Mpc4502 wrinkling through fuser

[Tatteous]

This can be either one of the following:

• Damp paper
• Faulty PTR
• Fuser duplex rollers stuck (if doing duplex)
• Fuser entrance guide warped or dirty
• Uneven fuser pressure

There is a bulletin about the tines on the ptr. They stick out after a jam removal. Replace the PTR. If possible, use a scale to accurately measure both sides of the lead edge to see if the paper is skewed before entering the fuser.

Replaced entire separation assembly and works perfect again. I can’t see any problem with old one but something is wrong with it.

Congrats!

Wrinkles came back. Noticed that the little metal tangs on the transfer roller were sticking up and scraping the paper. Pushed back down and a few copies later same thing. Took the two springs (op and non op side) of the transfer roller and taped the assembly down and it started working fine! Seems something that is supposed to pushed that assembly down and away from the paper is not working. So now I am on the hunt for this!

The shape of the PTR has been changed. It should be replaced with new for best results.
