the drum cleaning unit also enters the toner entrance tank, and is mixed with fresh toner from the toner bottle. The toner transport coil [C] in the toner transport tube transports toner to the toner supply cylinder [D].
If the toner hopper sensor (in the toner hopper - Toner Hopper) detects an insufficient amount of toner in the hopper, the toner bank mechanism is started up. If there is sufficient toner in the toner entrance tank (detected by the toner near end sensor in the toner bank), the toner supply coil clutch turns on for 2 seconds. The toner supply pump motor turns on for 7 seconds at the same time as the toner supply coil clutch.
2.7.4 TONER HOPPER Toner Supply [G] [C] [E] [A] [F] [B] [D] [G] [F] A294D306.WMF When the toner supply roller clutch [A] (inside the development motor unit [B]) turns on, the agitator [C] mixes the toner transported by the air tube [G] from the toner bank (the toner from the toner bank is new toner mixed with recycled toner). Then it moves the toner from front to rear and sends it to the toner supply roller. Toner is caught in the grooves in the toner supply roller [F].
Toner Hopper Empty Detection [A] [B] A294D307.WMF The toner hopper sensor [A] detects whether there is enough toner in the toner hopper. The toner hopper sensor checks for toner once when the toner supply roller clutch turns on. When there is only a small amount of toner inside the toner hopper and pressure on the toner hopper sensor becomes low, the toner hopper sensor outputs a pulse signal (once per copy).
2.7.5 TONER RECYCLING AND WASTE TONER COLLECTION Overview [C] [B] [A] B070D903.WMF To recycle used toner for re-use, the toner recycling coil in the tube [A] transports the toner collected by the drum cleaning to the toner entrance tank for recycling. To collect waste toner that will no longer be used, the toner collection coil in the tube [B] transports the toner collected by the transfer belt unit to the waste toner collection bottle.
Toner Recycling The toner recycling coil in the tube [A] transports the toner collected by the drum [E] [F] [B] [D] [A] [C] B070D904.WMF B070D906.WMF cleaning unit to the toner entrance tank [B] for recycling. This toner is dropped into the toner entrance tank and mixed with fresh toner from the toner bottle. The toner bank motor [C] drives the toner transport coil via the toner supply coil clutch [D].

Lower Relay Clutch 9. Knob 5. Relay Motor The paper feed motor (1) drives feed, pick-up, and separation rollers in trays 1, 2, and 3 via timing belts, clutches (2), and gears. The paper feed motor also drives the vertical transport rollers and the lower relay roller.
2.8.3 VERTICAL TRANSPORT [A] [C] [B] B070D617.WMFF The vertical transport rollers [A] in each feed unit are all driven by the paper feed motor. The vertical transport rollers and the vertical transport idle rollers [B], on the inner and outer vertical guide plates, transport the paper up from each feed unit towards the relay and registration rollers. The vertical transport guides [C] can be opened to remove jammed paper in the vertical transport area.
2.8.4 PAPER REGISTRATION Overview [A] [C] [E] From the LCT [B] [C] B070D702.WMF The registration sensor [A] is positioned just before the registration rollers [B]. When the paper leading edge activates the registration sensor, the registration motor is off and the registration rollers are not turning. However, the upper relay roller (or LCT relay roller for feed from the LCT) [C] stays on for a bit longer.
2.9 IMAGE TRANSFER AND PAPER SEPARATION 2.9.1 OVERVIEW [B] [A] [F] [C] [E] B070D401.WMF [D] The transfer belt unit consists of the following parts: [A]: Transfer belt A belt (length: 321 mm) with high electrical resistance which holds a high positive electrical potential to attract toner from the drum to the paper. Also, the electrical potential attracts the paper itself and helps the paper to separate from the drum.
2.9.2 TRANSFER BELT UNIT LIFT [C] [E] [A] [D] [E] [B] [F] B070D506.WMF The transfer belt lift solenoid [A] inside the transfer belt unit turns on to raise the transfer belt into contact with the drum. The front lever [B] and the rear lever [C] are connected to the solenoid by links [D], and they push up the stays [E] when the solenoid turns on. The support spring [F] helps the solenoid to raise the transfer belt. The solenoid turns off after the copy job is finished.
