The blank lamp is wrong, or the part of main lamps of scaning is wrong. Please call to service.

COPIES FROM PANASONIC FP7722 ARE JUST BLOTCHY GRAY


yep!
we can say it is common error/malfunction for these series of fp-77xx
it is also called as quarc error
you may fix it by manually adding some toner at the developing unit
or by pressing USER PRESET + 11 + 1 to perform manual add toner maybe up to 5x until you see some improvement.

U4 code model xerox 5328n dont have the manual


U4-6 Status Codes "Web End of Life"... After replacing the web you must reset the web counter: Hold the "0" while turning the main power on. Then enter "10" & press "Start Print". Enter "63" & "Start Print". Enter "0", display will show CC. Press "Start Print" dn should show. Turn power off & after 10 seconds on again.
You should replace the web soon if your geting that code.

U4-2 code on xerox 5320 copier. Is it the thermistor? Can I replace it and how? Thanks.


Hi,

Yeah, the U4 codes are from the fuser unit.. And no, it's not a user replaceable part..
I'd take it to any half decent printer repair place and see what they say. The 5320 is pretty old so I don't know what the current availability of spares is like..

Copier 212 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.

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.
