My machine sharp MX 3100N is giving the error code U2-05, what steps should i use to solve it

This error refers to a discrepancy between the HDD & the machine. If the hard drive has not been swapped out & nothing has changed on the machine then try resetting the copier to see if that rectifies it.
To reset the machine you will need to enter simulation mode.
First, make sure the copier is in COPY mode.
Then press the following 4 keys in quick succession: # * C *
You should then have a screen showing simulation mode.
Then enter 16 & press either of the copy keys (black or colour).
This should then display U2 ERROR RESET.
Press EXECUTE, YES then press the CA key.
The machine will exit simulation mode & restart.
If after restart the machine displays U2 again then you will probably have a HDD fault. Unfortunately, the HDD would have to be replaced by an authorised dealer as new Firmware would have to be reload to allow the machine to recognise a new HDD.
Hope this helps.

How do I correct error U2-40 on Sharp AR-M236

U2-40 is the error code for the toner cartridge.
It indicates a fault with the chip in the cartridge.
Try entering simulation mode to reset the error first, to do this make sure the machine is in COPY mode.
Then press the following 4 keys in order: #*C*
then enter 16 & press the copy start key.
Then follow the instructions on the screen to reset U2 error.
When complete, press CA key to exit simulation mode.
If the error re-occurs then the toner cartridge will have to be replaced & the machine reset again as above.
Hope this helps.

Sharp mx-3111u error u2-91

The error you have is a miscommunication between the PCB's within the copier.
To reset the machine you will need to enter simulation mode.
Make sure the machine is in COPY mode.
You need to press the following 4 keys in quick succession:
Once in simulation mode enter 16 & press the copy start key.
Then press EXECUTE, then YES then press the CA key.
The machine will then restart.
IMPORTANT! Do not enter any other simulations as this could render the copier inoperable.
This will reset the U2 error. If the code is still there after resetting the machine then it is likely you have a PCB failure which will require the intervention of an authorised dealer.
Hope this helps.

I have a Sharp MX-6201N copier that is showing error code U2-10. Does anyone know what that means and how to fix it ? Any advice greatly appreciated !

U2-10 is 'SRAM user authentication check sum error'

Press P * C * to enter the service 'simulation' mode then enter 16 on the key pad and press the start button.
You will be in U code clear.
Press 'execute' on the screen.
The machine should reboot.
It may start to work again.
If not you will need to replace either SRAM chip or the main board.
