My printer folds top lefthand corner intermittently? why?

I have a hp 4250n which has worked fine for 18-24 months. now every so often it folds the top left corner by about half and inch. it has had a maintnenace kit, and clean can't see any blockages, nor internal issues. very frustrating. fold happens when paper passes through tray one and onto the toner. paper is as permitted in HP's reconmendations. can't understand it?

Do you run labels through the unit? If so, ther is probably a little bit of the glue or label that is inside the feed asm. Hard to find it. Have you tried to open the top door when the paper has fed just under the toner cartridge to see if the bent edge begins at that point. Did the problem appear right after the new maintenance kit? Do you still have the old fuser asm? Reinstall the old fuser and see if problem goes away.

HP 4240n 13,05 error - Not noisy, paper has image on it but will not enter the fuder. The fuser was tried in a different printer and worked fine. I do not think the swing plate gears are engaging. Is this...

If the swing plate gears were bad you and everyone in the room would hear it. When you print check the exit rollers, at the top of the printer. Make sure that they are turning. Maybe the fuser drive gears arn't working. I don't suppose the printer is under warranty, no that's too easy!

Sometimes it's due to low fusing temperature. Certain papers need higher temps. Check the paper supplier or look in the printer setup menus and adjust the paper type to as close as possible to what you have.

Hp c6180 keeps erroring that there's no paper, when it does recognize paper

folded corner is 2 things
a) it's gettig folded somewhere along the paper path ( you would have to stop it at every step to see at what point it gets folded)

b)usually the fuser claws are the problem ( right before the exit the part that gets hot has some claws that ride ON the heat roller 3-5 depending on the machine, one is going bad )
