4) Secondary Image Transfer
The image is built up on the ITB (primary image transfer). This image is then transferred onto paper
using the T2 transfer roller (roller transfer system) this process is known as the secondary image
transfer.
* The HVPS applies the Image Transfer Bias voltage to the Image Transfer Roller (T2), this
transfers the image from the belt onto the paper.
* When the image is to be transferred from the ITB to the paper the image transfer roller
pressure contact solenoid is activated and this activates a cam which moves the T2 roller
into contact with the belt.
*After the transfer has taken place any remaining charge on the paper is removed by
applying a charge removal bias (generated in the HVPS) to a charge removal plate
>Type
* Transfer method: Semi-conductive roller contact method
* Effective transferring range: 218mm (i.e. maximum image length)
