ABSTRACT:
An apparatus for printing images on sheet material has a housing, a roller platen mounted within the housing for supporting the sheet material, and a print head mounted adjacent to the platen for receiving the sheet material between the platen and the print head and printing images onto the sheet material passed between the platen and the print head. Two first wiper-blade assemblies are mounted on either side of the roller platen relative to each other, and each wiper-blade assembly has at least one wiper blade extending across the width of the :sheet material defining an edge portion contacting the sheet material, for continuously removing dust particles and other debris from the sheet material prior to passage between the print head and the roller platen. A donor web bearing printing ink is interposed between the print head and the sheet material for forming graphic images on the sheet material by transfer of ink from the donor web to the sheet material. Two second wiper-blade assemblies are mounted on opposite sides of the print head relative to each other, and each second wiper-blade assembly includes a wiper blade defining an edge portion contacting the surface of the donor web facing the print head, for removing dust particles and other debris from the surface of the donor web prior to passage between the print head and the roller platen.
