DC 25 Fault Reset for 664 code

Our Xerox machine had an error code 664 on it and it was shutdown. Our tech said that it was probably due to low voltage to the machine. There have been storms lately that may be affecting the power and I know of a couple times where a circuit breaker was tripped by too many people using space heaters, so it makes sense.

To clear it:

Hold down both the “Copy Darken” and “Interrupt” buttons at the same time
Let go & push 101 and the YES button.
If you are in Service mode then Continue. If not, try again.
Once in Service mode, enter 25 YES then “C” buttons.
The unit should power off and then back on again.
Then you push the “P” button.
Finished.
