Service Diagnostics

The Phaser 3425 Laser Printer has built-in diagnostics to aid in troubleshooting 

problems with the printer. The Service Diagnostics Menu provides a means to test 

sensors, motors, switches, clutches, fans and solenoids. Diagnostics also contain 

built-in test prints, cleaning procedures, printer status and some NVRAM access.

Service diagnostics are to be executed through the front panel by a certified service 

technician only. The printer must be rebooted to enter Service Diagnostics:
