Maintain the print cartridge Maintain the print cartridge To maintain good printing quality, we recommend you occasionally maintain the print cartridge and its associated parts: Clean the print cartridge If characters are not printing completely or white streaks appear in your text, you may have clogged nozzles. Clean the print cartridge as described below: 1. Press Menu repeatedly until TOOLS appears and press OK. 2. Scroll to Clean Cartridge by pressing and press OK. 3. Examine the printed test pattern. • If print quality does not improve, reinstall the cartridge and repeat these steps. • If the line is still broken, wipe the print cartridge contacts. For more information, see Wipe the print cartridge contacts on page 52. Wipe the print cartridge contacts If cleaning the print cartridge as discussed above does not help and you are certain the cartridge has plenty of ink, the problem may be caused by dried ink on the print cartridge contacts or the print cartridge carrier contacts. Follow these two sets of instructions for manual cleaning. Clean the contacts 1. Press Access Cartridge. 2. Open the control panel and cartridge compartment cover and remove the cartridge. See Replace the print cartridge on page 48. 3. Gently blot and wipe the contacts dry. • Use a clean cloth dampened with water to gently clean the entire copper-colored contacts. • To dissolve any dried ink, hold the damp cloth against the contacts for about three seconds. 2 1 CAUTION: Do not touch or clean the ink nozzles. 1 Copper-colored contacts 2 Ink nozzles (do not clean) 52 Care and maintenance
