Others
1 Do not move a machine that has been stone-cold in a warehouse into a warm
room on all on a sudden. (This generates condensation inside the machine,
and causes various types of troubles)
• E100 error by condensation of the BD Sensor
• Light image density in vertical scanning direction by condensation of the
Dustproof Glas
• Light image density by condensation of the Reader Contact Sensor and
Copyboard Glass.
• Failure in paper feeding by condensation of the Pickup/Feed Guide
2 In the case of the symptom described above, be sure to dry wipe the units of
the pickup/feed system
Condensation tends to occur when unpacking a Toner Bottle/Drum Unit that
has been kept in a cold place and brought into a warm room. To prevent
condensation, be sure to make the part sufficiency accustomed to the room
temperature (leave it for 1 to 2 hours) before unpacking.
