Fusing
The final step in the image formation process is the fusing of the toner to the media. The heat and
pressure provided by the fusing assembly serve two purposes: to permanently fuse the toner to the
media and to melt the toner together to produce the full-color image on the page. This process
uses upper and lower rollers made of Teflon tubing to reduce sticking. Both rollers are heated by
Halogen heaters, which cause the four colors to fuse and mix on the paper, creating the permanent
image.
