Xerox Docucolor 12 prints a blank document when sending to Fiery EX12

[howsimple]

When I purchased the Docucolor 12 copier it can copy from the glass however when sending a job to the EX12 fiery nothing prints. I get a blank document. No error codes shows up. I looked on the Xerox site for any patches for the fiery, but I don't think it is the fiery.

I connected the Fiery EX12 to another docucolor 12 copier and it worked. So, I know it is the copier and not the fiery. Do you know what I need to do so the copier can accept the fiery EX12. It was working fine for months and all of a sudden it started printing nothing. I just get a blank document. Is there a way to go into the diagnostic and correct the problem? Thanks!

If you tried with 2 fiery`s and also check cabels then check VSEL Base TTL PWB (PWB on which connect fiery`s cables), and VSEL Extension PWB