2.9.3 TRANSFER BELT CLEANING [B] [C] [D] [A] B070D403.WMF Some toner may adhere to the transfer belt when paper jams occur. The adhered toner must be removed to prevent the rear side of the copy paper from getting dirty. The cleaning blade [A] scrapes off any toner remaining on the transfer belt. This is a counter blade system.
2.9.4 TONER COLLECTION [D] [A] [C] [B] B070D505.WMF Transfer belt drive is transmitted to the toner collection coil [A] through idle gears [B]. The toner collection coil [C] transports the collected toner to the toner recycling unit [D] and from there it goes to the waste toner collection bottle. See Toner Supply and Recycling for details.
2.9.5 DRUM ANTI-CONDENSATION HEATER [A] B070D048.WMF The drum anti-condensation heater [A] is located under the transfer belt unit. It turns on when the main switch is off to prevent moisture from forming on the transfer belt. The heater is included in the machine at the factory, but the connector is not connected.
2.10 FUSING 2.10.1 OVERVIEW [E] [D] [A] [G] [F] [C] [B] [H] [I] B070D501.WMF After transferring the image, the copy paper enters the fusing unit. A heat and pressure process using a hot roller [A] and a pressure roller [B] fuses the image to the copy paper. There are three fusing lamps of different wattage [C] inside the hot roller. They are turned on and off to maintain the target fusing temperature.
2.10.2 OIL SUPPLY AND CLEANING [B] [C] [D] [A] B070D553.WMF [E] B070D504.WMF The oil supply and cleaning web [A] feeds the web felt soaked with silicone oil. Springs [B] hold a roller under the web [C] against the hot roller [D]. This intermediate roller applies a light coat of silicone oil to the hot roller and removes paper dust and toner from the hot roller. A spring clutch inside the mechanism pulls the web to take up the slack, to prevent it getting pulled in between the fusing rollers.
[D] [C] [A] [B] [E] B070D555.WMF SP1902 001 displays the web consumption. When the web consumption exceeds the value set with SP1-902-4 (Web Near End), the machine indicates web near-end on the operation display. The machine still operates while the actuator [A] remains above the web end sensor [B] undetected.
SP1902 004 (Web Near End) can be adjusted to change the near-end period. The defaults for and amount of web that remains for copying are different for NA and EUR/A. Near-End Area NA EUR/A Near-End 90% 86% Web Remaining 600K 350K The table below, provided for your reference, shows approximately how adjustment of SP1902 002 affects the near-end and end displays on the B070 (90 cpm) or B071 (105 cpm).
2.11 PAPER EXIT/DUPLEX 2.11.1 OVERVIEW [A] [B] [C] B070D661.WMF The printed page from the fusing unit goes either straight through to the output tray or finisher, or downward through to the inverter or duplex unit, depending on the position of the junction gate [A]. If the page is fed out directly, it arrives on the tray face-up. If the user selected facedown output, the page goes to the inverter [B] before being fed out.
2.11.2 INVERTER Feed-in and Jogging [A] [D] B070D802.WMF [C] [B] B070D803.WMF The inverter feed roller [A] feeds paper to the jogger section. After the trailing edge of the paper passes through the inverter feed roller, the jogger fences [B] move to square the paper. This happens every page. The jogger motor (a stepper motor) [C] moves the jogger fences [B] inward or outward.
Feed-out [D] [B] [A] B070D804.WMF [C] [E] [B] [F] [C] B070D805.WMF After jogging, the reverse roller solenoid [A] energizes to push down the reverse trigger roller [B]. The reverse roller [C] turns counterclockwise continuously, so the paper starts to reverse when the reverse trigger roller is down and catches the paper between the rollers. The inverter guide plate solenoid [D] energizes to lower the inverter guide plate [E], so that the paper is guided by the inverter guide plate.
2.11.3 DUPLEX TRAY FEED MECHANISM [A] [B] [C] [D] [E] [F] B070D806.WMF In duplex mode, after the paper leaves the inverter, the duplex inverter gate solenoid [A] switches the junction gate [B] to direct the paper to the duplex tray. The paper is fed through the duplex tray by duplex transport rollers 1 [C], 2 [D], 3 [E], and the duplex feed roller [F]. If duplex mode is not selected, the solenoid does not switch the junction gate, and the paper goes to the output tray or finisher face down.
