Question about Xerox 212 Laser Printer
Copier was moved...has not been used...when turned on it displays error code U4
That is a fuser code. May be a bad heat rod or just need reset.
Here is how to reset it.
Enter diagnostics, Here is the procedure.
To enter diagnostics:
Hold down ‘0’ while turning on the Power the console will light up. Press ‘Stop/Clear’, the lights will shut off & --- will appear in the display Wait 30 seconds for the optics to complete a self-test before you enter any diagnostic test codes. Never turn off the power before the optics stop moving (or you’ll get a U2 code & possibly some unpleasant noises from the Scan Drive Motor).
Next setp is to use the code to clear the U$ code.
*To clear a fuser code:(401)
Enter diagnostics, wait 30 seconds for the optics to initialize, enter ‘401’ followed by ‘Print’, then shut down the power & wait 10 seconds before switching power back on.
That will normally clear that problem. Often times when a machine has set for a long time they wont warm up right and pop that code.
Another thing, if you can get the machine to warm up and come ot ready then it pops up a U4. Open that right side door. You will see this silver, looks like a small saw blade. It should be silver, but it will have a lot of ink built up on it, take a soft brush and clean it with that.
Let me know, if hte code 401 doesnt clear it, then the heat rod would have to be replaced. If that happens please let me know and we will procede from there.
