1. Installation Precautions
WARNING
• Do not use a power supply with a voltage other than that specified. Avoid multiple connections to
one outlet: they may cause fire or electric shock. When using an extension cable, always check that
it is adequate for the rated current. .....................................................................................................
• Connect the ground wire to a suitable grounding point. Not grounding the copier may cause fire or
electric shock. Connecting the earth wire to an object not approved for the purpose may cause
explosion or electric shock. Never connect the ground cable to any of the following: gas pipes, lightning rods, ground cables for telephone lines and water pipes or faucets not approved by the proper
• Do not place the copier on an infirm or angled surface: the copier may tip over, causing injury. .........
• Do not install the copier in a humid or dusty place. This may cause fire or electric shock. .................
• Do not install the copier near a radiator, heater, other heat source or near flammable material. This
may cause fire. ...................................................................................................................................
• Allow sufficient space around the copier to allow the ventilation grills to keep the machine as cool
as possible. Insufficient ventilation may cause heat buildup and poor copying performance. ............
• Always handle the machine by the correct locations when moving it. .................................................
• Always use anti-toppling and locking devices on copiers so equipped. Failure to do this may cause
the copier to move unexpectedly or topple, leading to injury. ..............................................................
• Avoid inhaling toner or developer excessively. Protect the eyes. If toner or developer is accidentally
ingested, drink a lot of water to dilute it in the stomach and obtain medical attention immediately.
If it gets into the eyes, rinse immediately with copious amounts of water and obtain medical atten-
• Under no circumstances attempt to bypass or disable safety features including safety mechanisms
and protective circuits. ........................................................................................................................
• Always use parts having the correct specifications. ............................................................................
• Always use the thermostat or thermal fuse specified in the service manual or other related brochure
when replacing them. Using a piece of wire, for example, could lead to fire or other serious acci-
• Handle the charger sections with care. They are charged to high potentials and may cause electric
shock if handled improperly. ...............................................................................................................
CAUTION
• Wear safe clothing. If wearing loose clothing or accessories such as ties, make sure they are safely
secured so they will not be caught in rotating sections. ......................................................................
• Use utmost caution when working on a powered machine. Keep away from chains and belts. ..........
• Handle the fixing section with care to avoid burns as it can be extremely hot. ..................................
• Check that the fixing unit thermistor, heat and press rollers are clean. Dirt on them can cause
abnormally high temperatures. ...........................................................................................................
• Do not remove the ozone filter, if any, from the copier except for routine replacement. ......................
• Do not pull on the AC power cord or connector wires on high-voltage components when removing
them; always hold the plug itself. ........................................................................................................
• Do not route the power cable where it may be stood on or trapped. If necessary, protect it with a
cable cover or other appropriate item. ................................................................................................
• Treat the ends of the wire carefully when installing a new charger wire to avoid electric leaks. ..........
• Remove toner completely from electronic components. .....................................................................
• Run wire harnesses carefully so that wires will not be trapped or damaged. ......................................
• After maintenance, always check that all the parts, screws, connectors and wires that were
removed, have been refitted correctly. Special attention should be paid to any forgotten connector,
trapped wire and missing screws. .......................................................................................................
• Check that all the caution labels that should be present on the machine according to the instruction
handbook are clean and not peeling. Replace with new ones if necessary. .......................................
• Handle greases and solvents with care by following the instructions below: ......................................
· Use only a small amount of solvent at a time, being careful not to spill. Wipe spills off completely.
· Ventilate the room well while using grease or solvents.
· Allow applied solvents to evaporate completely before refitting the covers or turning the power
switch on.
· Always wash hands afterwards.
• Never dispose of toner or toner bottles in fire. Toner may cause sparks when exposed directly to
fire in a furnace, etc. ...........................................................................................................................
• Should smoke be seen coming from the copier, remove the power plug from the wall outlet immedi-

(2) Optical section
The optical section consists of the image scanner section for scanning the original and the laser scanner
section to write the image.
(2-1) Image scanner unit
The original image is exposed by the exposure lamp (LED) and the reflection light is scanned by the CIS
image sensor and converted to the electric signal.
When using the document processor, the image scanner unit stops at the original scanning position (slit
glass) and scans the image from the original conveyed in the document processor.
The charged drum surface is scanned by the laser emitted from the laser scanner units. The laser reflects
to the polygon mirrors by rotating the polygon motor so that the laser scans horizontally to the image. The
laser scanner unit has some lenses and mirrors, that adjust the diameter of the laser to focus the laser to
the drum surface.

(5) Conveying/Transfer and Separation section
Conveying section conveys paper to the transfer and separation section after adjusting the paper position at
the registration rollers.
The transfer and separation section consists of the transfer roller and separation needles attached to the
paper conveying unit. The DC bias is impressed to the transfer roller by the high-voltage PWB (HVPWB), and
the toner image formed on the drum is transferred to the paper by the potential gap. Then, the paper is separated by the drum curvature separation. and discharged by the grounded separation brush *1

(6) Fuser section
Paper from the transfer and separation section is pinched between the fuser belt and the press roller. The
fuser belt is heated by the fuser heater and pressed by the press roller pressed by the fuser pressure
spring. The toner is fused on the paper with heat and pressure.
The surface temperature of the heat roller is detected by the fuser thermistor and controlled by the main/
engine PWB. If the fuser section has abnormal high temperature, the power supply line is shut off by
switching the fuser thermostat and the fuser heater is turned off forcibly.

The original feed section consisting of the parts in the figure, feeds and conveys the original on the original
tray to the original conveying section by the rotation of the DP forwarding pulley and DP feed roller.
The 2nd side of the conveyed original is scanned *1 when passing the CIS and the 1st side at the optical
section (CIS) in the main unit when passing the DP slit glass. The original already scanned is ejected to the
original eject table by the eject roller.
The cassette can 300 sheets paper (64 g/m2) or 250 sheets paper (80 g/m2). Paper fed from the cassette
is picked up by the rotation of the pickup roller and is conveyed to the main unit by the rotation of the paper
feed roller and conveying roller. Multi-feeding is also prevented by the effect of the retard roller.
