Block Step
1 Exposure Light emission from the Pre-exposure LED removes residual
potential on the surface of the Photosensitive Drum to prevent
density unevenness.
2 Primary The surface of the Photosensitive Drum is charged to make
charging a uniform positive potential. This machine uses the Primary
Charging Assembly which indirectly gives potential from the
Charging Wire to the Photosensitive Drum.
3 Laser Emission of the laser beam forms a static latent image on the
exposure surface of the Photosensitive Drum. When the laser beam is
applied on the surface of the positively charged Photosensitive
Drum, the potential at the emitted part is reduced.
4 Developing With the magnetic, 1-component toner projection developing
method, toner that has been negatively charged by the
Developing Cylinder is attached to the latent image on the
surface of the Photosensitive Drum to make it visible.
5 Pre-transfer Toner on the Photosensitive Drum is made to be a uniform
charging potential.
6 Transfer Positive potential is applied to the Transfer Roller so that the
toner on the Photosensitive Drum is transferred on a paper.
7 Separation With the curvature separation method and the static eliminator,
the paper is separated from the Photosensitive Drum and the
ETB.
8 Fixing The toner on the paper is fused on the paper by heat and
pressure.
9 ETB The Cleaning Blade removes the residual toner attached on the
cleaning ETB.
10 Drum The Cleaning Blade removes the residual toner attached on the
cleaning Photosensitive Drum.
