1.3.8 Neutralization

In the "Neutralization" process, the charge on the paper is neutralized or removed by Detack Saw
(neutralizing plate).

Detack Saw is a metal sheet that contacts the rear side of the paper, and a negative voltage is
applied to it from HVPS. Due to the charge induced by the "2nd transfer", toner scatters onto
surrounding metal, therefore the charge is neutralized or removed.

1.3.9 Cleaning

In the "Cleaning (Belt)" process, after the toner image is transferred to paper, the toner remaining
on the belt surface is removed.

Belt Cleaner contacts the belt only at cleaning so that the toner image being formed on the
belt surface is not damaged. Contact is made by drive from IBT Retract Motor.

Toner remaining on the belt surface is scraped off by the Cleaning Blade inside the Belt
Cleaner, and toner remaining on the belt is negatively charged and then absorbed by the
positive charged brush, and collected in the Cleaner Box.

Residual toner that is not absorbed by the brush is transferred to the drum and scraped off by
the Cleaning Blade contacting the drum.
