Front Sensor Board - Xerox Phaser 7400 Service Manual

Front Sensor Board

The Front Sensor Board is located behind the Front Sensor Board Cover inside the
Registration Assembly.
Note
A spring is used to maintain tension against the retention hooks. This spring is
not captive to either the board or Registration Assembly. Use care not to loose
this spring when removing the board.
1. Remove the Registration Assembly (page 8-84).
2. Disconnect 3 (ENV, PATHICK, and MPTHOME) connectors from the board.
3.
Move the Registration Sensor #1 and Transfer Unit Entrance Sensor Actuators to
allow clearance, and then release the 3 hooks that secure the board to the
assembly.
Replacement Note
Use a piece of non-conductive tape to retain the spring while replacing the
board. Remove the tape just prior to snapping the board into the hooks.
Make sure the Transfer Unit Entrance Sensor Actuator rests on the correct
side of the lower Registration Roller.
