MAINTENANCE
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.
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.
