McMaster-
Welcome to the forum! That fault code is sometimes caused by a scorotron not being seated correctly, or the PR Module not being seated properly, or even sometimes a dirty Transfer or Detack Dicorotron. In some cases for me its been a dirty MOB & ETAC sensor.
I'd suggest the same as Stiv as well. Do some cleaning...try printing. If you don't have any luck, shut it down and reboot.
I hope to hear a happy ending.
