Page 2 IMPORTANT SAFETY NOTICES PREVENTION OF PHYSICAL INJURY 1. Before disassembling or assembling parts of the copier and peripherals, make sure that the copier power cord is unplugged. 2. The wall outlet should be near the copier and easily accessible. 3. If any adjustment or operation check has to be made with exterior covers off or open while the main switch is turned on, keep hands away from electrified or mechanically driven components.
Page 3: Laser Safety
LASER SAFETY The Center for Devices and Radiological Health (CDRH) prohibits the repair of laser-based optical units in the field. The optical housing unit can only be repaired in a factory or at a location with the requisite equipment. The laser subsystem is replaceable in the field by a qualified Customer Engineer.

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.
Page 33 COPY PROCESS 10 August, 2001 3. LASER EXPOSURE The processed data scanned from the original is retrieved from the memory and transferred to the drum by a laser beam, which forms an electrical 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 BICU board.

10 August, 2001 DEVELOPMENT 2.6.6 TONER DENSITY CONTROL Overview There are four modes for controlling toner supply as shown in the following tables. The mode can be changed with by SP2-921. The factory setting is sensor control 1 mode. Basically, toner density is controlled using the standard TD sensor voltage (Vts), toner supply reference voltage (Vref), actual TD sensor output voltage (Vt), and ID sensor output data (Vsp/Vsg).
Page 75 DEVELOPMENT 10 August, 2001 There are four toner density control modes as follows. Mode Sensor control 1 (SP2-921, “0”): Normally use this setting only Toner supply decision Compare Vt with a reference voltage (Vts or Vref) Toner is supplied to the development unit when Vt is higher Toner control process than the reference voltage (Vts or Vref).
Page 76: Toner Density Sensor Initial Setting
10 August, 2001 DEVELOPMENT Toner density sensor initial setting The TD sensor initial setting procedure is performed automatically when the new PCU is installed in the machine. During TD sensor initial setting, the TD sensor is set so that the TD sensor output to the value of SP2-926 (default: 2.5V). This value will be used as the standard reference voltage (Vts) of the TD sensor.

Page 82: Paper Feed
10 August, 2001 PAPER FEED 2.8 PAPER FEED 2.8.1 OVERVIEW B027D501.WMF There are two paper trays, each of which can hold 500 sheets. The paper tray feed stations use a friction pad system.

PAPER FEED 10 August, 2001 2.8.4 PAPER LIFT MECHANISM B027D521.WMF B027D522.WMF The paper size switch detects when the tray is pushed in. When the paper tray is pushed into the machine, the pin [A] for the lift motor pressure shaft engages the lift motor coupling [B] and the pin [C] for the bottom plate lift shaft in the tray engages the bottom plate pressure lever coupling [D].
Page 86: Paper End Detection
10 August, 2001 PAPER FEED For A4-width paper or wider, a projection [H] on the side fence engages the secondary pressure spring [J] through a lever [I]. Then, the secondary pressure spring [J] applies paper feed pressure in addition to the main pressure spring [K], to ensure that extra pressure is applied to wider paper.
Page 87: Paper Height Detection
PAPER FEED 10 August, 2001 2.8.6 PAPER HEIGHT DETECTION B027D522.WMF The amount of paper in the tray is detected by the combination of on/off signals from two paper height sensors [A] and [B]. The paper amount is displayed on the LCD.
Page 88: Feed Pressure Adjustment For Paper Size
10 August, 2001 PAPER FEED 2.8.7 FEED PRESSURE ADJUSTMENT FOR PAPER SIZE Overview For the friction pad system, the pressure from the top of the stack against the feed rolleris very important for paper feed quality from the paper tray. If the pressure is high, double feed may occur.
Page 89: Feed Pressure Adjustment
PAPER FEED 10 August, 2001 Feed Pressure Adjustment The pressure can be adjusted to solve a paper feed problem. This adjusts the amount of lift motor reverse just after the lift sensor is activated when lifting the stack to the paper feed position. To apply less pressure to the top of the stack, the amount of reverse should be increased.
Page 90: From Paper Near End To Paper End
10 August, 2001 PAPER FEED From paper near end to paper end When paper is used up, the pressure on the bottom plate reduces, so the upward pressure increases, causing the pressure of the feed roller against the top of the stack to increase.

The high voltage supply board supplies a positive current to the transfer roller, which attracts the toner from the drum onto the paper.
Page 96: Image Transfer Current Timing
10 August, 2001 IMAGE TRANSFER AND PAPER SEPARATION 2.9.2 IMAGE TRANSFER CURRENT TIMING There are two transfer current levels: low transfer current level and high transfer current level. The image transfer procedure is as follows: 1. When the CPU receives the image writing start signal, the CPU instructs the high voltage supply board to supply +10µA (low transfer current level) to the roller.
Page 97: Transfer Roller Cleaning
IMAGE TRANSFER AND PAPER SEPARATION 10 August, 2001 2.9.3 TRANSFER ROLLER CLEANING If the paper size is smaller than the image, or if a paper jam occurs during printing, toner may be transferred to the roller surface. To prevent the toner from transferring to the back side of the printouts, the transfer roller requires cleaning before the next printing run.
