Causes: The ink tubes have reached the end of their service life. (CR scan pass counter has reached a predetermined limit.)
Remedy: Replace the ink tubes and reset the counter.
Code: 1105
Description: CR scale life error
Causes: The CR scale has reached the end of its service life.
Remedy: Replace the CR scale and reset the counter.
Code: 1125
Description: CR HP detection error
Causes: The CR unit does not respond to the CR HP sensor, or the sensor failed to detect the home position. • CR HP sensor failure • False detection of the home due to paper jam or any other obstacle • Misreading of the CR scale • CR lock is damaged.
Remedy: 1. Is the CR HP sensor out of order? Does the shading plate react to the sensor? 2. Is there any paper jammed inside the printer? 3. Does the CR scale have any scratches or dirt? 4. Does the CR encoder work properly? Check it using the Service Program. 5. Does the CR lock function normally? 1. Replace the CR encoder. 2. Re-install the CR encoder. If it is faulty, replace it. 3. Clean the CR scale using ethanol. 4. Replace the CR scale. 5. Replace the CR lock (pump cap unit).
Code: 1137
Description: CR motor broken cable error
Causes: • Connection failure of the interlock switches. • Connection failure of the CR motor.
Remedy: • Check the connection of the interlock switches. • Check the connection of the CR motor. 1. Correct abnormality of the connection if any. 2. Replace the CR motor.
Code: 1138
Description: CR motor overcurrent error
Causes: 1. Connection failure of the motor or the encoder. 2. Number of over current is reached limit of the motor • Irregular load • Encoder failure • Motor failure
Remedy: 1. Does the CR unit move smoothly? Check whether it is stuck and such somewhere. 2. Is there any problem such as damaged cable in the connections below? • CR HP sensor • CR encoder to SUB board (CN102) • CR motor to SUB-M board (CN1) 3. Does the CR encoder work properly? Check it using the Service Program. 1. If there is an abnormal load on the CR unit, correct it. 2. Replace the CR HP sensor. 3. Replace the CR encoder. 4. Replace the CR motor.
