    Hi,
    I replace the thermal fuse but it instantly blows. A different power supply from another Brother printer works in faulty unit.
    Diagnosis so far is a faulty power supply.

    What might continue to blow the fuse?

    Update, it seems two diodes and a transistor are faulty.

    I'll replace and update on progress.
