HP LaserJet M4555 fuser installation instructions

Installing the fuser.

Turn the printer off and unplug the power cord. The fuser might be hot if you have been using the printer. As a safety precaution wait 30 minutes for the fuser to cool before proceeding.

Pull and completely remove the output bin from the side of the printer.

Next, remove the duplexer (if installed).

Next, remove the plastic guide shown in picture below.  You will need to gently flex this guide, there are plastic arms on each side with tabs that hold the guide in place. Slightly flex the guide and release the left arm first, then release the right arm and remove the plastic guide.

While grasping onto both sides of the fuser, push the blue levers upward and pull the fuser straight out.

Install the replacement fuser by inserting it and aligning the left side first. Push the fuser firmly--listen for the sound of both blue levers clicking into place. If the fuser does not click into place you run the risk of wearing out both the fuser and the gears that drive the fuser prematurely. Re-install the plastic guide, duplexer, and rear output bin.

That's it for the fuser install! Remember to send your fuser back to us if you purchased your maintenance kit on exchange. Ship it back in the box we sent if you still have it.
