    Re: CS 255

    I just replaced a main board on one of these yesterday. Same issue: black copies, scans, and sent faxes.

      Found this: Transistor in the CCD drive circuit fails on the Main PWB. Replace main PWB (302K094131). Error C0180 appears on power up (serial number mismatch). Run sim U004 to restore serial number on main PWB. Re-enter network and addressbook data.

      Not old brain cells...The information was simply archived in long tern storage due to non-use of said information within a time period as determined by an algorithm.....
