Replacing supply items
This section contains instructions for replacing supply items including print cartridges, the
transfer unit (ETB), and the fuser.
Changing print cartridges
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. Grasp the front cover and pull down, and then grasp the
green handles on the ETB and pull down.
CAUTION
Do not place anything on the ETB while it is open. If the ETB is punctured, print quality
problems may result.
2. Remove the used print cartridge from the printer.
3. Remove the new print cartridge from the bag. Place the used print cartridge in the bag
for recycling. See the enclosed recycling guide in the new toner cartridge box for
replacing instructions.
