PID lock error

When the motor rotates in a direction different from the rotation direction (there was a sudden load abnormality, and the motor rotated in the opposite direction due to the reaction force)
Power is not supplied to the motor, or the motor cannot rotate at all.
The load on the motor is greater than expected.

Step	Confirmation and action	YES	NO
1	Check for foreign objects Check for foreign objects in the path of carriage movement for PW detection.　 No abnormality?	Go to step 2	Remove foreign objects.
2	Check the gear trains for damage Visually check the gear trains of the PW CR Drive mechanism for foreign objects, falling off or damage, and for proper belt installation, and reassemble if necessary. Does the error still occur?	Go to step 3	End
3	Check the cables/harnesses that connect the PW CR Drive Motor and HP Sensor, the HP Sensor and mechanical control board, the mechanical control board and the Main Board. Visually check the cables/harnesses that connect the PW CR Drive Motor and HP Sensor, the HP Sensor and mechanical control board, the mechanical control board and the Main Board, and if there are any cables that are not fully inserted in the connector or disconnected, reconnect them. Does the error still occur?	Go to step 4	End
4	Replace the PW CR Drive Unit Replace the PW CR Drive Unit and see if the symptom described in the defect report occurs again. Does the error still occur?	Go to step 5	End
5	Replace the suspected part Replace the mechanical control board and then the Main Board. Does the error still occur?	Contact Epson local service representatives.	End
