9. Maintaining the Machine
This chapter describes how to replace supplies and how to clean the machine.
Replacing the Print Cartridge
• Store print cartridge in a cool dark place.
• Actual printable numbers vary depending on image volume and density, number of pages printed
at a time, paper type and size, and environmental conditions such as temperature and humidity.
Toner quality degrades over time. Early replacement of the print cartridge might be necessary.
Therefore, we recommend you always keep a new print cartridge ready.
• For good print quality, the manufacturer recommends that you use genuine toner from the
manufacturer.
• The manufacturer shall not be responsible for any damage or expense that might result from the use
of parts other than genuine parts from the manufacturer with your office products.
• If you try to print while the message "Repl Rqrd: Print Cart. (X)" is being displayed, another
message "Continue printing?" may appear. If this happens, you can print a few pages by pressing
[Yes], although the print quality may be lower. Replace the print cartridge as soon as possible. If
the message "Continue printing?" does not appear, replace the print cartridge immediately.
• Do not allow paper clips, staples, or other small objects to fall inside the machine.
• Do not expose the print cartridge without its cover to direct sunlight for a long time.
• Do not touch the print cartridge's photo conductor unit and the ID chip on the side of the print
cartridge as indicated in the illustration below.
• When removing print cartridges, be careful not to touch the laser scanning unit under the upper
cover (the position shown by the arrow in the illustration below).
