Service Cleaning Maintenance Procedure
Cleaning your printer may be necessary if the printer is having print-quality or paper-
feeding problems. Some cleaning procedures, such as purging the jet nozzles are done
automatically when necessary. Other procedures, such as scrubbing the paper-feed
rollers with an alcohol-moistened, lint free wipe, must be done by customers, but only
if the rollers are visibly dirty.
Cleaning may be indicated by any of the following:
■ Light stripes or missing colors appear in prints.
■ Ink smears or random streaks appear on the front or back of prints.
■ Oily spots appear along the tops of prints.
■ Mispicks or multiple picks occur at the media tray.
■ Persistent paper jams inside the printer or at the media tray if the rollers are
visibly dirty.
■ Wiggly vertical stripes caused by too much oil created by a dirty
maintenance kit blade.
■ Most print-quality problems can be corrected by running the cleaning
procedures on the printer’s Control Panel menu.

undesirable residue on the printer parts. Never use water to clean the printer’s
