Changing 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 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), magenta (M), cyan (C), and yellow (Y).
Replace a print cartridge when the printer control panel displays a
REPLACE <COLOR> CARTRIDGE message. The control panel display will
also indicate the color that should be replaced (unless a genuine HP
cartridge is not currently installed).
1 Lift the top cover of the printer.
2 Pull down the front cover and
transfer unit.
CAUTION Do not place any item on the
transfer unit while it is open. If the
transfer unit is punctured, print quality
problems may result.
3 Remove the used print cartridge
from the printer.
