Before beginning this procedure, turn the printer off and disconnect the power cable.
Removing
STEP 1.
Remove the Hammer Bank from the printer (see Procedure 11, Maintenance Manual).
STEP 2.
Remove the Ribbon Shield from the Hammer Bank (see Procedure 12, Maintenance
Manual).
Be careful when handling the Ribbon Shield. It can be bent easily, which can affect
operation of the printer. It also has very sharp edges that can injure you if you aren’t
careful how you handle it.
STEP 3.
Remove the Air Duct and Cable Clamp from the Hammer Bank (see Procedure 13,
Maintenance Manual).
STEP 4.
Each module has six hammers and is held in place on the carriage by two screws on the
backside of the Hammer Bank. Remove these screws and the individual module can be
removed.
Before removing a defective module, insert strips of tape between it and the modules
immediately adjacent to it. This will protect the coils on adjacent modules during
removal and reinstallation.
