Abstract: A doctor blade is used to apply a powdered toner to the depleted regions of a resistive thermal transfer ribbon. The ribbon is then moved adjacent a heating electrode that passes current through a resistive substrate of the ribbon so that a transverse line on the ribbon is heated and the added toner is fused in the depleted regions of the ribbon. The heated area of the ribbon is thereafter compressed by a cold roller to provide a uniform re-inked surface. Y0978-059

Abstract: PRINT HEAD FOR HIGH RESOLUTION ELECTROTHERMAL PRINTING APPARATUS A printing apparatus employing a print head comprising a plurality of thin wire print electrodes mounted in a single plane and held in a closely-spaced row by an electrically insulating resilient material so that the wires are individually movable out of the planar alignment to a limited extent with respect to the other wires in the array. A relatively rigid backing member is provided to support the electrode array and the print head is mounted in a relatively fixed position relative to the print ribbon and a predetermined pressure is produced between the print head and the electrothermal print ribbon during printing operations.

Abstract: The formation of toner film on the photoconductor in electrophotography is reduced by adding to the developer toner a small amount of fibrillatable polytetrafluoroethylene, and working the mixture until a random network of fibers of said polytetrafluoroethylene is formed.
