Re: HP 1022 Fusing problem
I you already replaced the fuser assy and still toner is not fusing, then the Engine Board (ECU) is the next suspect.
Since the printer is an inexpensive model, it is often cheaper to replace than fix.

This could happen due to 1. Worn wiper blade 2. Worn Drum 3. Worn PCR above 3 are inside the toner, if you know how to replace them replace or install a new toner, if the problem still persists you have to check the fuser or contact a technician..
It is either the fuser or toner cartridge. Try a known good toner cartridge. If this solves the problem, then you have a bad toner cartridge. This can often occur when cartridge is near "end of life".
If this doesn't solve the problem, then most likely it is the fusing assembly. You can also try a "half page" test print. Stop the printing in the middle by opening the toner cartridge access door before the paper reaches the fusing assembly. "No defects" , then I would strongly suspect the fusing assembly. HP is replacing these fusers based on Mfg date. of the printer. Call HP if it is a fusing assembly problem.
You need to replace the fusing unit. This is the part that gets hot just before the paper exits the machine. It "fuses" the toner onto the paper. Strange that you are not getting a fuser code if it is not heating up. You may have lost the fusing pressure somehow.
I take it your a tech or have tech ability in my personal experience Squeeking or noticable squeeking has manily from the Output Assembly if you can here it from the rear it is the Output assy. glad i could help
Sounds like a fusing error ... If your able to wipe the toner off the page its a fuser unit problem (replace fuser unit) If toner is sticking to paper but the print quality is poor , replace the drum unit (PCU) good luck
This is what I've seen with wrinkled pages in these machines.
Usually only happens with letter size paper.
At some point a leaking toner was used in the machine the excess toner works its way toward the fuser and builds up on the guide where the paper enters the fusing assm.
You can try to clean the toner thats built up or replace the fuser.
Hope this helps
This issue can be due to fuser. I am sure you have changed the toner cartridge.
To confirm its a fuser issue, please perform the following:
1. Try printing a configuration page from tray 1, pull the top cover, as soon as the media is 60-70% inside the printer.
This would stop the paper before reaching the fusing assy.
2. Remove the paper and check if the line exist.
If exists, fuser is not faulty.
If it does not, then transfer roller, laser/scanner assy is faulty
- If fuser is faulty, perform the cleaning page as following
1. go to configure device > print quality > create/process cleaning page
perform cleaning page 5-6 times, however, if the line is due to fuser, then fuser needs to be changed.
The previous toner cartrige may have been leaking toner in the printer. Even though you changed the toner, there might be leftover toner leakage in the printer. If you can clean that up, it might help the problem. Try running the cleaning mode on the printer if it has one. If there is more than one toner in the printer (if it's a color printer) then it might be one of the other toners. We usually use an electronics vacuum to clean up these messes. If you don't mind making a mess, you can use canned air to blow it out.
