Theory of Operation 2-3
6. Secondary Transfer: The image on the accumulator belt is transferred onto
the print media using the voltage supplied by the transfer roller. The conductive
transfer roller receives a high positive voltage from the HVPS that puts it at a
higher potential than the accumulator belt. Since the transfer roller is located
behind the print media, the 4-color toner image is attracted to the lower potential
and transfers to the surface of the print media.
7. Cleaning:
The accumulator belt cleaner consists of a cleaner blade in contact
with the accumulator belt surface after the point where the toner is transferred to
the print media. Toner remaining on the accumulator belt after the image transfer
to the print media is stored in the waste cartridge.
8. Fixing: The finished toner image is unstable and easily smeared. To fuse the
image, the print media goes through the fuser assembly where it passes between a
pressure belt and the heat roller. The toner is fused onto the print media by the
combination of heat and pressure.
