CHAPTER 2 ERROR INDICATIONS AND
TROUBLESHOOTING
1. INTRODUCTION
Troubleshooting is the countermeasure procedures that the service personnel should follow if
an error or malfunction occurs with the machine. 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 machine 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 machine 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 an
antistatic mat. Also take care not to touch the conductor sections on the flat cables.
(4) Follow the warning by all means.
Warning
Hazard labels as shown below are attached to the machine. Fully understand the
descriptions on the hazard labels and observe them during troubleshooting.
Take extreme care not to remove or damage the hazard labels.

2-2 Confidential
(5) Check again that the portions and parts repaired or removed during the repair work
function properly when the repair is completed.
A certain interface or function could be set to invalid to serve the needs of customers. Ask sales
representative if this is the case before performing the check.
Warning
DO NOT use any flammable spray or flammable solvent such as alcohol,
benzine, or thinner in or around the machine. Otherwise a fire or electric shock
may result.

2-3 Confidential
1.2 Checks before Commencing Troubleshooting
Check the following items before attempting to repair the machine.
Operating environment
(1) The machine is placed on a flat, stable surface.
(2) The machine is used in a clean environment where the temperature is between 10 °C (50
°F) and 32 °C (89.6 °F) and the relative humidity is maintained between 20 % and 80 %.
(3) Ensure the machine is not exposed to direct sunlight, excessive heat, moisture, or dust.
(4) Keep the machine horizontal when you carry it. To prevent injuries when moving or lifting
this machine, make sure to use at least two people.
Power supply
(1) The AC input power supply described on the rating plate of the machine 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.
(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.
Others
(1) Condensation
When the machine is moved from a cold place into a warm room, condensation may occur
inside the machine, causing various problems as listed below.
• Condensation on the surface of optical devices such as the lens, reflecting mirror, and
protection glass, etc., may cause light print image.
• 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 problems.
If condensation has occurred, leave the machine for at least two hours to allow it to reach
room temperature.
If the drum unit is unpacked soon after it is moved to a warm room from a cold location,
condensation may occur inside the unit which may cause printing failure. Leave the drum
unit for one or two hours until it reaches room temperature, and then unpack it.
(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.

2-4 Confidential
Cleaning
Use a soft dry lint-free cloth.
Warning
DO NOT use any flammable spray or flammable solvent such as alcohol, benzine,
or thinner to clean the machine. DO NOT use these articles near the machine.
