CR lock error

The CR encoder failed to read the CR scale during a predetermined time period. The carriage unit does not operate due to a CR motor failure or some reasons.

Replace the CR encoder (BOARD ASSY., ENCODER, CR). Replace the CR scale (SCALE, CR). Move the carriage unit manually to check if it moves smoothly, and fix any abnormality. Replace the CR motor (MOTOR ASSY., CR).
