imageCLASS MF644Cdw Error 853 prohibiting "copy" function

[Jerry-s]

Our Canon ImageClass MF644Cdw won't copy.  We can print, but the copy function produces errors every time.  We're prompted to shut it off, and error E-302-0001 displays.  The shut down never fixes the problem.

In the copy status, the error is described as #853.  In reviewing the possible causes for #853, none make any sense in copy mode.  They all seem to deal with memory, document size or security settings as transmitted from a pc.  The copy function should all happening at the Canon interface so those issues would not apply.

Can anyone help?

I have more info to add.  It's not just the copy function that won't work.  Fax also won't work and brings us to the same error E-302-0001 and the direction to shut down so the issue seems to be in the scanning of the document.  #853 shows up in the report for this failed fax attempt as well.
