Transfer
The transfer roller applies a positive charge to the paper, which is pressed between the transfer roller and the
photoconductor drum. Due to relative opposite polarities between the paper, from the transfer roller, and the
photoconductor drum, from the charge roller, the charge attracts the toner onto the paper.
Clean
The cleaning blade removes the toner residue from the photoconductor drum. The cycle (charge, expose,
develop, transfer, and clean) repeats until the whole image is transferred to the paper.
