Hi dj_talkman,
Thank you for using the Xerox forum.
I have researched this fault and could not find similar posts, articles etc.
I would suggest that you review the Phaser Product Support site for messages or symptoms that my help find a solution.
If that does not resolve your issue you may consider contacting our specific product support experts:
If you are outside the USA you should contact the local support center in your area which you can find here:
