Others
1 If moving the machine from the cold place such as storage etc to a
warm place abruptly, dew condensation is generated inside machine
and it may cause various troubles.
• E100 occurs due to dew condensation on BD sensor.
• Low image density in the vertical scanning direction due to dew
condensation on the dust-proof glass.
• Low image density due to dew condensation on the reader CCD
and copyboard glass.
• Paper feed failure due to dew condensation on the pickup, feed
guide.
2 If the symptom d appears, wipe the pickup/feed unit with dry cloth.
Moreover, if storing the toner container/developing assembly/drum
unit in the cold place and unpacking them abruptly in warm place,
dew condensation may be generated.
To prevent dew condensation, place them in warm place sufficiently
(for 1 to 2 hours) before unpacking.
