Transfer
The transfer roller is composed of conductive sponge material and is designed to
make the EP (image) drum surface and the paper closely into contact.
Paper is placed over the EP (image) drum surface, and a positive charge, opposite in
polarity to the toner, is applied to the paper from its reverse side.
The application of a high positive voltage (+1.5 KVDC) from the Power Supply Unit
(H10 board) to the transfer roller causes the positive charge induced on the transfer
roller surface to be transferred to the paper at the contact between the transfer roller
and the paper. As a result, toner charged negative that is attracted to the EP (image)
drum surface is transferred to the upper side of the paper by the positive charge on
the lower side of the paper.
