    Toshiba 6550 C391

    I have a Toshiba 6550 that gives me a c391 code, auto toner sensor abnormal lower limit c. I have checked the connector on the EPU tray, replaced the auto toner sensor, DEV mixing unit, EPU board and LGC board. Still getting C391, any ideas. Thanks,

    Check the wiring harness, if not I would be skeptical of epu connector, might pass the check but can still be damaged.
