My phaser 7400 suddenly won't print. I can ping it so I know it's on the network. However, in the printer panel under Network Diagnostocs, it says Internal Failure (ND12).
Does anyone have any idea how to fix this?
Thanks so much.
Go to Solution.
Figured out the problem. In case it happens to anyone else here is the cause.
Someone on the network decided to stop using DHCP and configured their own IP Address which just happened to be the same IP Address as the Printer. Ugh! The duplicate IP was causing the issue.
