2ND TRANSFER ROLLER CLEANING
In order to remove the remaining toner on the 2nd Transfer Roller, DC
charge is applied to transfer the remaining toner on the 2nd Transfer Roller
to the Transfer Belt.
The Cleaning Blade then scrapes off the toner on the surface of the
Transfer Belt.

CHARGE NEUTRALIZATION AND SEPARATION OF PAPER
In order to remove the residual potential on the paper with the 2nd Image
transferred, the neutralization material is applied to the guide plate without
contact after the 2nd Transfer Roller.
In order to separate the paper from the Transfer Belt without fail after the
2nd Image Transfer, a Transfer Belt Separation Claw is mounted (one point.)
