I looked everywhere for the answer to my problem. Not finding the solution, not even the service manual had a fix for this.
Model : HP Color LaserJet 2820
Problem : Top of the printout shows only in the bottom quarter of the page.Sometimes it will jam in fuser, half way out of top, or make it the whole way out.
- Cleaned Rollers
- Clean laser mirror
- Replace Drum
- Replaced Registration Roller Assembly (Roller, flag, and Electronic Sensor)
- Checked gears for problems
- Swap fuser with known working 2820
Any help on this would be very appreciated.

Okay, we found the fix.
We had to restore factory defaults. It seemed to fix the issue. Learn something everyday.

To me it seems like the paper might be being picked up too soon. I can't seem to find any information on what determines the pick-up timing. The issue with that is that if it's picking it up too soon, I would have other sensors telling me that there is a problem because of the timing. Unless it's whatever controls all sensors and their timing.
I tried the service mode : Clean Printer. I got a error "No Paper Pickup" and the paper was sitting just after the drum roller inside.
If the above isn't the issue, then my other idea is that drum rotation is too slow.
Any thoughts or direction to help me with this would appreciated.
