  • Patent number: 5348407
    Abstract: A portable ink-jet printer and sheet feeder which can be battery powered. The printer may be manually fed paper for operation independent of the sheet feeder. The printer and sheet feeder are mounted on a base and locked at 90 degrees to one another. They may then be rotated into two operating modes in which automatic sheet feeding occurs, one of which provides a straight paper feed path for relatively stiff print media and/or printing relatively dense graphics. A paper output system includes a pair of wings and a deflector which place various arches in the paper as it emerges from the printer to maintain it over the previously printed sheet to permit it to dry. The printer may be configured by driving a print carriage having an arrow thereon to different positions adjacent a menu. When the arrow is opposite a desired configuration option, the option is selected by pressing a button.
    Type: Grant

  • Patent number: 5299875
    Abstract: A passive wet paper handling system for use, preferably, with an ink jet printer. The wet paper handling system includes an edge separator extending generally upward from an output platform of the printer and inclined away from a printer paper exit slot for deflecting the leading edge of a wet media generally upward as the media exits the printer. A pair of deflector wings are also mounted on the output platform extending generally upward from the output platform and inclined away from the paper exit slot. The deflector wings are spaced apart from the paper exit slot so that the leading edge of the media first contacts the edge separator and then contacts the deflector wings.
