1.3 Initial Check
Check the following items before attempting to repair the machine.
■ Operating Environment
(1) Put your machine on a flat, stable surface such as a desk that is free of vibration and
shocks.
(2) Use the machine in a well-ventilated room; use the machine 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 machine is not exposed to direct sunlight, excessive heat, moisture, or dust.
■ 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.
(Refer to "2.6.2 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.
■ 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 optical surfaces such as the scanner window, 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, activate the Drum condensation countermeasure mode.
( "5.3 Drum condensation countermeasure mode" in Chapter 7.)
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
end user to allow the unit to come to room temperature before unpacking it. This will take
one or two hours.
