Hi rchapin,Thank you for using the Xerox forum.I would suggest that you review the following solution which was found on our Phaser 6600 Support & Drivers site. There are also many helpful videos there, which could clarify solution steps.
Fault Code 092-672: C Test Patch Err. Power Off / On. Error 092-672 Power Off / On Message.
If that does not resolve your issue you may consider contacting our specific product support experts for customers in the USA at the following link: Fast Track to the Expert If you are outside the USA you should contact the local support center in your area which you can find here:http://www.xerox.com/about-xerox/contact-us/enus.html
