(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.
