2.4.12 IMAGE TRANSFER AND PAPER SEPARATION

Image Transfer
This machine employs an Image Transfer Roller to transfer the image to the paper. The High Voltage
Unit applies an image transfer current to this roller. To ensure that image transfer efficiency is stabilized,
the image transfer current is automatically 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, an image transfer voltage of -975V is
applied to the roller for cleaning.
Paper Separation
To neutralize any charge left on the paper, to which the image has been transferred, the High Voltage
Unit applies a voltage of -1200V via a ground plate to the Charge Neutralizing Plate.
