1. Removing the Drum Unit

1) Open the top unit, release the developing
assembly.
2) Remove the thumb screw [1], and slide
out the drum unit [2] to the front to remove.
Caution:
• The photosensitive drum is
susceptible to strong light. If it was
subjected to strong light for a long
time, it can cause copies to have
white spots or black lines.
Whenever you have taken out the
drum unit from the copier, be sure to
keep it in the bag used at time of
installation. If the bag is not at hand,
substitute several sheets of fresh
copy paper to wrap the drum unit,
and keep it in a dark place.
• When mounting the drum unit to the
copier, be sure to slide it along the
rails and work with extra care.
