Periodic Routine Maintenance
Use the cleaning brush supplied with the printer. This L-shaped tool
has two cleaning pads: one for the corona wire and the other for the
precharger wire inside the print unit. Use the pad on the shorter
branch engraved “T”.
Remove the print unit and
store it in a dark, level,
steady place. Be careful not
to damage the green drum
surface.
Using the tool
as
shown in this figure, clean
the corona wire. Fit the
positioning cut onto the wire
housing frame and gently
move the tool left and right
two or three times along the
length of the wire to remove
any dirt or other substance.
Be careful not to break or
otherwise damage the wire.
After you have cleaned the printer, install the print unit and close the
upper door.
Cleaning the Paper Guide before the Corona Wire
Perform this procedure when printouts show small spots of toner
smudging especially near the top edge of paper.
Open the upper door and
remove the print unit. Be
careful not to damage the
green drum surface. Look
for dust on the paper guide
before the corona wire. Use
a clean, lint free cloth to
gently remove any dust
from the entire surface of
the paper guide.
