Changing print cartridges


Changing print cartridges

When a print cartridge approaches the end of useful life, the control panel displays a message recommending that you order a replacement. The printer can continue to print using the current print cartridge until the control panel displays a message instructing you to replace the cartridge.

The printer uses four colors and has a different print cartridge for each color: black (K), cyan (C), magenta (M), and yellow (Y).

Replace a print cartridge when the printer control panel displays a REPLACE <COLOR> CARTRIDGE message. The control panel display also indicates the color that should be replaced (unless a genuine HP cartridge is not currently installed).


If all of the print cartridges wear out at the same time and you are printing mostly monochrome (black and white), you should change the print mode to MOSTLY BLACK PAGES. See System setup menu for more information.
