Have both a Phaser 840 and 850 that is giving me fits in two areas.
Have researched all error codes and performed all suggested repairs I could find associated with them.
Have scanned this site for possibilities and tried a few things I found here.
I think it time I located the diagnostic software to help me solve the problems. I am specifically looking for about the same routines that is built-in the Phaser 8200.
Any assistance would be greatly appreciated.
