How to Clean the Fuser on an HP Color LaserJet 5550

Updated February 21, 2017

The fuser cartridge is one of the most important consumables in your HP colour LaserJet 5550. Without the fuser cartridge, the ink will not adhere properly to the paper, and that ink will rub off easily when you pick the paper up. Fortunately, you can extend the life of this component by cleaning it periodically.

Shut down the HP 5550 and allow it to cool. The fuser cartridge can get very hot when the printer is in use.

Unplug the printer and turn it around so the back is facing you. Remove the rear access door and locate the fuser cartridge.

Wipe away any fuser oil with a soft cloth. Fuser oil can sometimes leak out of the cartridge during operation, and that oil can contaminate the printer path and reduce print quality.

Clean the inside of the rear door with a small vacuum cleaner. The type of vacuum used to clean computer components works best, but you can also use a handheld vacuum cleaner with a crevice attachment.

Close the rear access door and plug the printer back in. Send a test page to the printer and make sure the ink does not rub off. If the ink still rubs off easily, the fuser cartridge requires replacement.
