Maintaining Print Quality
To maintain good print quality, clean the printer according to the
schedules and information listed in this chapter.
1. Do a General Cleaning. (See page 77.)
2. Clean the main charger, precharger, and transfer charger. For
cleaning instructions, see page 85 for the main charger, and
page 89 for the precharger and transfer charger.
3. If print quality problems occur, clean the following areas (see
page 68 for tool part numbers):
a. Clean the drum with the drum freshener (only when smears
appear on print samples due to the drum).
b. Clean the LED array and the SELFOC® lens (LED print
head) with the Toraysee™ cloth.
c. Clean the fuser cover glass with a razor blade or the cover
glass scraper.
If the print quality is still poor after cleaning the printer, the chargers
may need to be replaced. Contact your authorized service
representative for further assistance.
NOTE: For replacement intervals, see the maintenance schedules
that begin on page 70.
