3.4 COPY PROCESS
3.4.1 General Description of Copying Process
Fig. 3-10
(1) Charging: Applies negative charge on the
surface of the photoconductive drum. (7) Transfer: Transfers the visible toner image
on the photoconductive drum onto paper.
(2) Original exposure: Converts images on the
original into optical signals. (8) Separation: Separates paper with the toner
image from the photoconductive drum.
(3) Data reading: The optical signals are
converted into electrical signals. (9) Fusing: Fuses the toner image onto the
paper by applying heat and pressure.
(4) Data writing: The electrical signals are
converted into light signal (laser emission)
which exposes the surface of the
photoconductive drum. (10) Cleaning: Scrapes off the residual toner
from the drum.
(5) Development: Negatively-charged toner
adheres to the photoconductive drum and
forms visible image. (11) Discharging: Eliminates the residual
negative charge from the surface of the
photoconductive drum.
(6) Transfer assist bias: Improves transfer
efficiency.
