Color ImageCLASS MF741Dfw will NOT scan


Bought a Color ImageCLASS MF741Cdw a year or so ago and all fine until recently.  Unit is HARDWIRED to a desktop.  Have had this problem for about a month now and when first occurred I deinstalled/reinstalled printer using most current drivers from the Canon Support Page AND downloaded the desktop MF Scan Utility.  Problem seemed to clear until this past weekend.

PROBLEM:  When trying to scan using printer U/I pushbuttons, I receive a "Connect the Computer" error.  When tryng to scan using the MF Scan Utility I receive "Scanner Error 255,0,0"

Sooooo Canon...I see this probelm has persisted for a couple of years now...what is the DEFINITIVE and FINAL solution??
