6.6 IMAGE TRANSFER

6.6.1 OVERVIEW

1. Image Transfer Belt

2. ITB (Image Transfer Belt) Roller

3. ITB Drive Roller

4. ITB Cleaning Unit

The toner is moved from the four OPC drums to the image transfer belt. For a full color print,

all four colors are moved from the PCUs to the transfer belt at the same time. The transfer

roller then moves the four-color toner image from the transfer belt to the paper.

The ITB cleaning unit removes remaining toner from the surface of the ITB after image

transfer.
