iR1435iF - Jamming intermittently

[Benjamin98]

Hi all, hope everyone is well.

I've got 2 of the above machines that are jamming intermittently. There is no real pattern I can find. Tested at my workshop and they work well but customer complains when it's back. Recently re-greased the fuser section, all pick-up rollers are fine. I'm seeing that the paper has a few kinks in it once it has come out of the delivery section but they are random. See pic attached

Any help with this would be appreciated
