Change print cartridges
When a print cartridge approaches the end of its useful life, the control panel displays a message
recommending that you order a replacement. The MFP can continue to print using the current print
cartridge until the control panel displays a message instructing you to replace the cartridge.
The MFP uses four colors and has a different print cartridge for each color: black (K), magenta (M), cyan
(C), and yellow (Y).
Replace a print cartridge when the MFP control panel displays a Replace <color> Cartridge message.
The control panel display will also indicate the color that should be replaced (if a genuine HP cartridge
is currently installed). Replacement instructions are included in the print-cartridge box.
CAUTION If toner gets on clothing, wipe it off with a dry cloth and wash the clothes in cold
water. Hot water sets toner into fabric.
