C2151: 2nd Image Transfer Roller pressure/retraction failure

1 Check the M13 (2nd Image Transfer Pressure/Retraction Motor) connector for proper connection and correct as necessary.
2 PC29 (2nd Image Transfer Pressure/Retraction Sensor) I/O check
3 M13 operation check
4 Change PWB-MC

Clean the Transfer belt retraction sensor. I use a syringe bulb to do that with a pipe attached to it. I could be part a the retraction drive that is faulty. But in my experience it is the sensor. :)
