Cleaning and Maintenance Service Cleaning Maintenance Procedure Cleaning Cleaning is indicated 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 is 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 Drum Maintenance Kit blade. ■ Most print-quality problems can be corrected by running the cleaning procedures on the printer's Control Panel menu. Supplies Required ■ 90% pure isopropyl alcohol ■ Foam swabs ■ Alcohol-moistened, lint-free wipes ■ Clear packaging tape Caution Do not use Rubbing Alcohol as it can contain water and oils that leave undesirable residue on the printer parts.
