I have never had a laser printer before. But, the other day one of my managers at work instructed me to throw this one in the dumpster...OR, if I wanted it I could have it. So.... I brought it home to see what might have been the problem (Other than it being "HP") that caused him to want to throw it away. Got it home and got it up and running...no problem with that part. But, it definitely was missing ink cartridges. I ordered some via Amazon and they were delivered late this afternoon...one day, free delivery! I got the ink installed and fired it up. First off, HP doesn't like 3rd party ink...but it accepted them. For a test print I simply went to the settings and did a Clean function and then a Print Quality print out. Here's where the "problem" surfaced: There are "smudges" of some image repeated down the left side of any print out. I've read that it's likely a problem with the fuser...the element that heats up and fuses the ink to the page. I "think" there may have been a...or more than one...paper jam that caused a page to stick to the fuser causing a "burn in image" on it. Am I on the right track here? If this is the case, can the fuser be cleaned in such a way to make it usable again? I'm keen to take the unit apart and try. OR, is it better to replace it? I could do that also, I'm quite sure. As it stands, since I got it for zero cost...other than buying the ink so far, I think it might be worth trying. UPDATED: As I understand it, once the print out starts showing this "ghost" images, it means the fuser is shot. Best...and only option...if one wants to keep using this printer is to replace the kit.
