3.4.1 General Description of Copying Process
Fig. 3-23
(1) Charging: Applies negative charge on the
surface of the photoconductive drum.
(7) Separation: Separates paper with the toner
image from the photoconductive drum.

(2) Data reading: The images on the original
are converted into electrical signals.
(8) Fusing: Fuses the toner image onto the
paper by applying heat and pressure.

(3) Data writing: The electrical signals are
converted into light signal (laser emission)
which exposes the surface of the
photoconductive drum.
(9) Cleaning: Scrapes off the residual toner
from the drum.

(10) Discharging: Eliminates the residual
negative charge from the surface of the
photoconductive drum.

(4) Development: Negatively-charged toner
adheres to the photoconductive drum and
forms visible image.

(5) Transfer bias: Improves transfer efficiency.

(6) Transfer: Transfers the visible toner image
on the photoconductive drum onto paper.
