Theory of Operation
Transfer (Drum ---> Paper)
The toner image formed on the Drum surface is transferred onto the surface
of the paper. The toner is transferred onto the paper in the order of Y, M, C,
and K.
■
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.
■
Transfer Unit (Belt) – The Transfer Unit 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 Unit feeds the paper
toward the direction of the Fuser.
