摘要：An improvement for apparatus for heat fixing a heat fusible image to a cutsheet of support material on which a xerographic powder image has been
electrostatically transferred and wherein a charging device tacks the support materialinto thermal communication with a moving preheat roll for a predetermined period, andwherein another charging device of opposite polarity produces a pretacking condition ofthe moving preheat roll, a control circuit coupled to a guide baffle feeding the supportsheet towards the preheat roll which control circuit includes a variable resistance forcontrolling a flow of charges to ground from the guide in order to minimize trail edgeflip of the support material. The underside of the guide is coated with an electricallyinsulated material while the top side is electrically coupled to control circuit. The flow ofelectrical charges from the guide varies with the particular type of stock for the supportmaterial.
