n
Read the following information from the
Drum Dot Check Sheet.
 Dot location:
The sheet has eight numbered
columns. The number of the column
with the printed dot in it is used to find
the dot position on the drum.
o
Use the numbered markers next to the
drum roller to find the mark. For
example, a dot in column 2 on the Drum
Dot Check Sheet would mean that there
is a mark in the "2" region of the drum.
Routine maintenance
p
Turn the edge of the drum unit toward
you by hand while looking at the surface
of the suspected area.
NOTE
DO NOT touch the drum's surface. To
avoid print quality problems, hold the
edges of the drum unit.
q
When you find the mark on the drum that
matches the Drum Dot Check Sheet,
wipe the surface of the drum gently with
a dry cotton swab until the mark on the
surface comes off.
IMPORTANT
DO NOT clean the surface of the
photosensitive drum with a sharp object or
any liquids.
r
Turn the drum unit back over.
