A WORD ON COPIER INSTALLATION Improper installation may damage the copier. Please note the following during initial installation and whenever the copier is moved. Do not install your copier in areas that are: ● damp, humid, or very dusty Be sure to allow the required space around the machine for servicing and proper ventilation.

AL-1000/1010 [6] Printing process An OPC drum is used for the photoconductor. (Structure of the OPC drum layers) OPC layer (20microns thick) Pigment layer (0.2 to 0.
AL-1000/1010 (2) Outline of print process Semiconductor laser This printer is a non-impact printer that uses a semiconductor laser and electrostatic print process. This printer uses an OPC (Organic Photo Conductor) for its photoconductive material. First, voltage from the main corona unit charges the drum surface and a latent image is formed on the drum surface using a laser beam. This latent image forms a visible image on the drum surface when toner is applied.
AL-1000/1010 Step-7: Optical discharge (Semiconductor laser) Non-image area Before the drum rotation is stopped, the semiconductor laser is radiated onto the drum to reduce the electrical resistance in the OPC layer and elimate residual charge, providing a uniform state to the drum surface for the next page to be printed. When the electrical resistance is reduced, positive charges on the aluminum layer are moved and neutralized with negative charges on the OPC layer.
AL-1000/1010 Start 1) Because the grid potential is at a low level, the drum potential is at about –400V. (Carrier may not be attracted though the carrier is pulled towards the drum by the electrostatic force of –400V. 2) Developing bias ( –400V) is applied when the photoconductor potential is switched from LOW to HIGH. 3) Once developing bias (–400V) is applied and the photo conductor potential rises to HIGH, toner will not be attracted to the drum. Stop The reverse sequence takes place.
AL-1000/1010 [7] OPERATIONAL DESCRIPTIONS (1) Outline of operation The outline of operation is described referring to the basic configuration.
AL-1000/1010 Sub scanning direction (2) Scanner section Sensor scanning area 1) How to scan documents The scanner has sensors that are arranged in a line. These sensors scan a certain area of a document at a time and deliver outputs sequentially. When the line is finished, the next line is scanned, and this procedure is repeated.
AL-1000/1010 2) Laser beam path (3) Laser unit The image data sent from the MCU (image process circuit) is sent to the LSU (laser unit), where it is converted into laser beams. 1) Basic structure The LSU unit is the writing section of the digital optical system. The semiconductor laser is used as the light source, and images are formed on the OPC drum by the polygon mirror and fθ lens, etc.
AL-1000/1010 B. Separator pawl Fuser section Three separator pawls are used on the upper heat roller. The separator pawls are teflon coated to reduce friction with the roller and prevent a smear on the paper caused by the separator pawl. C. Thermal control 1. The heater lamp, thermistor, main PWB, DC power supply PWB, and triac within the power supply unit are used to control the temperature in the fuser unit.

AL-1000/1010 3. After about 0.1 sec from when the main motor start rotating, the tray paper feed solenoid (PFS) turns on at a moment. This disengages the paper feed latch from the projection of the clutch sleeve, transmitting rotation of the pick-up drive gear to the paper feed roller shaft, rotating the pick-up roller to feed the paper. 6.
AL-1000/1010 3. When pawl C of the manual paper feed clutch sleeve is hung on the manual feed latch, the manual feed stopper falls and the manual take-up roller rises. At that time, the manual paper feed roller is rotating. B. Manual multi paper feed operation 1. Before paper feed operation, the manual paper feed solenoid (MPFS) is turned OFF as shown in the figure below. A A C C OFF MPFS ON MPFS 2.
AL-1000/1010 5. The solenoid turns off to close the gate and return to the initial state. Process unit new drum detection mechanism 1. When the power is turned on, the detection gear 38T is rotated in the arrow direction by the detection gear 20T to push the microswitch (process detection switch) installed to the machine sensor cover, making a judgement as a new drum. Gear 20T Gear 38T A C Process detection switch OFF MPFS C.

When the value of C is increased by 10, the image loss is decreased by 1mm. (Default: 50) 5) Measure the distance (H mm) between the paper lead edge and the image print start position. Set A = 10 × H (mm). (Example: Set the value of A to 50.) When the value of A is increased by 10, the image lead edge is shifted to the paper lead edge by 1mm.
AL-1000/1010 4) If the measurement value is out of the specified range, change the set value and repeat the adjustment procedure. The default value is 50. 2. Copy density adjustment (1) Copy density adjustment timing The copy density adjustment must be performed in the following cases: ● When maintenance is performed. ● When the developing bias/grid bias voltage is adjusted. ● When the optical section is cleaned. ● When a part in the optical section is replaced. ● When the optical section is disassembled.

AL-1000/1010 (4) Heater lamp control circuit (1) Outline The heater lamp control circuit detects the heat roller surface temperature and converts in into a voltage level, which is inputted to the CPU analog input pin. The CPU converts the analog voltage into a digital signal level and compares it with the set value of the simulation to turn on/off the heater lamp according to the level, maintaining the heat roller surface temperature at a constant level.
AL-1000/1010 The lower the heat roller surface temperature is, the greater the thermistor resistance is, and vise versa. Therefore, the lower the heat roller surface temperature is, the higher the thermistor terminal voltage is, and vise versa. The thermistor terminal voltage is inputted to the CPU analog port. The CPU controls ON/OFF of the heater lamp by this input voltage level. [High temperature protect circuit in case of CPU hung up] For IC119 3pin (reference voltage), +5V is divided by the resistor.

AL-1000/1010 (9) Power circuit block diagram Block diagram The power circuit is composed of the main section, the high voltage circuit, the FW signal section, and the heater lamp drive circuit. The main section directly rectifies the AC power current and switch-converts with the DC/DC convertor, and rectifies again and smoothes to form each DC power.
AL-1000/1010 Circuit descriptions (1) Main section a. Noise filter circuit The noise filter circuit of the DC power is composed of L and C as shown in the figure below. It reduces normal mode noises and common mode noises which come from and go to the AC line. The normal mode noises are noises which are generated in the AC line or the output line and are attenuated by C4B and C3. The common mode noises are noise voltages generated between the AC line and GND, and are attenuated by L1 and L2.
AL-1000/1010 (2) FW signal The AC input voltage is full-wave rectified by D5 and D6. When the voltage is divided by resistors R18, R19, and R27 and decreased below 2.5V, the shunt regulator IC7 is turned OFF to turn OFF photo coupler PC3, and turn ON transistor Q3. LOW level output of FW signal is provided. e.
AL-1000/1010 (10) Cl invertor PWB (circuit) CL (Xenon lamp) CL- (CNT) Input +24V Invertor circuit and transformer Output 1.5kV (effective voltage) Circuit description The Two transistors connected in series to the transformer are switched on/off by the control signal (CL-) from the MCU. By this switching operation, the signals are converted into switching pulses and a high frequency power is supplied to the CL (Xenon lamp) by the transformer.
AL-1000/1010 The amplified CCD signal output is sent to the clamp circuit. In the clamp circuit, the black level is clamped to 2V at the BCLK signal timing by the analog switch. The clamped voltage is maintained for one line by the coupling capacitor. The clamped analog signal is impedance-converted and inputted to the AD convertor. The analog signal inputted to the AD convertor is converted into 8bit digital data and passed to the PCU PWB. The machine employs the TCD1501C as the image sensor.
