Cleaning the printer and accessories To maintain superior print quality and performance, use the following procedures to clean the printer and the paper-handling accessories thoroughly every time you change the toner cartridge or whenever print-quality problems occur. General cleaning WARNING! Before you begin these steps, turn the printer off and unplug all power cords to avoid shock hazard. CAUTION Do not use ammonia-based cleaners on or around the printer. While cleaning the printer, be careful not to touch the transfer roller (located underneath the toner cartridge). Skin oils on the roller can cause print-quality problems. To prevent damage, do not expose the toner cartridge to light. Place a piece of paper over the top of the toner cartridge to shield it while it is out of the printer. l Clean the outside of the printer with a water-dampened cloth. l Clean the inside of the printer with a dry, lint-free cloth: • transfer roller • tray 1, tray 2, and tray 3 pickup roller • tray 1, tray 2, and tray 3 separation pad • registration shutter • transfer guide unit • feed belt/feed guide unit • fusing assembly entrance guide Cleaning spilled toner Defective toner cartridges can develop leaks. After a jam has occurred, some toner might remain on the rollers and guides inside the printer. The pages that print immediately after the jam can pick up this toner. Note To clean skin and clothing if toner spills, remove as much toner as possible with dry tissue, then wash with cold water. Hot water causes toner to permanently set into clothing. Vacuum specifications Do not vacuum the printer or any spilled toner using a conventional vacuum. Toner particles used in this product might be too fine for effective vacuuming and could result in damage to conventional vacuums. A vacuum specifically designed for cleaning toner can be used if it is capable of filtering fine particles (5 microns in diameter). C7058-90936 Cleaning the printer and accessories 61
