Theory of Operation
■
Bias Transfer Roll (BTR) – The BTR is a conductive roll, which receives
positive voltage from the HVPS. The BTR contacts the rear side of the
Belt and applies the positive voltage to the Belt.
■
Transfer Unit (Belt) – The Transfer Unit is a conductive unit, which
receives positive voltage from the BTR. After the negative charged toner
image on the Drum surface is drawn by the positive charge on the belt, it
is transferred from the Drum to the paper. The Transfer Unit feeds the
paper toward the direction of the Fuser.
■
Electric Static Attachment (ESA) Roll – The ESA Roll is a conductive
roll, which receives positive voltage from the HVPS and discharges to the
paper to improve the toner transfer efficiency.
