I ran out of grey ink and I am getting error message U163, which is freezing up the printer. Upon booting up it goes to the error message screen and then I cannot navigate away from it with any of the buttons. Is there anyway to bypass this to print or scan without the grey ink? None of the ink replacement kits have the grey and it is tough to find. I just want to scan for now... I don't need ink to scan.

SOURCE: The following ink has run out

Press and hold stop/reset for 5 seconds to disable the function. Printer should now print

Firstly I suspect you are not using genuine cartridge or you have refilled the cartridge.
To fix this you need to disable the ink checking procedure.

Do you know that low ink or ink has run out message appears once cartridge empty. If you want to use refill ink in that cartridge then you need to deactivate ink level to get your printer run as usual. Check the following tips to fix low ink error message in case of refill ink usage. Below some methods to deactivate ink level detection function for some models due to its similarity.
