Cleaning the printer Over time, particles of toner and paper accumulate inside the printer. This can cause print-quality problems during printing. Cleaning the printer eliminates or reduces these problems. 2 Cleaning the paper path and print-cartridge areas Clean the paper path and print-cartridge areas every time that you change the print cartridge or whenever print-quality problems occur. As much as possible, keep the printer from dust and debris. To clean the inside of the printer 3 1 Turn the printer off and unplug the power cord. 2 Open the top cover. 3 Remove the print cartridge. CAUTION To prevent damage to the print cartridge, do not expose it to light for more than a few minutes. 4 Be careful not to touch the transfer roller (the black, rubber roller located underneath the print cartridge). Skin oils on the roller can cause print-quality problems. 4 With a dry, lint-free cloth, wipe any residue from the paper path area and the print cartridge cavity. 5 Reinstall the print cartridge and close the top cover. 5 Note If the print cartridge is difficult to reinstall, make sure that the registration plate has been flipped back down into position and that you have pushed the print cartridge firmly in place. 6 Plug in the power cable and turn the printer on.
