    Yes these are not adjustable but what we did is we pull both sides of the spring to loosen the tension of it.

    However, you might also want to check that the fusing unit isn't binding in some way, and it's sensors can detect proper operation.
    I changed both thermistors in the re build
    thanks for all the info,

    Don't forget to check / update the firmware.

    Engine firmware 1.56:08 (and later)

    The occurrence conditions of SC548 (fusing unit rotation error) were
    changed so that it is triggered only when the abnormal signal is detected 4
    times consecutively (previously, it was triggered with just one detection).

    Hi there!
    Remove the covers arround the 2 sensors, clean the area incl. the fans and change the sensors (they were modified with more space beetween the "windows".
    Greetings...

    My vote: Change photo interrupters as they tend to die especially on the earlier models.

    Another advocate here for checking the photointerruptor on the machine, the little encoder wheel must engage it properly. It often pops out of its mount from rough handing (slamming the fuser back into the machine)

    SC 548 is a fusing unit rotation error. The signal from the sensor for the encoder does not change for 0.5 seconds. Could be bearings binding or other excessive load causing the rotation fusing unit to slow down. Also check/clean the sensor.

    MPC5000 sc 548

    I have the sc548 on the mp5000, i have changed the heat roller because it was dilapidated off the shaft, ive checked the sensors and cleaned them, they are not loose
    the code is intermittent , is there anything else besides the IH inverter ?
Working...
