    MX-5071S fusing unit

    We have an MX-5071S where the fusing unit (pressure roller) is building up paper dust (i think, because its white)

    After 50 days, we had to go clean the roller because it was causing the paper to curl and jam.

    30 days later, same problem.

    Is there anything we can do about this? Right now, we installed the cleaning roller (DUNT-9555DSZZ) because we are out of options In 30 days, we will go back and look if this has any effect on the buildup.

    Re: MX-5071S fusing unit

    Had this happen as well. I did 2 things (3 actually with firmware)

    1 ran fuser cleaning in Settings/Image adjustment (?) bottom center of screen need to log in as administrator

    2 dropped fuser temp to -5 across the board in sim 43

    Didn't totally get rid of the buildup but it was more manageable

    Good luck
