time to align it with the image on the drum. The transfer bias roller applies a high positive
charge to the reverse side of the paper through the transfer belt. This positive charge pulls
the toner particles from the drum surface onto the paper while the paper is electrostatically
attracted to the transfer belt.
Separation
Paper separates from the drum as a result of the electrical attraction between the paper
and the transfer belt. Pick-off pawls [E] help separate the paper from the drum.
ID sensor
The ID sensor [F] measures the reflectivity of the pattern formed by the laser on the surface
of the drum. This output signal is used for toner supply control and also measures the drum
surface reflectivity, which is used for charge roller voltage control.
Cleaning
The drum cleaning blade [G] removes any toner remaining on the drum surface after the
image is transferred to the paper.
Quenching
The light from the quenching lamp [H] electrically neutralizes the charge on the drum
surface.
Cleaning
The 2nd drum cleaning blade [I] removes any remaining toner.
