The U2-40 error is the machine telling you that there is a communications error with your CRUM chip.

is there anything at all displayed on the screen??

if there is, press the #, interrupt, C, interrupt in rapid succession. If you don't know what the interrupt button looks like, it is the third button from the right on the control panel. You may have to try it a few times, as with age, the buttons are harder to push so they register that you are pushing them. Once you get into the simulation mode, press 16, then start, and follow the on-screen instructions. once the machine has reset the code, usually shows by going back to the main code screen, then press the CA button, or "clear all".(second button from the right) that will reboot the machine and hopefully clear the code.

Press the following buttons fast: #, interrupt, C, interrupt, C, 14, Start button.

reset u2
press c -interrupt-#-interrupt
press 16
press start
machine off
again machine on
remove this signal.

I was making copies through the document feeder and got the F1 error, and it's blinking and I can't make copies. Any ideas? Thanks!!! Christine

you can get rid of this u2 by pressing buttons as follows: # , interrupt, C, interrupt sequentially. then enter the no. 16 and press the start button. good luck

You might need to run a service mode to reset the machine:

P * C * 14 (start) then 1 for Yes and follow on screen directions, code should clear out.

WHEN THE SHARP AR-5316 PHOTOCOPIER IS SWITCHED ON THE ERROR CODE 4H APPEARSAND THE MACHINE CANNOT BE OPERATED. IHAVE TRIED THE SOLUTION SUGGESTED JUNE THIS YEAR BUT IT DID NOT WORK. WHAT CAN I DO TO GET THE MACHINE TO WORK? IT IS VERY URGENT.

Is that the right sequence for your model? The Sharp copiers I used to work on used either "CROP" (Clear, Reset, '0', Print) or "CPOP" (Clear, Print, '0', Print). I believe Reset and Interrupt is the same key.
