Neutralization and Separation of Paper (De-Tack)
To neutralize the paper that has undergone the 2nd transfer process, a Charge Neutralizing
Cloth is provided for the guide plate after the 2nd Transfer Roller.

Belt Positioning Sensor
■ When development takes place in this machine, the image of each color of toner is formed
on the surface of the Transfer Belt. The leading edge of the image of each color of toner
must therefore be aligned correctly with each other on the surface of the Transfer Belt.
■ The position of the Transfer Belt is detected when the Belt Positioning Sensor (PC4)
detects detection holes provided in the Transfer Belt.
■ There are two detection holes provided in the Transfer Belt. The image write start position
is varied according to the paper size. For a paper size of A4 or smaller, the image write
start position is aligned with detection hole A. For a paper size greater than A4, detection
hole B serves as the reference for the image write start position.
