Ar-m160 explain warning symbols

SOURCE: Printer problem

Not too sure but might be that the fuser is not warming up as the sudden power loss caused the fuser lamp to blow if not then the control board has a fault.

Thanks J

SOURCE: U 2 error on my Sharp AR M160 copier

U2 is normally a user error (hence U) check that all the doors are closed fully and just recheck the toner installation. If this is all correct it might be a slight possibility that the toner cart is faulty.

Thanks J

SOURCE: Sharp AR-M160 H4 error code

Clearing a trouble code on a AR-M160 is a little different than the AR160.

Try "#" "interrupt" "clear" "interupt" "1" "4" "start key"

This should clear the error. Even if you replace the fusion unit you will need this code to clear the error

You need to contact Sharp ! !

They are the ones who developed the new Windows 7 drivers and now they are defective! Call them back (Sharp), and tell them they need to give you a new driver that will fix the A3 issue of your printer.
