MAINTENANCE
Periodic Routine Maintenance
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.
