Question about HP LaserJet 2420 Printer
If the printer was not making the noise before you replaced the fuser unit I would try the following:
1. remove and re-seat the new fuser unit and try a test print.
2. if it still makes noise, remove the new fuser unit and replace the old fuser unit and try a test print. (if you waited untill the printer refused to print on the old fuser this might not work).
If you don't get the noise with the old fuser, then it's possible that the new fuser is defective. You could try returning it for replacement at this point. If you still get the noise with the old fuser, then possibly it is not seated correctly or the latches aren't locked or there is some other unrelated issue.