2.11.4 BASIC DUPLEX FEED OPERATION To improve the productivity of duplex copying, a non-stacking style duplex mechanism is adopted. This type of mechanism allows more than one page to be processed at once, in a process called ‘interleaving’. Examples of this are given below. For paper lengths up to A4/Letter LEF, the top duplex speed is possible, with the duplex unit processing four sheets of copy paper at the same time.

5.5 DETAILED DESCRIPTIONS 5.5.1 PAPER FEED [A] [D] [C] [B] B511D113.WMF This LCT has three paper tray feed stations. The upper and middle trays can each hold 1,000 sheets of paper. The lower tray can hold 2,550 sheets of paper. All feed stations use an FRR paper feed system (paper feed roller [A], separation roller [B], pick-up roller [C]), and those rollers are driven by the LCT motor via the paper feed clutch [D].
5.5.2 PICK-UP AND FEED Overview [H] [F] [A] [G] [B] [D] [E] [C] B511D105.WMF Drive from the LCT motor is transmitted to the gear [A] in the paper feed unit via the timing belt [B]. Then the gear [A] transmits the drive to the pick-up [C], paper feed [D], and separation [E] rollers via gears and the paper feed clutch [F]. The gear [A] also transmits the drive to the grip roller [G] via gears and the grip roller clutch [H].
5.5.3 PICK-UP AND FEED [D] [I] [C] [G] [H] [A] [E] [B] [F] B511D105.WMF When a paper feed station is not selected, its separation roller solenoid [A] is deactivated and the separation roller [B] can turn freely. When the paper feed station is selected and the Start key is pressed, the feed clutch [C], separation roller solenoid [A], and pick-up solenoid [D] turn on.
5.5.4 SEPARATION ROLLER RELEASE [B] [C] [A] B511D104.WMF The separation roller [A] is normally away from the feed roller [B]. When the paper feed station is selected, the separation roller solenoid [C] contacts the separation roller with the feed roller as explained on the previous two pages. This contact/release mechanism has the following three advantages: 1. When the LCT motor turns on, all the separation rollers in the three feed stations rotate.
5.6 PAPER LIFT 5.6.1 TRAY DETECTION When a tray is set in the machine, the tray detection method used depends on the tray: • The upper tray and middle tray are detected when any one of the paper size switch signals is low. • The lower tray is detected when the switch 1 signal of the paper size switch is low.

5.6.3 LIFT SENSOR [A] [E] [D] [C] [B] B511D108.WMF When the lift motor turns on, the pick-up solenoid [A] activates to lower the pick-up roller [B]. When the top sheet of paper reaches the proper paper feed level, the paper pushes up the pick-up roller and the actuator [C] on the pick-up roller supporter [D] de-activates the lift sensor [E] to stop the lift motor.
5.7 PAPER SIZE DETECTION [A] [B] 1 2 3 B511D111.WMF SW1 SW2 SW3 A4-LEF B5-LEF A5-LEF A5-SEF LT-LEF 0 1 1 1 0 1 0 1 0 0 0 1 0 0 0 HLTLEF 1 0 0 1: HI HTLSEF 1 1 0 0: LOW Top Tray (Tray 1) and Middle Tray (Tray 2) For the top and middle trays, the paper size switch [A] detects the paper size. The paper size switch contains three microswitches. The paper size switch is actuated by an actuator plate [B] at the rear of the tray.
5.8 REMAINING PAPER DETECTION [E] [A] [D] [C] [B] B511D109.WMF The amount of paper remaining in the tray is detected by the three paper height photointerrupter sensors on the left rail as the bottom plate rises. Five states, determined by the position of the actuator are possible. 1. With the actuator [A] below paper height sensor 1 [B], no sensor is actuated and the display indicates 100%. 2. When the actuator passes paper height sensor 1 [B] , the display indicates 75% of the paper supply remaining.
5.9 PAPER END DETECTION [A] [B] B511D110.WMF The paper end sensor [A] detects the top sheet of the paper in the tray by monitoring the reflected light. When the paper tray runs out of paper, the paper end sensor does not receive the reflected light due to the cutout [B]. Then, the tray lift motor rotates backwards 2 seconds to drop the tray bottom plate.

