Have you checked the firmware version for both of your machines? The latest available on Xerox.com is PS 4.9.4 / OS 8.54. If your machines do not have this version you should download the firmware and then read the release notes prior to installing it in your machines as there is information in there that you may not be familiar with. Post back to let us know if this helped or not.

Hello again rdf123,
I spoke to the engineers about this issue and both faults are related to the Media Path Motor assembly which would require service. The jam code, M4C2, that you are experiencing could be related to the power to the machine. So check to see if the machine is plugged into a UPS or a power strip. If the machine is plugged into a dedicated outlet then it is the Media Path Motor. Either way, it sounds as if you're going to need to have a Xerox Technician take a look.
I have since had the media drive replaced on both and the firmware updated. I think it was the firmware because the problem was still there on Friday morning after they replaced the media drive Thursday. Since the firmware update, not a problem.
Thanks for all the answers
You're welcome, glad to hear that you are up and running again with both machines. If you can, could you please click on the link in the lower right corner of the post that says Accept as Solution so that if there are other community members with the same problems they know what to try.
