Maintaining your printer
Periodically, you need to replace the print cartridge and clean the printer to maintain optimum print
quality. See Replacing the print cartridge and Cleaning the printer for more information.
If several people are using the printer, you may want to designate a key operator to do the setup and
maintenance of your printer. Refer printing problems and maintenance tasks to this key operator.
