Abstract
A commutating connector which electrically connects conductive paths of a rotating electroded donor roll to a voltage source. The connector includes a housing made of an electrically insulating material. The housing defines a chamber to receive the donor roll. An electrically conductive brush is disposed in the chamber. The brush is mounted in pressing engagement against the conductive paths on the electroded donor roll to electrically connect the voltage source to the conductive paths on the electroded donor roll. The chamber is divided by a partition into a commutating and a non-commutating area. The housing has ports for receiving air to prevent particulate matter from accumulating between the brush and donor roll.
