    try the following :
    1. take out the bypass, check the gear on the left hand side for sign of crack.

    2. if you suspect fuser, try replacing it. or inspect the bearing of the pressure roller.

    3. record the noise / make a video of the noise


    any other sign like, toner status "please replace" eventhough you already replace the toner