6.5.2 PRE-STACKING [B] [E] [C] [F] [A] [D] B468D011.WMF During a multiple copy job selected for stapling, the pre-stacking mechanism delays the first two sheets of every set (after the first set) to allow enough time to staple the preceding stack on the stapler tray. Pre-stacking is performed with the first and second sheets for the second and all subsequent sets.
6.5.3 VERTICAL LIFT MECHANISM Overview [A] [B] B468D101.WMF At power on, both trays lower slightly, then the upper tray stops at the feed-out position. The machine is ready for feed out to the upper tray [A] During printing, the upper [A] or lower tray [B] (whichever is selected) is repeatedly lowered until the stack reaches a certain height and then the job halts. The upper tray holds 500 sheets (A4 LEF), and the lower tray holds 2500 sheets.

Normal sorting/stapling, without saddle stitching: When the bottom of the tray actuates sensor [A], the lift motor [B] continues to rotate for a certain number of rotations.
6.5.6 SHIFT MECHANISM [C] [A] [B] [K] [D] [J] [G] [E] [H] [I] [F] B468D105.WMF The same shift mechanism is used for the upper tray and lower tray. Shift Roller Rotation The shift roller [A] is turned by the shift roller motor [B]. Shift Roller Horizontal Movement The shift roller is moved from left to right by the shift motor [C] and shift gear disk [D].
6.5.7 PAPER POSITIONING [C] [F] [G] [D] [E] [B] B468D014.WMF [C] [A] Vertical Alignment When the trailing edge of the copy passes the stapler tray entrance sensor [A], the positioning roller solenoid [B] switches on long enough for the selected paper size and pushes the positioning roller [C] onto the paper. The positioning roller and alignment brush roller [D] rotate to push the paper and align the trailing edge of the paper with the stack stopper [E].
6.5.8 STAPLER Stapling Mechanism [B] [C] [A] B468D015.WMF [D] [E] B468D106.WMF Staple firing is driven by the stapler motor [A] inside the stapler unit. The stapler hammer [B] fires the stapler [C]. The cartridge set sensor [D] detects the cartridge at the correct position, or logs an SC if the stapler unit is not at the correct position. The stapler end sensor [E] detects the staple end condition and logs an SC.
6.5.9 STAPLER MOVEMENT The stapler performs horizontal and rotational movement in each of the four staple modes. Horizontal Stapler Movement [D] [A] [B] [C] B468D016.WMF The stapler movement motor [A] drives the timing belt [B] which moves stapler [C] left and right on a support bar [D]. When the Start key is pressed, the jogger fences move to the wait position 10 mm wider than the selected paper size, the stapler motor switches on and moves the stapler to the staple position and then switches off.
Rotational Stapler Movement [F] [E] [D] [C] [A] [B] B468D017.WMF When the user has selected oblique stapling at one position, first the stapler motor switches on and off for the amount of time needed to move the stapler to the stapling position for the selected paper size. At the correct time, the stapler rotation motor [A] switches on and via the timing belt [B] rotates the worm gear [C].
6.5.10 FEED OUT [D] [I] [C] [A] [B] [H] [G] B468D018.WMF [E] [F] B468D019.WMF After a set has been stapled, the stack feed out motor [A] switches on and drives the stack feed out belt [B]. The pawl [C] on the belt lifts the stapled stack and transports it to the exit rollers [D]. There are two pawls on the belt, to increase productivity.
6.5.11 BOOKLET FINISHING OVERVIEW Stapling: Two booklet staplers are used. These are about half way up the stack fed-out path The stack feed-out belt moves the stack to the correct position for stapling. Folding: This is done in two phases: initial folding and final folding. • Initial folding: At the top of the stack feed-out belt, a plate pushes the centre of the copy (at the stapled place) through a pair of rollers to give the booklet an initial fold. However, this fold is only a partial fold.
6.5.13 INITIAL FOLDING [B] [A] [C] B468D021.WMF [F] [D] [H] [E] [G] B468D022.WMF The folder plate motor [A] switches on and drives the folder plate [B] forward to push the center of the booklet into the nip of the folder rollers [C], giving the booklet a partial fold. This is a detailed cross-section of the operation described above. The timing of the sequence depends on the size of the paper selected for the job.
