Important Safety Notices
Prevention of Physical Injury
1. Be sure that the power cord is unplugged before disassembling or assembling parts of the copier or
peripherals.
2. The wall outlet should be near the copier and easily accessible.
3. Note that electrical voltage is supplied to some components of the copier and the paper tray unit even
while the main power switch is off.
4. 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.
5. If you start a job before the copier completes the warm-up or initializing period, keep hands away
from the mechanical and electrical components until job execution has started. The copier will start
making copies as soon as warm-up or initialization is finished.
6. The inside and the metal parts of the fusing unit become extremely hot while the copier is operating.
Be careful to avoid touching those components with your bare hands.
Health Safety Conditions
Toner and developer are nontoxic, but getting either of these into your eyes may cause temporary eye
discomfort. Try to remove with eye drops or flush with water. If material remains in eye or if discomfort
continues, get medical attention.
Observance of Electrical Safety Standards
The copier and its peripherals must be installed and maintained by a customer service representative who
has completed the training course on those relevant models.
• Keep the machine away from flammable liquids, gases, and aerosols. A fire or an explosion might
occur if this precaution is not observed.
Lithium Batteries
Incorrect replacement of lithium battery(s) on the FCU, controller board and memory board unit may pose
risk of explosion. Replace only with the same type or with an equivalent type recommended by the
manufacturer. Discard used batteries in accordance with the manufacturer's instructions.
1
Page 4
Safe and Ecological Disposal
1. Do not incinerate toner bottles or used toner. Toner dust may ignite suddenly if exposed to an open
flame.
2. Dispose of used toner, developer, and organic photoconductors in accordance with local regulations.
(These are nontoxic supplies.)
3. Dispose of replaced parts in accordance with local regulations.
4. When keeping used lithium batteries in order to dispose of them later, do not put more than 100
batteries per sealed box. Storing larger numbers or not sealing them apart may lead to chemical
reactions and heat build-up.
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. The laser
chassis is not repairable in the field. Customer engineers are therefore directed to return all chassis and
laser subsystems to the factory or service depot when replacement of the optical subsystem is required.
• Use of controls not specified in this manual, or performance of adjustments or procedures not specified
in this manual, may result in hazardous radiation exposure.
WARNING FOR LASER UNIT
• Turn off the main switch before attempting any of the procedures in the Laser Unit section. Laser
beams can seriously damage your eyes.

Precautions
General
• Turn off the main power switch and unplug the machine before starting replacement.
Before turning off the main power switch, check that no mechanical component is operating. Mechanical
components may stop out of their home positions if you turn off the main power switch while they are
operating. The component may be damaged if you try to remove it when it is not in the home position.
Lithium Batteries
• Incorrect replacement of lithium battery(s) on the controller or on the fax unit poses risk of explosion.
Replace only with the same type or with an equivalent type recommended by the manufacturer.
Discard used batteries in accordance with the manufacturer’s instructions.
Halogen-free Cable
• Use extreme caution while handling cables.
To comply with local regulations, halogen-free cables are used in this machine. Halogen-free cables are
environment-friendly, but
the following cases:
• The cable is caught between hard objects such as brackets, screws, PCBs, and exterior covers.
• The cable is rubbed on a hard object such as brackets, screws, PCBs, and exterior covers.
• The cable is scratched with a hard object such as brackets, screws, PCBs, exterior covers,
screwdrivers, and fingernails.

Checking the NIP band
You can check the nip band to see if the fusing unit is in a good condition–especially, if the hot roller and
pressure roller are correctly installed.
1. Activate the SP mode.
2. Select SP1-109-001.
3. Specify "1."
4. Press the OK key.
5. Press the key. The copy mode is activated.
6. Place an OHP sheet on the by-pass tray.
7. Press the key. The copier feeds the OHP sheet, and stops it between the hot roller and the pressure
roller for about 20 seconds.
8. Wait until the OHP sheet is output.
9. Press the key.
10. Make sure SP1-109-001 is selected.
11. Specify "0".
12. Press the OK key.
13. Quit the SP mode.
You see an opaque stripe on the OHP sheet. This is the trace of the nip band. The normal nip band is
symmetrical on the OHP sheet. Both ends are slightly thicker than the center.
• There are no specifications or standards for the nip band of this copier.
