Transfer section

The transfer section comprises the transfer charger belt for transferring the toner image on the drum onto the paper, and
conveying the paper after transfer to the fuser section, the transfer roller for applying the transfer bias to the transfer
charger belt, etc.
When the paper passes between the drum and the transfer charger belt, the transfer bias current output from the transfer
high voltage PWB (THVPWB) is applied to the transfer roller.
This effects the transfer charging and the toner image developed on the drum is transferred to the paper.
Also, through the transfer charge, the transfer charger belt is charged and pulls the paper and separates it from the drum.
