The copier was working fine, however, now it shows a U4 code and will not do anything. Your help would be greatly appreciated !
A U-6 means the memory on the main board failed.
If the machine is old, the battery on the board is old and not holding the values in the machine.
Replace the main board will correct the problem.
Since it is in the middle deep in the machine you might need to have Xerox repair it for you if they still provide service to this model.
Good luck.
