    Default HP LaserJet 4050 Grinding

    Hello All,

    Good Morning!

    I am experiencing a grinding sound coming from the back of the printer. At first, I thought the noise was an issue due to the Fuser. However, after switching out the fuser I learned that the sound is deriving from a internal gear wheel which aligns with the fuser's gear.

    The sound occurs immediately when the printer is turned on (initializing phase).

    Any thoughts or ideas on what I could do to prevent the noise?
    Also, I am contemplating on using lubrication.

    Thanks,
