Static charge controlling system and a reproduction machine having same

摘要

A static controlling system is provided for effectively and economically controlling static charge build up on a driven web member (10) moving in contact with support structures (14,16,20,23). The static controlling system (150) includes a) at least one resistive contact member (156) for contacting the surface of the driven web member, and b) a bias source coupled to the resistive contact member for biasing the resistive contact member to apply to the surface of the driven web member a neutralizing bias, having a selected polarity and potential level, thereby effectively neutralizing and controlling static charge build up on the driven web member.
