  • Patent number: 6238114
    Abstract: A print media handling system for an imaging apparatus having a media feed path includes a pair of media support members, each have a first wall defining a media contact surface and a support portion defining a media support surface. The pair of media support members are pivotally mounted to the imaging apparatus for symmetrical operation with respect to a centerline of the media feed path. The pair of media support members define a media bin for receiving printed media. The print media handling system further includes a drive system for operating the pair of media support members between a first position wherein the media support surface of the pair of support members carries a printed media sheet and a second position wherein the printed media sheet is released to fall into the media bin.

  • Patent number: 6183079
    Abstract: An ink jet printer is provided comprising a housing, an ink jet printing apparatus and a coating apparatus. The ink jet printing apparatus is located within the housing and includes an ink jet printing device capable of ejecting ink droplets onto a first side of a printing substrate which moves through the housing along a printing substrate feed path. The coating apparatus is positioned along the printing substrate feed path and spaced from the printing device. The coating apparatus applies a substantially uniform layer of coating material onto at least a portion of the first side of the printing substrate.

  • Patent number: 5810353
    Abstract: A printer has one or more stacked sheet output units on top of it for increasing the printer's output capacity. Each unit includes a housing having a diverter as does the printer. The position of each diverter is controlled by a diverter/drive mechanism in the unit stacked on top of it. In its first position, the diverter of the printer or the unit diverts a fed sheet from a substantially vertical path therein to a sheet receiving area. In its second position, the diverter allows the fed sheet to be advanced by driven rolls to the unit thereabove. The feed rolls of a unit are driven only when the diverter in each of the printer and in any unit therebeneath are in the second position.

  • Patent number: 5761565
    Abstract: A computer controlled plain paper printer and image production apparatus comprising a monochromatic, laser stimulated electrophotographic printer having an optionally coupled color ink jet printer is described. The paper medium path from the laser printer is gate controlled between a direct exit path from the laser printer and a color print path into and through the ink jet printer. Both print units produce at their respective capacities and deliver recorded text and images on a paper substrate delivered to one or more discharge trays.
