  • Patent number: 8939274
    Abstract: An envelope feeder for a printer having two aligned conveyors moving at different speeds is disclosed. An upstream conveyor moves a backwards slanted procession of envelopes having aligned upper edges onto an inline downstream conveyor that accelerates the envelopes along a curved upper edge so that by the time any single envelope arrives at the printer ingestion or feed slot, the envelope is almost completely flat yet supported upwards slightly so that the pickup roller of the printer can easily and reliably ingest the envelope for processing. Due to the speed of the downstream conveyor, envelopes are continually and reliably presented to the printer to avoid printer stalls. The configuration reduces the amount of skill and operating labor required to establish a high-speed envelope feed source for high-speed printing.

  • Patent number: 8490964
    Abstract: A sheet feeder assembly (1) includes a bottom-feed sheet feeder (3) and a delivery table (5) positioned to receive sheets from the sheet feeder and deliver the sheets one at a time to a top-feed mechanism (205) designed to feed the top sheet of a stack of sheets in a manual feed tray of a printer (7) or the like. The top-feed mechanism includes a lifting support (204) for a stack of sheets. An exit end of the delivery table rests on and moves with the lifting support and delivers sheets one at a time to the top-feed mechanism. A balance mechanism (75) reduces the effective weight of the delivery table.

  • Patent number: 8490963
    Abstract: An image forming apparatus capable of printing a non-standard size image on a sheet of a size as desired by the user as possible, and preventing stoppage of printing the image even when there is no sheet of the size desired by the user in a sheet feeder. When image data is for a non-standard size, if there is a sheet feeder accommodating recording sheets of which vertical and lateral lengths corresponding to vertical and lateral lengths represented by the image data are designated, a control unit feeds the sheets from the sheet feeding cassette. If there is no such a sheet feeder, the control unit feeds recording sheets of a free size from a manual feed tray accommodating the recording sheets of the free size.

  • Patent number: 8401456
    Abstract: A medium holding apparatus detachably is attached to a medium feeding section of an image forming apparatus. A supporting section supports the medium thereon. A side guide is mounted to the supporting section. The side guide extends in a direction parallel to a first direction in which the medium is advanced to the medium feeding section, and is movable in a second direction substantially perpendicular to the first direction. The side guide abuts the side edge of the medium to guide the medium toward the medium feeding section. A guide unit is mounted to the supporting section, and holds the medium in a gently curved position. When the medium is fed to the image forming apparatus, the guide unit guides the medium to the supporting section.
