Abstract
A printing machine includes a charge neutralizing system for neutralizing static charge on sheets of material fed therethrough. The charge neutralizing system includes a grounded wire (47) located in proximity to the sheets for neutralizing charge on the sheets. The charge neutralizing system further includes a grounded conductive brush (81) mounted on a sheet deflector (61) so that one end of the brush (77) contacts sheets as they traverse a first sheet feed path (71) and the other end of the brush (79) contacts sheets are they are routed by the deflector to a second alternative sheet feed path (63). The grounded brush (81) further serves to decelerate the sheet as it exits the printing machine over the second sheet feed path (63).
