(5) Transcript
A sheet of paper is placed under the OPC drum surface and is given electric charge from
the back side by the transcript roller. When a high voltage is impressed on the transcript
roller, the electric charge generated by the transcript roller moves over to the paper surface
at the interfacing part of the transcript roller and the toner is absorbed to the paper surface
from the OPC drum surface.
