2.1.1.4 Transfer Process

In the transfer system, toner image created on the PC drum through the developing process is
transferred to the paper. The roller transfer system is used for this printer.
When the paper goes through the PC drum and the transfer roller, the roller provides the paper
with positive voltage applied from the high voltage unit. Then, the toner image on the drum
transfers to the paper being attracted by the positive voltage. The needle pole located above the
roller is used to collect the remaining static electricity on the paper.
