Abstract
The fuser roller and heater rollers of the fusing system can become contaminated with ink and other foreign material when pre-printed materials are run through them. The contamination can create regions of cold spots, which in turn results in poor fusing. Other image defects may result. According the various aspects of the invention, a heater roller cleaner, method and apparatus are provided for applying an array of differential pressure generating areas to a heater roller surface in a fuser assembly while rotating the heater roller surface.
Claims22
A method of cleaning a heater roller located proximate a fuser roller that is heated by the heater roller in a fuser assembly, comprising:
- contacting a heater roller with a web of material which to remove contaminants;
- and
- applying an array of differential pressure generating areas to a heater roller surface in said fuser assembly while rotating said heater roller surface.
A heater roller cleaner located proximate a heater roller and a fuser roller in a fuser assembly such that the heater roller cleaner cleans the heater roller that heats the fuser roller, the heater roller cleaner comprising:
- a web of material which to remove contaminants from the heater and
- an array of differential pressure generating areas applicable to a heater roller surface in fuser assembly.
A fuser cleaning apparatus including a heater roller located proximate a fuser roller that is heated by the heater roller, the fuser cleaning apparatus comprising:
- a heater roller cleaner comprising an array of differential pressure generating areas applicable to a heater roller surface in a fuser assembly.
