    Abstract: Apparatus for fusing toner material to a substrate by passing the substrate between a pair of rollers at least one of which is heated. The surface temperature of the heated roller at an area where it contacts the toner material is maintained at a substantially constant value by means of a non-contact sensor comprising a part of a control for the heated roll.

    Abstract: Xerographic plates, particularly xeroradiographic plates, suitable for soft or hard x-ray exposure require margins or edges suitable for handling and mounting. In order to fabricate such plates, it is convenient to apply a peripheral mask over the substrate during application of at least the photoconductive layer. Use of masks, however, tend to promote peripheral plate irregularities, usually because of scratches or other uneveness at or under the margin of the applied mask. Such imperfections spawn corresponding electrical field irregularities which can now be minimized or avoided altogether by grounding the margins with metal overcoats.
