Transfer; Fusing - Kyocera Ecosys FS-600 Service Manual

Operation theory
Operation overview

Transfer

The transfer process lets the image developed by the toner on the photoconductive drum
electrically transferred onto paper. The conductive rubber roller applies the positive bias at
the back side of paper, allowing the negatively charged toner transferred onto the paper.
The transfer roller must be handled with great care because oily substances such as
grease can harm not only the transfer roller but the photoconductive drum and other
components in the general proximity.

Max. 2.3 kV

Fusing

The toner on the paper is permanently fused onto the paper as it passes between the
heat roller and the pressure roller in the fuser unit. The toner is molten and pressed into
the paper.
The heat (top) roller has the halogen lamp which is continuously turned on and off by the
thermistor (temperature sensor) to maintain the constant temperature on the heat roller
