SERVICE REQ. 00010001: PF motor step-out

Problem
PF motor step-out
 Explanation
This message appears and printer is stopped when the PF motor is determined to
be out of tune because the encoder pulse signal of specified range has not been
input within required time during PF motor rotation or because the pulse is
extremely long or because it is short.
 Check Points
1. No dirt or foreign objects (dust, etc.) on PF encoder or Scale, PF.
2. No abnormality with PF timing belt and proper tension of the belt.
(Refer to 5.3.2 "PF timing belt tension adjustment")
3. No unusual loads on grid roller rotation.
4. PF motor resistance measurement. (approx. 6.7Ω)
If it is shorted, replace the C362DRV Board at the same time.
5. Perform encoder check with self-diagnostic program. (Refer to Chapter 5,
Section 5.3 "Sensor, PF Encoder")
6. Harness connections are correct and no shorts or wire disruptions.
 Solution
1. Replace the PF motor (Refer to 5.3.2 "PF timing belt tension adjustment")
2. Replace the C362DRV board (Refer to 5.2.2 "Parameter Backup")
SERVICE REQ. 00010002: PF motor over current

Problem
PF motor overcurrent
 Explanation
This message appears and printer is stopped when current outside the required
value is detected in the PF motor drive circuit of the C362DRV Board during PF
motor rotation or when the current that must be supplied exceeds the required
value.
 Check Points
Investigate the following items to verify cause.
1. PF motor resistance measurement. (approx. 6.7Ω)
If it is shorted, replace the C362DRV Board at the same time.
2. Visually check for cause (damage, dirt) of poor sensor reading at Scale, PF.
3. Visually check for PF motor harness shorts to frame.
 Solution
1. Replace the C362DRV board
2. Replace the PF motor
