14.1.7 Others

If a machine is brought from a cold to warm room, its inside can start to develop
condensation, leading to various problems.
a. condensation on the BD sensor is likely to cause problems associated with E100
b. condensation on the dust-proof glass is likely to cause poor image density in sub scanning
direction
c. condensation on the contact sensor of the reader unit or on the copyboard glass can cause
light images
d. condensation on the pickup or feed guide can cause paper feed problems
If the problem given in d. above has occurred, dry wipe the units in the feed system. Do not
open the package containing a toner cartridge, developing unit, or drum unit right after it
has been brought in from a cold to warm place to avoid condensation. Be sure to leave it
alone for a while (1 to 2 hr), opening it after it has become fully used to the temperature of
the site.
