Stencil printer with a cam baissed press roller

A printer for printing an image comprising:

• a rotatable drum comprising a hollow cylindrical support including an apertured portion which is formed with a number of apertures and a non-apertured portion, a stencil wrapped around an outer periphery of said support;
• clamp means provided on said non-apertured portion of said support for clamping one edge of said stencil wrapped around said support;
• ink roller means disposed in said support for supplying ink to said stencil via said apertured portion of said support;
• a press roller for pressing a sheet against said stencil, said press roller including a conductive material which contacts said drum when said press roller is urged against said drum;
• and
• means for urging said press roller against said drum prior to arrival of a sheet upon which an image is to be formed, such that the conductive material of said press roller dissipates any charge on at least one of the drum and the stencil, thereby preventing the sheet from adhering to said stencil as a result of a charge.
