BizHubC253 error code c3821

Does anybody know what the error code c3821 means?
Or if not, does anyone know if the numbers are sequential for a reason? I see a few problems with codes 3851, I wonder if they're similar?
Thanks for your help.

This error also occurs after a paper jam or a steep power change. If error continues after doors were properly closed and the printer was turned off and on again, it'd be necessary to reset the printer and release it from trouble status.
Turn off the main switch (1/0 botton) but keep the control panel on. Wait 10 seconds. Press and hold Utility Counter botton on the Control Panel while turning on the main switch. Hold it until a white screen with a black dot over the upper rigth corner appears, then release it. Wait for a "trouble reset" botton on the control panel and then manually click on it. You'll see an arrow pointing to an "OK". Now turn off again the main switch, wait 10 seconds, and turn it on. Error must be gone.

C3821: Fusing abnormally low temperature detection (heating side)
cant find the other code.
check that fu is installed correctly, check that right door closes fine.
Check the fusing unit, PRCB and DCPU for
proper connection and correct or change
as necessary.

My panasonic dmrex75 has an error U81 on it. Does anyone know what this means?

This is one of several error codes generated by the main microprocessor IC which are tripped by corruption, preventing proper operation and which may require the processor to be reset or replaced.

The U81 and U80 codes don't mean anything really because the corruption error could be caused by any one of a number of different reasons. It does not point to any specific one fault. This is where the confusion sets in as to the origin of the 'error code' in any device.

Nevertheless, U81 means (in technical terminology) 'microprocessor communication malfunction' on the universal asynchronous receiver/transmitter' or 'microprocessor feedback information error'.

Either way, this is not something an end-user should undertake to repair themselves; it should really go to an authorised service centre. The cost depends on the parts used and the labour, however, it is not unfixable.

!SisRegistryServer error

The error message you got suggests an internal software corruption. I suggest that you update your P990 firmware if it isn't already on the latest firmware and then perform a master reset. This should solve your problem. Don't forget to back up all important data. Good luck!

Flash no more working: error code

You must have an E:61 or E:91 error. You will need to send it back to Sony but, that is what warranties are all about. I am sure it will be fixed quickly and for free!!
