A U2 is related to a memory failure. May be a bad memory chip or main board. BUT, before we get drastic and move in that direction there are a couple of other things that I have seen cause that.
So, first I have seen the chip on the back of the drum cartridge cause that problem. You can try removing the drum cartridge and powering on the machine without that installed. See if it just comes up with a J2 code then. Or even a CH code. If the code changes you may simply have a failed drum cartridge.
Sometimes memory corruption can occur and you can clear it using this procedure..

Performing a Fault Reset 14 will reset your WorkCentre and will help to clear error codes.

  1. Find the pink Clear button on the Control Panel of the WorkCentre.
  2. Find the button below the word Auto.
  3. Press these buttons in the following sequence: [Clear], [Auto], [Clear], [Auto] NOTE: All of the lights on the Control Panel should go out and the LED Display should go blank. If the lights do not go out, then repeat step 3 until they do. It may be necessary to increase or decrease the pace of the [Clear], [Auto], [Clear], [Auto] sequence.
  4. Press the [10's] key one time and the [1's] key four times to enter '14' in the LED Display, as if you were to make 14 copies.
  5. Press the green [Start] button.
  6. Press the pink [Clear] button two times.
  7. The WorkCentre should now warm up and come to ready.
  8. If the above steps do not clear the error code, repeat steps 3 to 6 a second time.

    If that doesnt resolve your issue, you will probably have to replace the main board. Go on google and look for a place called The Parts Drop. Call them and talk to Britt and see what he can do for you from there parts wise.

Sharp mx 2300N error code U2-41


The U2 errors are usually related to memory or board level issues. You should try to disconnect the fax and network and then kill the main power inside the cover. Turn the main power on and then when you get a solid green light on the control panel press that power switch. If the machine boots with everything disconected then try conecting the options one at a time and try rebooting each time to see if you can narrow down the problem.

U2 91 code


This code may clear by simply switching the machine off via its main power switch.

To reset it using a test simulation try the following:

# * C * then type 16 and press your start / copy key. This should reset the U2 code.

The error is a PCU check sum error.

CalL for service U2-20


Thats a odd one.
That means the machine speed is programed wrong.
Try pressing # * C * , that will enter diagnostice.
Enter 16 which is U2 fault clear and press start, then press 1 and start. DO that a couple of times then press the yellow clear and hte machine will reset.
Or power the machine off and on.
Did you replavce a board or software? Thats a weird code to just pop up.

Sharp AR-285 Error Code ''U2-00'' What does that code mean and can I fix it locally?


A U2-00 is an internal error code from the main processing board's EEPROM (the chip that stores your configuration choices, the copier's serial number, etc.) It can be a faulty EEPROM but most likely the copier took a power hit/glitch and the fault needs to be reset.

To clear the fault make sure the copier is in Copy mode, then press the 'P' key, then the 'Interrupt' key, then the Clear (C) key, then the 'Interrupt' key. This will enter the machine into simulation mode.

Now enter the number 16 and press start. The machine may also ask you to confirm your choice or you may have an 'execute' key on the LCD screen.

Once the fault has been cleared the machine should reboot. If it doesn't, press the 'CA' (clear all) button and the machine should reboot.

If the U2 code persists, you need to call a repair technician to facilitate repairs.

What's U2 code and method for solution


U2 can have several indications.
The most likely one is that the chip that is on the back of the toner cartridge is not seated properly or has failed.
Try with the machine off, removing and inserting the toner cartridge several times to clean the contacts, next step is to try a new toner cartridge.
There is also a connector on the back frame of the machine that may be dirty or going bad.
