Page 24 Multi Purpose Tray When the paper take-up solenoid 1 (SL3) energizes, the transport motor (M2) drives the paper take-up roller via the paper take-up clutch. The paper take-up roller rotates one revolution. At the same time, the depressing cam rotates and releases the paper lift-up plate to feed the top sheet of paper.
Page 25 Second Cassette (Tray 1) When paper take-up solenoid 2 (SL7) energizes it rotates the paper take-up roller which feeds the top sheet of paper. Paper empty sensor 2 (PC11) detects paper in the second cassette. Paper near empty sensor 1 (PC10) detects when the number of sheets of paper in the tray becomes less than 50.

Page 27: Drum Cartridge Toner Full Detection
Drum Cartridge Toner Full Detection The drum cartridge toner full board (PWB-D1), on top of the image transfer belt assembly, determines when the PC drum waste toner box is full. Waste toner full is detected by an LED (LED1) and a photo-sensor (PT1) on the PWB-D1.
Page 28: Synchronizing Rollers
Synchronizing Rollers The synchronizing rollers adjust any skewed paper transported from the paper take-up/feed section. The rollers match the leading edge of the image on the image transfer belt with the leading edge of the paper. The paper synchronizing sensor (PC1) detects when the leading edge of paper has reached the synchronizing rollers.
Page 29: Paper Type Detection
Paper Type Detection The overhead projection (OHP) sheet detect board (PWB-D2), con- sisting of an LED (LED1) and a photo sensor (PT1), determines whether transparencies or plain paper is being fed through the machine. When plain paper is feeding, the light from the LED reflects off the surface of the paper, and strikes PT1.
Page 30 When a sheet of OHP transparencies is feeding, the light from the LED passes through and PT1 receives no light. General Information 1-9...
Page 31: Development
Development Toner Empty / Toner Cartridge Detection Toner Empty Detection Light from the toner empty detection LED (LED1) on the toner empty/toner cartridge detecting board (PWB-B) is reflected by a mir- ror in the toner cartridge and received by photo sensor (PT1). The amount of light received by the photo sensor determines whether the toner is empty or nearly empty.
Page 32: Aidc Sensor And Erase Lamp
Toner Cartridge Detection Light from the toner cartridge detection LED (LED2) on the toner empty/toner cartridge detecting board (PWB-B) is reflected by the toner cartridge surface to the photo sensor (PT1).

2. Diagnostic Information The diagnostic information in this chapter leads you to the failing part. Before you replace an entire assembly, determine if just the defective part is available in the parts catalog. Some diagnostic pro- cedures indicate the parts catalog location of the part to be checked by including the assembly number and reference number in paren- thesis.

3. Repair Information Precautions for Disassembly and Cleaning Observe the following precautions whenever you service the printer: • Be sure to unplug the printer from the outlet before attempting to service the printer. • To reassemble the printer, reverse the order of disassembly unless otherwise specified.
Page 98: Precautions For Handling The Drum Cartridge
During Replacement: • Before you unplug connectors from the circuit boards, be sure the power cord has been unplugged from the power outlet. • When you remove a board from its conductive bag or case, do not touch the pins of the ICs or the printed pattern. Place it in position by holding only the edges of the board.
Page 99: Precautions For Handling The Laser Equipment
Precautions for Handling the Laser Equipment • When a service job needs to be performed in the laser beam path, such as when working around the printhead and the drum cartridge, be sure to turn the printer off first. • A highly reflective tool can be dangerous if it is brought into the laser beam path.
