HP LaserJet IIP odd noise

... odd noise, that is, and buggered printing.

I was in the middle of a large print job on my old LaserJetIIP, and about 120 pages into it, the printer started making rhythmic "clunk" noises. Not loud ones, just ones that sounded a lot like a gear was slipping somewhere inside. The noises happen more or less two(2) seconds apart. For anyone who has one of these and intends to help me, the following may be helpful:

The trio of "toothed" rollers that are visible when the manual paper feed tray is open turn during printing. However, when this 'clunk' noise happens, they pause briefly. They aren't the problem, i think, because they don't stop at the same point in their rotation (checked)

I don't think it's the intake roller, though it might be... It sounds like the gear is slipping almost directly behind the catch that opens up the front panel of the printer, behind the heating element. However, i couldn't figure out how to remove the felt-covered whatever-it-is safely in order to see behind it.

Also, the printing is smeared - mostly in the last half of the page. This leads me to suspect that there may be something wrong with the post-printing paper rollers, but the problem - that i can't figure out how to get at them - remains.

So, can someone point me at the right part to look at, and/or tell me how to get there?
Take a look at our Fuser Test Page. Look under LX fuser. It has a picture of your fuser and instructions for removal. You want to look at the white gear pictured on the right side. It's missing some teeth. We have them in stock. Easy to replace once you have the fuser out. Email me if you want one.

Thanks, i'll check it out tonight.. The piece the picture showed me didn't look familiar, but i'll see what i can pull apart, and i'll report back. Thanks again.

these printers are not desinged to run large print jobs the laserjet III or later is for that.

Stui's comment notwithstanding, I have a HP IIIP that's just started to do the same thing. I've got the fuser out and in my case it's the gears mounted in the door, not the fuser's gears, that are the problem. Everything's full of unrecognizable white gunk, too. Remains of a dry lubricant?

For the record, the test page states that this printer has printed 86,459 pages.

Usually that's the dust from the grinding of the fuser gear. The gears don't get any lubrication.
