Table 2-7. Functions of Components
Symbol
Name
Function
1
Toner hopper
Contains toner.
2
Toner agitation wing
Agitates the toner inside the toner hopper and
sends toner to the toner sending roller.
3
Toner sending roller
Conveys toner to the sleeve roller.
4
Sleeve Roller
Rotates the resin sleeve.
5
Resin sleeve
Conveys toner to the surface of the OPC drum.
6
Photoconductor (OPC Drum)
Creates the latent image on the surface by the
laser beam.
Develops the image by the resin sleeve and
carries the developed image to the paper
surface.
7
Toner blade
Puts toner in a thin and even layer on the resin
sleeve. Gives negative charge to toner while
the toner is passing through between the toner
blade and the resin sleeve.
8
Bias seal
Attracts, toward the sleeve roller, the toner
which did not stick to the OPC drum.
9
