5-Phase Pulse Motor Boards for the Transport Motor Voltages (5PMD)
Use this procedure after installing a new TRANSPORT ROLLER DRIVER BOARD, SUPPLY ROLLER DRIVER
BOARD, or RECEIVE ROLLER DRIVER BOARD. The 3 FILM TRANSPORT MOTORS in the LASER
PRINTER operate with the same type of circuit board, the 5-PHASE PULSE MOTOR BOARD.
Note
There are four versions of the 5-Phase MOTOR BOARD. The version illustrated here contains checks and
adjustments and may be interchanged between the TRANSPORT ROLLER DRIVER BOARD, SUPPLY
ROLLER DRIVER BOARD, and/or RECEIVE ROLLER DRIVER BOARD with correct adjustment. The
three new versions contain no adjustments and are specific to each BOARD. They cannot be interchanged.
Service Parts Management will stock the adjustable style for a universal approach.
