(5) Transfer
The transfer roller is composed of conductive sponge material, and is designed to get the image drum
surface and the paper in a close contact.
Paper is placed over the image drum surface, and the positive charge, opposite in polarity to that of the
toner, is applied to the paper from the reverse side.
The application of a high positive voltage from the power supply to the transfer roller causes the positive
charge inducement on the transfer roller surface, transferring the charge to the paper as it contacts the
transfer roller. The toner with negative charge is attracted to the image drum surface, and it is transferred
to the upper side of the paper due to the positive charge on the reverse side of the paper.
(6) Fusing
When the transfer is completed, the toner image is fused to the paper by heat and pressure as the paper
with unfused toner image passes between the heater roller and the back-up roller. The heater roller with
Teflon coating incorporates a 400W heater (Halogen lamp), which generates heat.
