Platen Plate Guide Rod Screws
Never loosen the center screws of the brackets that hold the platen plate guide rod in place. The platen
plates should never be removed.
Sensor and Temperature/Humidity Sensor Bracket
This screw is paint locked. However, this bracket must be removed in order to remove the carriage unit.
The bracket must be reinstalled at exactly the same position so the sensors are positioned correctly.
