[Jamming] cm 2320, pro 400, pro m476 jamming, not pickup rollers

[Ginbolero]

We have had several of these jamming at registration or at fuser exit randomly and intermittantly.
Most of the time fitting new pick-up and seperation rollers fixes jamming on these things but not always. Jam codes indicate reg and pickup jams.
The following machines all have the same engines and all appear to be doing the same thing, although i've never seen one do it. The customer always phone up the next day saying "It's still jamming"
Canon i sensys 8300, mf 8230, hp laserjet cm 2320, hp pro 400, hp m476 mfp

Any help would be much appriciated.
Thanks.

Well, I've only seen the Pro 400, so you may need to take this for what it is worth.
First of all, do the jams happen from both trays? You may have bad paper, like maybe some of the glue from the wrapper gets on the short edges of the paper, or maybe it got stuck together somehow. As you may already know, fanning the paper will help sometimes, but sometimes you'll just have to get a different ream.
Also, make sure the machine is set for the proper paper type and size.
If the jams only happen when feeding from tray 2, make sure the tray is in good shape. Some people are not gentle with it.

I've had several times where I replaced the PU roller and it seemed to fix it. A few weeks later, they complain again. I replaced the PU roller again (after trying other things) and it seemed to have fixed it for good. I wonder if there was a bad batch of PU rollers somewhere.
