Erase lamp control

• The toner image on the photo conductor is transferred to the transfer belt (1st image
transfer).
The potential left on the photo conductor after the toner image is transferred is neutral-
ized by turning ON the erase lamp and any potential left on the surface of the photo con-
ductor is neutralized.
• The neutralization of any residual potential on the photo conductor helps improve clean-
ing performance of toner left on the surface of the photo conductor.

A. Erase lamp ON timing
• The erase lamp is turned ON when the photo conductor starts rotating.
B. Erase lamp OFF timing
• The erase lamp is turned OFF at timing when the surface of the photo conductor that
faces the charge corona control plate (grid mesh) as the corona charge output is turned
OFF moves past the erase lamp (that is, the erase lamp is turned OFF after all charge
left on the surface of the photo conductor is neutralized).
