• The fusing cleaning unit [B] cleans the surface of the fusing belt, removing dust picked up from paper and the pressure roller [A].
  • The cleaning unit uses a heat-resistant web cleaner.
  • The cleaning web [C] unrolls from its supply roller onto a take-up roller [D] as it is used to accumulate paper dust and other matter. The web is treated with a small amount of silicone oil that coats the surface of the fusing belt as it is cleaned.
  • The web motor (a small DC motor) [F] attached to the left bottom corner of the fusing unit drives the web cleaning unit; every time this motor turns on the web feeds a prescribed distance.
  • The portion of the web that has already been used for cleaning is rolled up onto a take-up roller to bring a fresh patch of the web into contact with the belt surface.
