Introduction
5. Transferring: Another thin wire electrode, the transfer corona, puts a
high electrostatic charge on the paper. This charge attracts the toner,
transferring the toner from the OPC drum to the paper.
6. Fusing: Heat and pressure rollers fuse the transferred image to the
paper.
7. Cleaning: As the OPC drum continues to turn, erase lamps remove all
residual electrostatic charge from the OPC. The cleaning unit then
removes unused toner from the OPC.
