    tosh 556,656 ~ 557 thermisters interchangeable

    I see 2 different part numbers for these upper thermistors, are they interchangeable or is there a serial number break in use age, or a service bulletin available. thanks in advance.

    The newer part no is counter measure to improve the black streaks issue that might appear on fuser roller