6.5.14 FINAL FOLDING AND FEED-OUT [J] [C] [D] [G] [H] [F] [I] [E] [A] [B] B468D023.WMF When the finisher is ready to feed out the first stapled booklet, the lower tray [A] descends past the pressure plate slot [J], the spring-loaded arms inside the lower tray snap into the grooves on the side fence, and the springs push the arms against the bottom of the support wing [B] to raise it.
6.6 PUNCH UNIT B377 (OPTION) The punch unit punches holes in printed sheets, one by one. The punch unit is provided with a new punch mechanism to improve the accuracy of punching. NOTE: The illustrations below show the unit for Europe for 2/4 hole punching. The North American unit has five holes for 2/3 hole punching. 6.6.1 PUNCH DRIVE MECHANISM [A] [F] [E] [D] [C] [B] B377D505.WMF The punch motor [A] drives the punch mechanism.
[C] [B] [D] [A] B377D504.WMF When the finisher has received the command that changes the number of punch holes for the job, the punch hole motor [A] turns on until the actuator disk changes the status of the punch hole switch [B] (until it switches on or off). This indicates that the cover [C] and the punch cam [D] have moved to one side or the other to determine which punchers are used.
6.6.2 PUNCH WASTE COLLECTION [A] [B] [C] B377D506.WMF Waste punchouts are collected in the punch waste hopper [A] below the punch unit inside the finisher. When the top of the punchout waste in the hopper reaches and actuates the hopper sensor [B], a message will be displayed on the operation panel after the current job is completed. This sensor also detects whether the punch waste hopper is installed.

7.5.2 PAPER PRE-STACKING [A] [E] [B] [F] [C] [D] B478D000.WMF This mechanism improves productivity in staple mode. It is only used when copying on A4, LT, or B5 (all LEF). During stapling, the copier has to wait. This mechanism reduces the wait by holding the first two sheets of a job while the previous job is still being stapled. It only works during the second and subsequent sets of a multi-set copy job.
7.5.3 JOGGER UNIT PAPER POSITIONING [C] [G] [A] [F] [E] [B] [D] [L] [M] [I] [K] B478D508.WMF [J] In the staple mode, as every sheet of paper arrives in the jogger unit, it is vertically and horizontally aligned, then the staple edge is pressed flat to ensure the edge of the stack is aligned correctly for stapling.
7.5.4 STAPLER UNIT MOVEMENT [A] [B] [C] B478D513.WMF Side-to-Side The stapler motor [A] moves the stapler [B] from side to side. After the start key is pressed, the stapler moves from its home position to the stapling position. If two-staple-position mode is selected, for the first stack the stapler moves to the rear stapling position first, staples, moves to the front position, staples and waits at the front.
[A] [B] [F] [D] B478D514.WMF [E] B478D523.WMF B478D515.WMF [C] Rotation (1) In the oblique staple position mode, the stapler rotation motor [A] rotates the stapler units [B] 45° to counterclockwise after it moves to the stapling position. Rotation (2) When the staple end condition arises, the stapler motor moves the stapler to the front and the stapler rotation motor rotates the stapler unit to clockwise to remove the staple cartridge [C]. This allows the user to add new staples.
7.5.5 STAPLER [C] [E] [A] [D] [A] B478D516.WMF B478D521.WMF [E] [F] B478D522.WMF [G] When the aligned copies are brought to the stapling position by the positioning roller and jogger fences, the staple hammer motor [A] starts stapling. During stapling, the stapler trims off the excess length [B] of the staples by lowering the cutter [C]. This excess length depends on the number of copies in the set; there will be very little for a stack containing 100 sheets.
[C] [D] [A] [B] [E] B478D518.WMF [F] B478D517.WMF The stapler has a staple end sensor [A], cartridge set sensor [B] and staple hammer HP sensor [C]. When a staple end or no cartridge condition is detected, a message is displayed advising the operator to install a staple cartridge. If this condition is detected during a copy job, the indication will appear, and the copy job will stop. The staple cartridge has a clinch area [D] where jammed staples collect.
