Periodic Routine Maintenance
Notice:
If the print unit is still installed, complete this procedure quickly. You
should avoid exposing the photoconductor drum to light for more than
three minutes.
If you think you need more time, remove the print unit and store it in a
clean, dark place. To remove the unit, see the preceding section
Removing the Print Unit.
Open the upper door and
remove the print unit. Be
careful not to damage the
green drum surface. Look for
spilled toner on the inside of
the printer. Use a damp cloth
to remove any toner stains.
Cleaning the Corona Wire
The corona wire is located in the metallic housing (chrome frame) on the
base frame inside the printer.
Perform this procedure:
• When replacing the print unit
• When the printout shows vertical white lines or printing is too light
Notice:
You should avoid exposing the photoconductor drum to light for more
than three minutes.
Be careful not to break the corona wire.
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.
