Error Condition
An error signal was detected from the PTR motor (BLM6).
Motor Lock Signal Criteria:
 Rpm of the motor deviates from the target value by more than ±6.25%: not the rated rotation.
 Rpm of the motor deviates from the target value by less than ±6.25%: rated rotation.
Major Cause
 There is excessive torque on the paper transfer roller unit (such as overload due to locked bearing)
 Motor connector is disconnected.
 PTR motor (BLM6) is defective.
 Harness is broken.
 IOB is defective.
Solution
1. Check if the paper transfer roller unit is overloaded (foreign objects in the unit, bearing locked or
stuck).
2. Check the connector of the PTR motor and the harness of the IOB connector (connector floating or
disconnected)
3. Replace the PTR motor (BLM6) .
4. Replace the harness of the PTR motor (BLM6). (if it is broken, or welding is defective)
