Xerox Alta Link B8045 ADF Not pulling paper

[Reed]

I have a Xerox that will no longer pull the originals from the ADF Original input tray. The problem started when the Dual side scanner in the ADF needed to be replaced. The company I was doing the work for sent an entire ADF which was replaced. Upon replacement the ADF would no longer pull originals from the ADF input tray. I have tested the individual components and they all seem to test fine in service mode. I have replaced the ADF feed motor, ADF control board, Scan control board, All the wire/ribbon cables for ADF. We were even told to replace the Flatbed scanner Power & Data cables. I performed a software & NV Ram Reset nothing seems to be working. The errors that keep coming up after trying to use the ADF are: 319-411 Scan Image Capture DMA & 362-792 Side 1 Doorbell Failure

Thanks in advance..
any help would be appreciated

What fault code does it have? Does it jam running long edge feed? Have you tried sending them short edge feed?
