The invention relates to cleaning deposits from rollers in a fusing apparatus for a printer. Fuser assemblies and processes for a printer are provided. According to just one aspect of the invention a support is provided. A fusing nip including a plurality of rollers is held by the support. A first roller of the plurality of rollers defines a circumferential surface and is rotatable about an axis in a direction of normal operation. A first cleaning blade is held by the support and defines a first edge in contact with the circumferential surface transverse to the direction of normal operation and is oriented such that rotating the first roller in the direction of normal operation applies a first pushing force to the first cleaning blade. A second cleaning blade is held by the support and defines a second edge in contact with the circumferential surface transverse to the direction of normal operation and is oriented such that rotating the first roller in the direction of normal operation applies a second pushing force to the second cleaning blade.

Print fuser and process with multiple cleaning blades

The fusing assembly in an electrophotographic copier has a paper travel path passing between a pair of opposed air cooling plenums. Each plenum has an air supply plate confronting the travel path with slots for directing cooling air onto the moving paper. The lower plenum plate includes upstanding ribs parallel to the paper travel path for guiding the moving paper and spacing the paper from the plate to improve airflow by decreasing airflow impedance.
