2. Photosensitive drum
As a general rule, do not touch the photo-
sensitive drum with your hand nor clean it.
However, if it becomes necessary to clean
it, do so in the following way.
1) Open the upper cover to remove the EP-
W cartridge.
2) Open the protective shutter.
3) Apply toner to a flannel cloth and clean
the dirty drum surface.
Notes: 1. Rotate the drum in the same
direction that it rotates during
printing.
Do not rotate the drum in the
opposite direction as the
connection of the plate spring
that applies developing bias to
the developing cylinder will be
damaged. Do not touch the
photosensitive section of the
drum.
2. Do not use lint-free paper as it
will scratch the drum.
Do not use solvents when
cleaning.
3. Clean the drum quickly as
lengthy exposure to light can
have adverse effects on print
images.
B. Transfer Charging Roller
1. Removal from the printer
1) Open the upper cover.

Notes: 1. Clean the transfer charging
roller only when it becomes very
dirty.
Be careful when cleaning not to
touch the roller or get solvents
or oil on it.
Clean it with dry lint-free paper
(that does not produce paper
dust). Do not use water or
solvents.
2. Replace the transfer charging
roller when you cannot remove
the paper dust, toner, etc. with
the lint-free paper or when it has
deformed.
