Cleaning the Precharger Wire
The precharger wire is on the print unit. Normally you should not need
to clean this wire. However, the following conditions may indicate that
the wire needs cleaning:
• Your printed pages have dark vertical lines, or the print density is
uneven.
• Cleaning the corona wire does not solve the problem.
Use the cleaning brush supplied with the printer. This L-shaped tool has
two cleaning pads: one for the precharger wire and the other for the
corona wire inside the printer. Use the pad on the longer branch. To
clean the precharger wire, follow these steps:
1. Open the upper door of the
printer.
2. Remove the print unit from
the printer.
Place the unit on
a level, steady place.
3. Clean the wire. To clean the
wire, position the tool as
shown in the figure, then
gently slide it left and right
two or three times along the
length of the wire to remove
any toner or other particles.
Be careful not to break or
otherwise damage the wire.
Notice:
• Avoid exposing the drum to light for more than three minutes.
• Do not touch or scratch the drum surface.
