Xerox Phaser 7400 Service Manual

Theory of Operation 2-9
5. Fusing: The Fuser uses a combination of heat and pressure to bond the toner
image to the paper.
6. Transfer Unit Cleaning: Toner remaining on the Transfer Unit belt is removed
by a cleaning blade and transported by Auger to the toner waste port.
7. Imaging Unit Cleaning: Toner remaining on the drum, following image
transfer to the media, is scraped off by a cleaning blade and collected.
8. Paper Exit: The paper is then advanced either upward to the Top Exit or
downward towards the Side Exit depending on the Exit Gate position.
9. Waste Toner Recovery: Excess toner collected from the Imaging Unit drums
and the Transfer Unit belt is carried by an Auger Tube to the Waste Toner
Reservoir located behind the Front Door.
