Abstract
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.

In an electrophotographic copier employing a fuser assembly including an air-operated paper cooler having a pair of opposed air supply plates confronting the paper travel path, the improvement comprising:
- (a) spaced upstanding ribs formed on at least one of said plates parallel to the paper travel path for guiding the paper and spacing the moving paper from said plate;
- and
- (b) air flow apertures formed in said plate between said ribs.
An air supply station for cooling copy paper in the fuser assembly of an electrophotographic copier comprising:
- (a) an upper air supply plenum positioned above the path of travel of the paper from the fuser rolls;
- and
- (b) a lower air supply plenum positioned below the path of travel of the paper from the fuser rolls having a plate confronting the paper travel path with upstanding ribs spaced across its width to guide the paper and space it from the plate surface, and having air slots positioned between the ribs.
