Cleaning the media path might extend the life of the printer. ENWW Cleaning the printer 51 NOTE For best results use a sheet of transparency. If you do not have any transparencies, you can use copier-grade media, 70 to 90 g/m2 (18 to 24 lb), with a smooth surface. Make sure that the printer is idle and the Ready light is on. Access the printer properties (or printing preferences in Windows 2000 and XP). See Printer properties (driver) for instructions. NOTE The cleaning process takes approximately 3 minutes. The cleaning page will stop periodically during the cleaning process. Do not turn the printer off until the cleaning process has finished. You might need to repeat the cleaning process several times to thoroughly clean the printer. 52 Chapter 5 Maintenance ENWW Changing the pickup roller Normal use with good media causes wear. The use of poor media might require more frequent replacement of the pickup roller. If the printer regularly mispicks (no media feeds through), you might need to change or clean the pickup roller. See Ordering supplies to order a new pickup roller. CAUTION Failure to complete this procedure might damage the printer. Turn the printer off, and then unplug the power cord from the printer. Wait for the printer to cool. CAUTION To prevent damage to the print cartridge, minimize its exposure to direct light. Cover the print cartridge with a sheet of paper. Open the print cartridge door, and remove the print cartridge. ENWW Changing the pickup roller 53 3.

If the print quality begins to degrade under these circumstances, you must install a new print cartridge, even if there is toner supply remaining in the cartridge. This life expectancy assumes that you set the print density to 3 and turn EconoMode off. [. . . ]
