3. DRUM PROCESSES
1. Charge
In the dark the charge corona unit applies a negative charge to the drum.
The grid plate ensures the charge is applied uniformly. The charge remains
on the surface of the drum because the photoconductive drum has a high
electrical resistance in the dark.
2. Exposure
High intensity light from a fluorescent lamp is reflected from the moving
original through the fiber optic array. The charge on the drum surface is
dissipated in direct proportion to the intensity of the reflected light, thus
producing an electric latent image on the drum surface.

3. Development
The magnetic developer brush on the development roller comes in contact
with the latent image on the drum surface. Toner particles are
electrostatically attracted to the negatively charged latent image areas.
4. Pre-Transfer Lamp
The pre-transfer lamp illuminates the drum prior to image transfer. This
reduces the attraction between the toner and the drum, thus making image
transfer easier.
5. Image Transfer
Copy paper is fed to the drum surface at the proper time to align the copy
paper and the developed image on the drum surface. Then a strong negative
charge is applied to the back side of the paper. The negative charge pulls
the toner particles from the drum surface onto the paper.
6. Paper Separation
A strong ac corona discharge is applied to the back side of the copy paper,
reducing the charge on the paper and breaking the electrostatic attraction
between the paper and the drum. Then, the stiffness of the copy paper
causes it to separate from the drum. The pick-off pawls help to separate
paper which has low stiffness.
7. Cleaning
The cleaning blade removes any toner remaining on the drum surface.
8. Quenching
The light from the quenching lamp electrically neutralizes the surface of the
drum.
