Re: Help me for error code u4 for xerox 5921
Hi,
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..
