Image Fromation Seven Stages Process

Image Formation Stage One: Conditioning(Charging)

Conditioning is to apply a uniform negative charge onto the rotating

Organic Photo-Conductor (OPC) drum surface via corona wire assembly

or primary charge roller.

Image Formation Stage Two: Writing

In this stage, the laser beam with digital signal makes contact with the

OPC drum surface. The exposed area becomes conductive and discharges the

surface charge to ground, forming a electric latent image on the drum surface.

Image Formation Stage Three: Developing

Developing is to convert the electric latent image into visible

toner image at the developing station.Toner is attracted onto the

mag sleeve magnetically from the toner hopper,and charged via friction

between the mag sleeve and the docter blade.The doctor blade also evenly

meters the toner amount on the mag sleeve.An AC/DC voltage give the

toner a negative charge bias and transfers the toner to the OPC.

Image Formation Stage Four: Transferring

The drum with toned image rotates and contacts with the media that delivered

by the delivery system at the same rate. An opposite charge is placed on the

backside of paper by the transfer roller. The charge attracts the toner from

the drum onto the media.

Image Formation Stage Five: Fusing

The media with toned image enters into the fuser section.The fuser contains

two rollers, a heated roller and pressure roller. Here the toner is adhered

to the media by heating it up and pressing it into the media, forming a

fixing image.

Image Formation Stage Six: Cleaning

After transfer, there is a little amount toner left on the drum surface due

to static charge. The remains toner is scrapped off by the wiper blade and

deposited into the waste bin.

Image Formation Stage Seven: Discharging

There is also a certain amount of charges on the drum after

transfer. A charge from PCR discharges the residual charges.
