Good evening everyone, we have a problem with a xerox workcentre 7225 printer, this printer displays the U code on its controller. According to the documentation, we changed the hard drive, the RAM, the SD card (memory card), and we redid the printer firmware. After all these operations, the printer worked, a few days after this U code is still displayed on the controller and the above operation must be repeated.
What can this be due to?
Thank you in advance for your help.
Judicael.
