    another 2 screws - and remove bar with 2 thermistors





    taking away a clip from one side of roller



    then gear, bushing and bearing



    taking away a clip from another side



    then bushing and bearing



    removing old roller



    the new one



    and insert



    i inserting roller, wrapped with protecting film, but it brings more problems than benefits - nex time i will insert roller without film

    assembling parts in reverse order .

    before installing lamps desirable to wipe it with alcohol

    fuses on this plate replaced by polyfuses (or multifuses) - so "fuser chip" is disabled!

    Useful post. Well Done!

    Give more info about FUSES.
    Which make(model) of polyfuses or multifuses have to buy and replace?

    Thank you!
