Help me for error code u4 for xerox 5921


The U4 codes for Xerox machines are for the fuser (heat roller) unit. It's rarely something that you can fix yourself I'm afraid.. Sometimes it pops up from overwork and powering off the machine allows it to cool down but if it keeps coming back you need to get it checked out properly..

Xerox 212 copier

It melted in the fuser and has over heated.
You will need to replace the fuser. Google a business called The parts drop, call and ask for Britt.

Rank xerox 5328 U9

if its a u9-1 code it is the lamp that is faulty. Sometimes it can be the connections either end of the lamp but normally the lamp itself. It will probably cost as much to fix as it would to get a new one to be honest

Xerox Copier Machine - Error U4

The fuser is not warming up.
On that machine under the web there is a thermal fuse on a white plastic mount, it has one screw through it.
It is most likely blown. Possibly caused by a jammed paper in the fuser.
That fusable link needs to be replaced.
