Latent image
Formation
Block
1 Pre-exposure
Apply the light of the pre-exposure LED to remove the
residual charge remained on the photosensitive drum
surface and prevent uneven density.
2 Primary
Charging
Charge the photosensitive drum surface to an even positive
potential. This machine uses a primary charging unit,
which applies a charging from the charging wire to the
photosensitive drum indirectly.
3 Laser Exposure Form a latent image on the photosensitive drum surface by
irradiation of laser beam.
When a laser beam is applied to the positively charged
photosensitive drum surface, the charge in the area where
the laser beam is applied decreases.
Development
Block
4 Development
Apply negatively charged toner from the developing cylinder
to the latent image on the photosensitive drum surface
and visualize it by the magnetic one-component jumping
development method.
Transfer Block 5 Pre-primary
transfer
charging
Apply a negative charge to the toner on the photosensitive
drum.
6 Primary
Transfer
Apply a positive charge from the backside of the ITB and
transfer the toner on the photosensitive drum surface to the
ITB.
7 Secondary
Transfer
Apply a negative charge from the backside of the ITB and
transfer the toner on the ITB to the paper.
8 Separation
Separate paper from the ITB by the curvature separation
method. To make it easier to separate paper from the ITB,
a negative charge is applied to the backside of the paper
according to the paper type.
Fixing Block
9 Fixing
Toner image on the paper is made to be permanent image
by heat and pressure.
ITB Cleaning
Block
10 ITB Cleaning
Remove the residual toner remained on the ITB with the
cleaning blade.
Drum
Cleaning
Block
11 Drum Cleaning
Pre-exposure
Apply the light of the drum cleaning exposure LED to remove
drum memory on the photosensitive drum surface and
prevent dirt on the photosensitive drum.
12 Drum Cleaning Remove the residual toner remained on the photosensitive
drum with the cleaning blade.
