It is an error caused by repeated, 3 consecutive, fusing late jams. Fusing jam (fusing exit sensor late jam) was detected 3 times
consecutively.
Details:
This SC can be set ON/OFF. The factory setting is OFF; set it
ON when requested by the customer.
SP1-142-001:
0: OFF (factory setting)
1: ON (set by service personnel at the request of customer)
This prevents collateral problems (such as thermistor floating)
that may be caused by repeated jams in the fusing unit
If you do not have a service manual, put a request in the Service Manual Request forum.
