17. IMAGE TRANSFER AND PAPER SEPARATION
Image Transfer
• A charge is applied to the Image Transfer Roller to transfer the toner image formed on the
surface of the PC Drum onto the paper.
• To ensure that image transfer efficiency is stabilized, the image transfer current is auto-
matically varied according to the paper size, paper type, and the B/W ratio of the original.
• To prevent toner from sticking to the Image Transfer Roller, a negative image transfer
voltage is applied to the roller.
Paper Separation
• To neutralize any charge left on the paper, to which the image has been transferred, a
negative voltage is applied to the Charge Neutralizing Plate.
17-1. PC Drum Paper Separator Fingers
• The PC Drum Paper Separator Fingers mechanically separate paper from the surface of
the PC Drum to ensure good and positive paper separation.
