General Description of Copying Process

(1) Charging: Applies negative charge on the
surface of the photoconductive drum.
(2) Data reading: The images on the original
are converted into electrical signals.
(3) Data writing: The electrical signals are con-
verted into light signal (laser emission)
which exposes the surface of the photo-
conductive 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.

(9) Cleaning: Scrapes off the residual toner
from the drum.
(10) Discharging: Eliminates the residual nega-
tive charge from the surface of the photo-
conductive drum.