7.5.6 FEED-OUT [G] [D] [A] [B] [C] [I] [H] [E] B478D519.WMF [F] B478D512.WMF After the copies have been stapled, the stack feed-out motor [A] starts. The pawl [B] on the stack feed-out belt [C] transports the set of stapled copies up and feeds it to the shift tray exit roller [D]. When stapling starts, the exit guide motor [E] opens the upper exit guide [F], which includes the upper shift tray exit roller [G], in order to feed out the leading edge of the copy set smoothly.
7.5.7 PAPER EXIT STACKING [A] [B] [E] [C] [F] [D] [H] [G] [I] B478D524.WMF The stacking roller assembly [A] is fastened to a plate [B] on a shaft by a spring [C]. The cam [D], in contact with the bottom of the plate, is connected to the stacking roller drag motor [E] via a timing belt. The stacking roller drag motor and timing belt rotate the cam against the bottom of the plate to move the rollers forward and back with each sheet ejected onto the shift tray.
7.5.8 SHIFT TRAY Overview [E] [D] [F] [G] [A] [B] [C] B478D010.WMF The shift tray lift motor [A] controls the vertical position of the shift tray [B] through gears and timing belts [C]. Stand-by Mode After the main switch is turned on, or when the stack is removed from the tray, the end of the feeler on the tray falls and its actuator [D] rotates up into staple mode HP sensor 2 [E] (S7) and switches it on.
7.5.9 SHIFT TRAY UP/DOWN MOVEMENT [D] [B] [C] [H] [A] [G] [F] [E] B478D010.WMF Sort/Stack Mode (Shift Mode) The shift tray moves to home position, which is when the actuator [F] has just exited the shift mode home position sensor [G] (S12). During feed-out, the tray is lowered automatically at prescribed intervals; sensor [D] (S7) is ignored.
7.5.10 SHIFT TRAY LOWER LIMIT DETECTION [A] [B] [C] B478D010.WMF This machine has two shift tray lower limit sensors: shift lower limit sensor [A] (S9) for large paper (B4 and larger) and shift lower limit sensor [B] (S11) for small paper (smaller than B4). NOTE: Sensor [C] (S10) is not used. When the actuator [D] enters sensor [A] while using large paper (about 1500 sheets are on the tray), a message will be displayed and copying will stop.
7.5.11 SHIFT TRAY SIDE-TO-SIDE MOVEMENT [D] [A] [F] [C] [B] [E] B478D520.WMF In sort/stack mode, the shift tray [A] moves from side to side to separate the sets of copies. The horizontal position of the shift tray is controlled by the shift motor [B] and shift gear disk [C]. After one set of copies is made and delivered to the shift tray, the shift motor turns on, driving the shift gear disk and the shaft [D]. The end fence [E] is positioned by the shaft, creating the side-to-side movement.
7.6 JAM CONDITIONS 1. The entrance sensor does not turn on when the copier has fed paper 426 mm after the copier exit sensor turned off. 2. The entrance sensor does not turn off when the upper transport motor has fed paper 1.5 times the paper’s length after it turned on. 3. The upper tray exit sensor does not turn on when the upper transport motor has fed paper 574 mm after the entrance sensor turned on. 4. The upper tray exit sensor does not turn off when the upper transport motor has fed paper 1.
7.7 PUNCH UNIT B531 (OPTION) 7.7.1 PUNCH UNIT DRIVE [C] [A] [B] [D] [E] B531D102.WMF The punch unit makes 2 or 3 holes at the trailing edge of the paper. The number of holes depends on a selection made on the operation panel. The cam [A] has 2 punches on one side and 3 punches on the other, and is turned by the punch motor [B]. The punch motor turns on immediately after the trailing edge of the paper passes the entrance sensor. The punches on the cam rotate downward and punch holes in the paper.
7.7.2 PUNCH WASTE COLLECTION [A] [B] [C] B531D103.WMF Punch waste is collected in the punch waste hopper [A] positioned under the punch unit. When the level of the punch waste in the hopper rises as far as the hole [B] in the hopper, the punch waste sensor [C] turns on, stops the job, and triggers a message on the operation to indicate that the hopper is full and must be removed and emptied. The job resumes automatically after the hopper is emptied and returned to the finisher.
