It is also used to hold toner inside it.
PAGE 45
Chapter 1 F-1-11 To fully prevent soling of output images caused by toner leakage, be sure to make 3 to 5 test copies after fitting the cartridge in the machine. b. Do not place the cartridge on its end or upside down as shown in following figure. Also, do not swing it. F-1-12 c. Do not open the shutter for the photosensitive drum found under the cartridge and touch the surface of the drum. d. Do not disassemble the cartridge. e. Do not subject the cartridge to unnecessary vibration or impact.
PAGE 46
Chapter 1 Do not throw a cartridge (used or not used) into fire. It may burst or explode. MEMO: If the photosensitive drum is exposed to 1500 lux (general light) for 5 min and then left alone for 5 min in a dark place, it may recover to a level that will not cause practical problems. Nevertheless, avoid direct sunshine by all means, which is as strong as 10000 to 30000 lux. 1.1.4.

Chapter 6 6.1 Construction 6.1.1 Outline 0007-3441 Below illustration shows the construction of the image formation system. The machine is a cartridge type, in which the core of its image formation components are constructed as a signal entity: photosensitive drum, primary charging roller, developing cylinder, cleaning blade, and toner housing. The DC controller PCB has a built-in high-voltage output assembly, and generates high voltage for charging at such times as necessary.

Chapter 7 7.1 Construction 7.1.1 Outline 0006-4065 The machine is not equipped with a paper width detection mechanism. It uses center reference, in which paper moves centered through the pickup/feeding/delivery path. The source of paper may be from any of two: cassette and manual feed tray. Once picked from the cassette or the manual feed tray, the paper is corrected so that any skew is removed by the registration shutter and is sent as far as the registration roller.
PAGE 120
Chapter 7 7.2 Detecting Jams 7.2.1 Jam Detection Outline 7.2.1.1 Outline 0006-4102 The machine is equipped with 6 sensors used to detect jams. The presence/absence of paper is checked with reference to the state of each sensor at such times as stored in the CPU on the DC controller PCB. When the machine detects a jam, it will turn off the main motor (M1) and will indicate a jam message on the LCD. 7.2.1.2 Types of Jams 0006-4103 The machine groups jams into 8 types.
PAGE 121
Chapter 7 - As part of operation after a pickup delay jam, the delivery sensor (PS3) detects paper, the laser is forced OFF, and a specific period of time passes. - At time of cleaning the fixing pressure roller, the trailing edge of paper does not move past the delivery sensor (PS3; i.e., the sensor does not go OFF) within a specific period of time. 7.2.4 Other Jams 7.2.4.
PAGE 122
Chapter 7 7.3 Cassette Pick-Up Unit 7.3.1 Outline 0006-4075 Paper is picked up from the cassette under the control of the CPU on the DC controller PCB and using the drive of the main motor (M1). When the cassette pickup solenoid (SL2) goes ON, the drive of the main motor (M1) is transmitted to the cassette pickup roller assembly to rotate the cassette pickup roller.
PAGE 123
Chapter 7 7.3.3 Detecting the Size of Paper 0006-4084 The machine detects the size of paper in the cassette in any of two ways: LGL size detection and non-LGL size detection. LGL detection is performed by means of a LGL paper sensor (PS101). The LGL size detection mechanism is used to prevent picking up a subsequent sheet of paper before the trailing edge of paper leaves the cassette, otherwise occurring if the pickup was let to occur at the same time using other sizes when picking up LGL paper.
PAGE 124
Chapter 7 7.4 Manual Feed Pickup Unit 7.4.1 Outline 0006-4087 Paper is picked up from the manual feed tray under the control of the CPU on the DC controller PCB and using the drive of the main motor (M1). When the manual feed pickup solenoid (SL1) goes ON, the drive of the main motor (M1) is transmitted as far as the manual feed pickup roller assembly to rotate the manual feed pickup roller.
PAGE 125
Chapter 7 machine executes a retry pickup operation once, the machine will identify the condition as a jam and will indicate a jam message on the LCD. 7.4.3 Detecting the Size of Paper 0006-4091 The size of paper in the manual feed tray is detected using the paper leading edge sensor (PS102) with reference to the length of paper.
PAGE 126
Chapter 7 7.5 Delivery 7.5.1 Outline 0006-4095 The machine uses the following to feed/deliver paper: - registration roller - photosensitive drum - transfer charging roller - fixing pressure roller - delivery roller The paper moved as far as the registration shutter by the work of the various pick operations is corrected for skew movement when it is butted against the registration roller.
PAGE 127
Chapter 7 7.5.3 Reducing the Copying Speed 0006-4099 The machine is not equipped with a paper width detection mechanism; for this reason, if paper with a limited width is used in continuous printing, the ends of the fixing heater would overheat. To prevent overheating, the machine switches among 3 copying speeds with reference to the readings of the sub thermistor. 1. Normally, the machine reduces the speed to 4 ppm when the reading of the sub thermistor reaches 245 deg C/473 deg F or higher. 2.

Chapter 8 8.2 Various Control Mechanisms 8.2.1 Controlling the Speed of the Fixing Roller 8.2.1.1 Controlling the Fixing Temperature 0006-4121 The fixing film unit has a plate-shaped fixing heater built into it for heating the fixing film. The fixing heater is equipped with 2 thermistor: a main thermistor in the middle and a sub thermistor at the end.

Chapter 8 a level 15 deg C/59 deg F lower than paper passage control temperature target. - Paper Passage Temperature Control While printing is taking place, the fixing heater temperature is controlled so that it is ientical with the paper passage control temperature target. - Sheet-to-Sheet Temperature Control To prevent overheating of areas not covered by paper (between sheets), the fixing heater temperature is controlled to a level relatively lower than the paper passage control temperature target.
PAGE 158
Chapter 8 8.3 Protective Functions 8.3.1 Outline 0006-4147 The fixing heater safety circuit is part of the DC controller PCB, and is used to monitor the fixing temperature for an error at all times. If the output voltage for the main thermistor or the sub thermistor reaches about 0.37 V or lower (about 310 deg C/590 deg F), the relay will be turned off regardless of the state of the relay drive signal (RLYD) from the CPU to shut the power to the fixing heater.

Chapter 10 10.1 Basic Construcion 10.1.1 Outline 0006-4330 The ADF is a feeding device used exclusively for stream reading, and its series of operations (original pickup, feeding, delivery) is performed using the drive of the ADF motor (M3). An original picked from the original placement assembly is controlled so that its movement will match the read start timing of the host machine's contact sensor.
PAGE 229
Chapter 10 10.2 Basic Operation 10.2.1 Picking Up and Moving Originals 0006-4332 The ADF picks up and moves originals under the control of the CPU on the host machine's image processor PCB and using the drive of the ADF motor (M3). When the host machine's Start key is pressed, with an original placed in the original tray, the ADF motor starts to rotate counterclockwise and the pickup roller moves down to move up the original stopper.

Chapter 10 10.3 Detection Jams 10.3.1 Outline 0006-4343 The ADF is equipped with 2 sensors to detect original jams. The CPU on the host machine's image processor PCB checks the presence of paper over the sensor at such times as stored in advance; if it identifies a jam, it turns off the ADF motor (M3) and indicates a jam message on the LCD. 10.3.2 Types of Jams 0006-4344 The machine identifies a jam as one of 6 types.
