Hp HP LaserJet 4100TN


I apologize if this post appears twice. I thought I posted this earlier, but couldn't find that post even using the search button.

Picked up a used HP4100TN today. Counter shows 80k pages printed. Everything I print is blurry, Text/Images have a grey toner outline, almost like its not in focus. There are additional grey scattered around images/text.

Any ideas? I'm guessing toner/fuser? is that a possibility?

You could do a 'halfway' test to check this. start a print then turn the printer off as paper passes under the drum. if the image is fine it's the fuser, if the image is distorted it will probably be the toner.

Your guess is probably right. Toner first then look to the fuser.

The best way to do a half test is to put a sheet of paper on the manual tray and run a self test. When the paper is about 2/3 of the way in lift up on the toner door to stop the printer. Then all you have to do is remove the toner cartridge and look at the sheet below. It will not be fused, but you should be able to see if the print is distorted or not. If it is it may be the toner cartridge, but could also be the laser/scanner assembly. If the image is fine, then it is the fusing assembly. Good Luck.

Okay, ran the test, and stopped it half way thru.... Toner on the paper is picture perfect.

So, the problem now probably lies with the fuser...ouch

Moe, you my friend are a life saver!
I just hope its the film and not the whole fuser. I had priced the fuser between like 150-200+ I think...ugh.

If the toner is fused to the paper it is most likley the teflon cover. If you feel safer with a rebuilt fuser you can contact or as they sell them for about 100.00 on advance exchange.

I hear partsnow is in dire straights. Most of its top echelon defected on Jan. 3rd and started their own company. That included the CEO and $21 million of sales. Ouch! Depot America also had a recent mass exodus that likewise started up a new company. Just a couple of industry tidbits.
