Maintaining Print Quality

To maintain good print quality, clean the printer according to the
schedules and information listed in Chapter 5.

1.

Perform a General Cleaning (page 149).

NOTE: Recommended toner vacuum cleaner models are listed on

page 141.

2.

Clean the main charger, precharger, and transfer charger. See
page 154 for the main charger. See page 158 for the
precharger and transfer charger.

3.

If print quality problems occur, clean the following areas:

The drum with the drum freshener (only when smears

appear on print samples due to the drum).

The LED array and the SELFOC

lens (LED print head) with

the Toraysee cloth.

The fuser cover glass with a razor blade or the cover glass

scraper.

If you do not set the desired print quality after cleaning the printer,
you might need to replace the chargers. Contact your authorized
service representative for further assistance.
