TROUBLE SHOOTING Remedies for Service Call Error 76
1134 Integral term overload (PID-load
positioning)
An abnormal load is applied to the CR motor. Check the carriage shaft surface for any foreign matters, and
remove it if any.
Check that the carriage shaft and the contact points between the
carriage unit and the main frame are properly lubricated.
Replace the CR motor (MOTOR ASSY., CR).
See 4.3.5.3 MOTOR ASSY., CR on page 123.
1135 Encoder test error (PID-load positioning) Some abnormalities were found in the encoder test result. Check the CR scale (SCALE, CR) for any dirt, and clean it if any
dirt is observed.
Check the CR encoder (BOARD ASSY., ENCODER, CR) for
incorrect attachment, scratch, dirt, and fix any abnormality.
Replace the CR encoder (BOARD ASSY., ENCODER, CR).
See 4.3.11.2 BOARD ASSY., ENCODER on page 192.
1221 PF measurement error An abnormal load is applied to the PF motor. Check all the parts that are driven by the PF motor for any
abnormal load, and fix any abnormality.
Replace the PF motor (MOTOR, RELEASE, ASSY).
See 4.3.10.3 MOTOR, RELEASE, ASSY. on page 187.
1222 Drive timeover error The condition to stop the PF motor is not satisfied when the PF
motor has driven for a predetermined time period.
Replace the PF motor (MOTOR, RELEASE, ASSY).
See 4.3.10.3 MOTOR, RELEASE, ASSY. on page 187.
Replace the main board (BOARD ASSY., MAIN).
See 4.3.4.1 BOARD ASSY., MAIN on page 113.
1220 Overspeed error The motor speed detected by the PF encorder exceeded the limit. Replace the PF motor (MOTOR, RELEASE, ASSY).
See 4.3.10.3 MOTOR, RELEASE, ASSY. on page 187.
Replace the main board (BOARD ASSY., MAIN).
See 4.3.4.1 BOARD ASSY., MAIN on page 113.
1223 Encoder test error Some abnormalities were found in the encoder test result. Check the PF scale (SCALE, PF) for any dirt, and clean it if any
dirt is observed.
Check the PF encoder (BOARD ASSY., ENCODER, PF) for
incorrect attachment, scratch, dirt, and fix any abnormality.
Replace the PF encoder (BOARD ASSY., ENCODER, PF).
See 4.3.6.2 ENCODER, PF, ASSY. on page 128.
1224 Out of sync. The positioning error detected by the PF encoder fell outside the
specified limits.
Check that the PF timing belt is properly attached.
Check the PF timing belt’s tension. Correct it if not proper.
Replace the PF motor (MOTOR, RELEASE, ASSY).
See 4.3.10.3 MOTOR, RELEASE, ASSY. on page 187.
