Image Formation Process
The image formation system of the machine mainly consists of the photosensitive drum, primary charging roller, developing cylinder, transfer charging roller, static eliminator, and cleaning blade. The image formation process around the drum unit contains the six blocks.
Image Formation Process
Description
[1]
Primary charging block
Charges the surface of the photosensitive drum to a uniform negative potential.
[2]
Laser exposure block
Exposes laser beam on the surface of the drum for charge neutralization to form the latent image formation.
[3]
Developing block
Causes the negatively-charged toner on the developing cylinder to adhere to the latent image formation on the surface of the photosensitive drum to form a visible image.
[4]
Transfer block
Applies positive charge to the back of a paper to transfer the toner on the drum to the paper.
[5]
Separation block
Separates a paper from the photosensitive drum with its elastic force and at the same time applies negative charge to the back of paper to facilitate paper separation.
[6]
Drum cleaning block
Scrapes off the residual toner on the surface of the drum using the cleaning blade and feeds it to the waste toner box.
