Maintaining Your Printer Replacing the Print Cartridges and Cleaning the Printer WARNING C A U T I O N Replacing the Print Cartridges Replaceable print cartridges have been used in your printer, greatly reducing its user maintenance requirements, as these are the components that experience the greatest wear and tear. Under normal use, you will probably find that you have to replace the black cartridge more often than the rest. For instructions on when and how to replace cartridges, see the section starting on page 3-25. Cleaning the Printer Cleaning is limited to the outside of the machine. Use a damp sponge or a soft cloth and household cleaner. To avoid an electric shock, make sure that the printer is switched OFF and unplugged before you clean it. Do not let water get inside the printer. Do not use abrasive cleaners on the printer. Any maintenance or repairs beyond this should be done by a qualified service technician. 8-2
