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, light-
ning rods, ground cables for telephone lines and water pipes or faucets not approved by the proper
authorities. ..........................................................................................................................................

CAUTION:

• 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-
tion. .....................................................................................................................................................

• Advice customers that they must always follow the safety warnings and precautions in the copier’s
instruction handbook. .........................................................................................................................
 [CONFIDENTIAL]

2. Precautions for Maintenance

WARNING

• Always remove the power plug from the wall outlet before starting machine disassembly. ................

• Always follow the procedures for maintenance described in the service manual and other related
brochures. ..........................................................................................................................................

• 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-
dent. ...................................................................................................................................................

• When the service manual or other serious brochure specifies a distance or gap for installation of a
part, always use the correct scale and measure carefully. ..................................................................

• Always check that the copier is correctly connected to an outlet with a ground connection. ...............

• Check that the power cable covering is free of damage. Check that the power plug is dust-free. If it
is dirty, clean it to remove the risk of fire or electric shock. .................................................................

• Never attempt to disassemble the optical unit in machines using lasers. Leaking laser light may
damage eyesight. ...............................................................................................................................

• 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. ...........................................................................................................
 [CONFIDENTIAL]

• 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-
ately. ...................................................................................................................................................

3. Miscellaneous

WARNING

• Never attempt to heat the drum or expose it to any organic solvents such as alcohol, other than the
specified refiner; it may generate toxic gas. ........................................................................................

• Keep the machine away from flammable liquids, gases, and aerosols. A fire or an electric shock
might occur. ........................................................................................................................................

(11)Loading Paper
(11-1)Precaution for Loading Paper

Before loading paper in the cassette, fan the paper taken from a new package to separate it in the procedures below.

Fan the paper and align the edges at the flat place.
In addition, note the following points.
If the paper is curled or folded, straighten it before loading. Such paper may cause a jam.
If paper is left under high temperature and high humidity after taking it out of the package, it may cause trouble with
paper absorbing moisture. After setting paper in the cassette, seal the rest of the paper in the paper storage bag. Also,
seal the paper remaining on the MP tray in the paper storage bag.
If paper is left in the cassette for a long period, heat from the cassette heater may discolor it.
If the machine will not be used for a prolonged period, protect all paper from humidity by removing it from the cassettes
and sealing it in the paper storage bag.

IMPORTANT
If you reuse paper already used for printing, remove staples or clips. Do not use paper with a staple
or clip. This may cause poor image quality or malfunctions.

After completing installation, execute communication test to check if FAX normally operates.

IMPORTANT
Note the following points when installing the FAX system in the line via ISDN or PBX.
Check if the line to connect supports the V.34 (Super G3) FAX communication.
Especially, when communicating between extensions in PBX (private line via TDM), only
14400bps or 9600bps of FAX communication speed is guaranteed and communication errors
or TX/RX image failure may occur at V.34 communication in such a line.

Corrective Measures
Set the following maintenance mode if the communication speed guaranteed on the line is 14400bps or less.
U633 [Enables or disables the V.34 communication]: Off (See page 6-258)
U630 [Setting TX speed and RX speed] (See page 6-253)

(9)Fuser section
The paper from the transfer and separation section is pinched between the heat roller and the press roller. The fuser
roller is heated by the IH, and the paper is pressed by the press roller with the pressure added by the pressure spring
toward the fuser roller, so toner is fused on the paper by that heat and pressure.
The surface temperature of the fuser roller and the press roller is detected by the fuser thermistor and controlled by the
Engine PWB.

(2-1)Paper deck section
The deck can load 1750 sheets paper (64 g/m2) or 1500 sheets paper (80 g/m2). Paper from the deck is picked up by
rotating the pickup roller and is conveyed to the main unit by rotating the paper feed roller. Multi-feeding is also
prevented by the effect of the retard roller.

The paper feeder is comprised of the right- and left-hand cassettes and their feeding units, and the paper feeding
section for the left-hand cassette.
The paper loaded on the lifting plate in the right-hand cassette is picked up one by one by PF forwarding pulley 1, PF
paper feed pulley 1 and PF separation pulley 1. And then the PF paper feed roller 1 feeds the paper into the main unit.
The paper fed by the left-hand cassette is separated in the similar manner and fed out by the conveying roller into the
main unit.

When handling the PWBs (printed wiring boards), do not touch parts with bare hands. Make sure not to damage the
PWB.
If ICs are mounted on the PWB, do not touch them by hand or something charged with electrostatic.
Make sure to release the hook before disconnecting the connector with the hook.
Take care not to pinch up the wire and cable.
Use the original screws when reassembling the parts once disassembled.
If the types and the sizes of screws are not sure, Refer to the parts list.
(2)Storage and handling of the drum
Note the following when handling and storing the drum.
When detaching the drum unit, never expose the drum surface to strong direct light.
Store in the range of ambient temperature of -20 to 40 degree C(–4°F to 104°F) and ambient humidity of 85% RH or
less. Wait more than 5 seconds between the power off and on. Avoid storing the drum unit in the place where the
temperature and humidity may suddenly change even if these changes are within the tolerable range.
Avoid exposure to any substance which is harmful or may affect the quality of the drum.
Do not touch the drum surface with any object.
Make sure not to touch the drum surface with bare hands or gloves.
If the drum is touched by hands or stained with oil, clean it.

Appendixes > Firmware environment commands

9 - 2 Firmware environment commands

The printer maintains a number of printing parameters in its memory. These parameters may be changed permanently
with the FRPO (Firmware RePrOgram) commands.
This section provides information on how to use the FRPO command and its parameters using examples.
Using FRPO commands for reprogramming the firmware
The current settings of the FRPO parameters are listed as the optional values on the service status page.

Before changing any FRPO parameters, print out a service status page, so you will know the
parametervalues before the changes are made. To return FRPO parameters to their factory default
