Xerox 7545 - Scanner Fault - Fault Code 362.476.00

Hello,

We have a Xerox 7545 and this problem has been driving me absolutely nuts.  The image attached shows the Scanner Fault message.  The error code is 362.476.00.  The machine can print, but no copying or scanning.  I followed the directions, powering off and then back on, but that doesn't work.  I don't know what to do.

I really hope someone can help us with this problem.  

Thank you!!
