Service Guide

Refer to the fault history when troubleshooting media jams, as this offers the
quickest and easiest method of troubleshooting. There is a shortcut to get the fault
code while the printer is reporting a jam:
For the Phaser 840 printer:
1.
Pull the paper tray out about 1 inch (2.5 cms.). This activates all three
tray sensors.
2.
Hold down the left arrow and press “?” (the help button). This displays
the fault history menu with the most recent code at the top.
For the Phaser 850 printer:
1.
Hold down the left arrow and press “?” (the help button). This displays
the fault history menu with the most recent code at the top.
