SOURCE: Paper jam at fuser

1. Faulty/blocked fuser exit sensor or faulty/blocked POB sensor. The printer thinks paper is present at one of these sensors when there should not be paper present
Verify that the fuser exit sensor is not stuck
If both sensors are working correctly, the most likely cause is the POB sensor is being blocked by the transfer unit. This can happen if the sensor is out of position, or if the transfer unit's white plastic baffle is out of position. Try bending the POB sensor bracket outward slightly to clear the baffle and retest.
