Dell 3310 printer ink system failure fix.

Hold the number 9 key and the key down at the same time, then pull the power cord. Then put the power cord back in while holding the 9 and # key. You will lose your settings, but the ink system failure message should go away.

The OK-cancel-black-color procedure is to be done when turning the printer **OFF** not on.
Then when you turn it back on you'll see "NVRAM RESET" (or something like that) on the display.
It might take a couple of tries.
This is a fix if the problem is not a hardware failure. This same "ink system failure" error also displays if there is a hardware failure and this cannot be corrected with the button/power off technique.
Good luck.
