  • Patent number: 7828285
    Abstract: The present invention provides a removable input tray to be used in an image forming device, such as a printer. The input tray includes a front wall with a sloped surface for sheet separation, an opening in the front wall, and a retractor pivotally mounted in the opening. The retractor is movable between a stopping position and a retracted position, the stopping position provides a stop to the leading edge of a stack of media sheets when the stack is being inserted into the input tray, and the retracted position is triggered when the input tray is fully inserted into the image forming device.

  • Patent number: 6834931
    Abstract: An inkjet waste ink handling system embodiment of the present invention includes a spittoon reservoir for collecting waste ink dropped from an inkjet printhead, and a ramp within the spittoon reservoir having an upper end that receives any ink dropped in and a lower end to which gravity conveys such ink. In this way, pillars of dried ink are prevented from accumulating.

  • Patent number: 6722802
    Abstract: A wet printed media output system in a printing mechanism including a frame is provided. The system includes an election mechanism mounted to the frame for ejecting a wet printed medium along a media path in an output direction towards an output area and a holding member mounted to the frame adjacent to the ejection mechanism. A portion of the holding member projects out of the media path at an angle to a plane defined by the output direction and a trailing edge of the medium for deviating at least a portion of the printed medium from the output direction. Furthermore, the angle is adjustable in correspondence with a character of the printed medium.

  • Patent number: 6663098
    Abstract: A kicker in a printing device is mounted adjacent to an entrance of a feed zone where a pick roller is located for picking a top sheet from an input tray in a pick process. A plurality of next-to-top sheets next to the top sheet move out of the input tray and stop approximately at the entrance of the feed zone during the pick process. The kicker includes a relatively rigid base part for kicking a first portion of the next-to-top sheets back to the input tray and a flexible top part attached to the base part for kicking a second portion of the next-to-top sheets back to the input tray.

  • Patent number: 6598955
    Abstract: A method for wiping a printhead of an inkjet printing mechanism is provided. The printhead surface defines a printhead plane. In the method, firstly a wiper is moved substantially parallel to the printhead plane for wiping a first portion of the printhead surface. After the first portion of printhead surface is wiped, the wiper is moved away from the printhead plane for wiping a second portion of the printhead surface.
