HP Laserjet 4M paper hangs at top delivery

[6rtury]

This is a worsening problem. First 4-6 pages print beautifully. As printer becomes warmer (my observation) the page coming out the top hangs, and eventually they all jam.

I've changed papers but it didn't help. I can only think the rollers are worn, but don't know which ones are responsible or how easy they are to replace. I am handy with repairs, but am working blind here.

Can someone who's had this problem and fixed it give me some directions?

Appreciate it. Kindly email me your responses.

Thanks. :)

Try replacing the upper and lower delivery rollers. This should fix your problem.

Try changing fuser yet? Check p\u roller for misfeed, change toner also.

You can replace the exit rollers (delivery rollers) or the entire exit assembly. That should solve the problem.
