(The end of life of the Ink Supply Tube)
Replace the Ink Supply Tube (INK, SYSTEM, ASSY) and reset the counter using the Adjustment Program. In addition, check the statuses of the CR motor (MOTOR ASSY.,
CR), the driven pulley, the Carriage Unit, and the Head FFC, if any abnormal noise or wear is found, replace the corresponding part(s) along with the Ink Supply Tube.

Replace the CR scale (SCALE, CR).The carriage unit does not operate due to a CR motor failure or some reasons. Move the carriage unit manually to check if it moves smoothly, and fix any abnormality.
Replace the CR motor (MOTOR ASSY., CR).
