communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the end user is
encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
• Consult the dealer or an experienced radio/TV technician for help.

CHAPTER 2 TROUBLESHOOTING
1. INTRODUCTION
Troubleshooting is the countermeasure procedures that the service personnel should follow
if an error or malfunction occurs with the printer. It is impossible to anticipate all of the
possible troubles which may occur in future and determine the troubleshooting procedures,
so this chapter covers some sample troubles. However, those samples will help the service
personnel pinpoint and repair other defective elements.
1.1 Precautions
Be sure to observe and follow all the precautions to prevent any secondary problems from
happening during troubleshooting.
(1) Always turn off the power and unplug the power cable before removing any covers or
PCBs, adjusting the printer and so on. If you need to take voltage measurements with
the power switched on, take the greatest of care not to receive an electric shock.
(2) When connecting or disconnecting cable connectors, make sure that you hold the
connector body and not the cables.
(3) Static electricity charged in your body may damage electronic parts.
Before handling the PCBs, touch a metal portion of the printer to discharge static
electricity charged in your body. When transporting PCBs, be sure to wrap them in
conductive sheets.
When replacing the PCBs, put on a grounding wrist band and perform the job on a
conductive mat. Also take care not to touch the conductor sections on the flat cables.
(4) Follow the warning by all means.
The fuser unit becomes extremely hot during operation. Wait until it has cooled down
sufficiently before replacing consumable items. DO NOT remove or damage the
caution label located on or around the fuser.
WARNING
DO NOT use flammable substances such as alcohol, benzine, thinner or any type of
spray to clean the inside or outside of the printer. Doing this may cause a fire or
electrical shock.
(5) Verify again that the repaired portion works properly.
2-1
Confidential
1.2 Initial Check
Check the following items before attempting to repair the printer.
■ Operating Environment
(1) Put your printer on a flat, stable surface such as a desk that is free of vibration and
shocks.
(2) Use the printer in a well-ventilated room; use the printer within the following ranges of
temperature and humidity: temperature between 10°C and 32.5°C (50°F to 90.5°F), and
the relative humidity is maintained between 20% and 80%.
(3) The printer is not exposed to direct sunlight, excessive heat, moisture, or dust.
(4) Keep the printer horizontal when you carry it.
■ Power Supply
(1) The AC input power supply described on the rating plate of the printer should be within
±10% of the rated voltage.
(2) The AC input power supply is within the regulated value.
(3) The cables and harnesses are connected correctly.
(4) The fuses are not blown.
■ Paper
(1) A recommended type of paper is being used.
(Refer to "1.5.2 Media specifications" in Chapter 1.)
(2) The paper is not damp.
(3) The paper is not short-grained paper or acid paper.
■ Consumable Parts
(1) The drum unit (including the toner cartridge) is installed correctly.
2-2
Confidential
■ Others
(1) Condensation
When the printer is moved from a cold place into a warm room, condensation may occur
inside the printer, causing various problems as listed below.
• Condensation on the optical surfaces such as the lenses, the reflection mirror and the
protection glass may cause the print image to be light.
• If the exposure drum is cold, the electrical resistance of the photosensitive layer is
increased, making it impossible to obtain the correct contrast when printing.
• Condensation on the charge unit may cause corona charge leakage.
• Condensation on the plate and separation pad may cause paper feed failures.
If condensation has occurred, leave the printer for at least two hours to allow it to reach
room temperature.
If the drum unit is unpacked soon after it is moved from a cold place to a warm room,
condensation may occur inside the unit which may cause incorrect images. Instruct the
user to allow the unit to come to room temperature before unpacking it. This will take one
or two hours.
(2) Low temperature
The motor may not drive normally under the low temperature environment. This is due to
there being too much load to drive each unit. In this case, increase the room
temperature.
■ Cleaning
Use a soft dry lint-free cloth.
CAUTION:
DO NOT use flammable substances, any type of spray or any organic solvent/liquids
contains alcohol or ammonia to clean the inside or outside of the printer. Doing this may
cause a fire or electrical shock.
