2 Cleaning the Printer and Accessories To maintain high print quality and performance, thoroughly clean the printer and the paper handling accessories: Every time you change the Toner Cartridge (run a cleaning page). After printing approximately 10,000 pages. Whenever print quality problems occur. Clean the outside surfaces with a lightly water-dampened cloth. Clean the inside parts as indicated in Table 4-1. Observe the warning and caution below. WARNING! Before you begin these steps, turn the printer off and unplug all power cords to avoid shock hazard. Be careful when cleaning around the Fusing Assembly area. It may be hot. CAUTION To avoid permanent damage to the Toner Cartridge, do not use ammonia-based cleaners on or around the printer. Do not touch the Transfer Roller. Skin oils on the roller can reduce print quality. If Toner gets on your clothes, wipe it off with a dry cloth and wash your clothes in cold water. Hot water sets Toner into fabric. Figure 4-1 Location of the Transfer Roller Do Not Touch! 4-2 Printer Maintenance

From the printer s Control Panel, do the following: 1 Press [Menu] until PRINT QUALITY MENU appears. 2 Press [Item] until CREATE CLEANING PAGE appears. 3 Press [Select] to create the cleaning page. 4 Follow the instructions on the cleaning page to complete the cleaning process. Note In order for the cleaning page to work properly, print the page on copier grade paper (not bond or rough paper). You might need to create a cleaning page more than once. When Toner has been cleaned from the Fuser Assembly, shiny black spots will appear on the page s black strip. To ensure good print quality with certain types of paper, use the cleaning page every time the Toner Cartridge is replaced. If the cleaning page is frequently needed, try a different type of paper. Cleaning Spilled Toner Defective Toner Cartridges can develop leaks. Also, after a paper jam has occurred, there may be some Toner remaining on the rollers and guides inside the printer. The pages that print immediately after the jam may pick up this Toner. Clean spilled Toner with a cloth dampened with cold water. Do not touch the Transfer Roller with the damp cloth or with your fingers. Do not use a vacuum cleaner unless it is equipped with a micro-fine particle filter. 4-4 Printer Maintenance
