2.1.3.8 (8) Detach

In the detach step, the charge on the paper is neutralized/removed. This
is done when the Detach Saw gives negative DC voltage to the back
side of the paper.


The Detach Saw receives high voltage from the HVPS.
In the 2nd Transfer step, if there is a positive charge, the toner may
scatter, resulting in a damaged image. To prevent this, the Detach
Saw removes the charge on the paper.

2.1.3.9 (9) Cleaning (Belt)

In the Cleaning (Belt) step, the belt is cleaned after the image has been
transferred onto the paper.


The belt has residual toner that was not transferred onto the paper
in the 2nd Transfer step. The residual toner is scraped off by the
Cleaning Blade (in the Belt Cleaner Assembly) which is touching the
belt. The scraped toner is transferred through the Auger High
Assembly to the Waste Toner Box.


In the Repeat step (forming a complete full-color toner image), the
toner images are transferred from the drum surface to the belt four
times. If, during these transfers, the Cleaning Blade is touching the
belt, the toner image created up to this point will be destroyed. So
the Cleaning Bade must touch (advance to) the belt only after the
complete image has been transferred onto the paper. At other
times, the Cleaning Blade must be retracted from the belt. This
Advance/Retreat switching operation is carried out by the Cleaner
Cam Solenoid.
