Theory of Operation
•
Bias Transfer Roller (BTR) – The BTR is a conductive roller that receives positive
voltage from the HVPS. The BTR contacts the rear side of the Belt and applies
the positive voltage to the Belt.
•
Belt – The belt is a conductive unit that 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 Belt feeds the paper toward the Fuser.
