General Procedures/Information

GP 14 Image Transfer

Overview
• Image transfer is the process of transferring the toner image created on the Drum in the devel-
oping process to paper.
• Bias transfer Roll (BTR) is used instead of corona image transfer as the image transfer method.
• In BTR, there is little generation of ozone due to corona discharge. Also, there is no blur of
toner because the paper is always pressed by the Drum and the BTR.
• When cleaning the BTR and before printing, reverse bias is applied.
• The residual electric potential on the paper is dissipated via a discharge needle.
