摘要： A print media handling system for a compact printer having a housing, a cut-sheet supply station, a rotatable print platen constructed and located to feed top sheets from the supply station, through a print path ingress and out a print path egress. The sheet supply station of the print media handling system is mounted for movement to and from a sheet engaging relation with respect to the print platen. A continuous print-media inlet passage extends from a location, that is spaced from the sheet supply station, to the print path ingress and an actuator is provided synchronously enable the supply station and block the continuous media inlet passage, or vice versa. A first program control effects a predetermined start-print sequence for sheet print media, a second program control effects a predetermined start-print sequence for continuous print media; and the first or second program control is selected in response to the condition of the actuator.

摘要： A sheet supply station for a compact printer of the type having a housing, a feed/transport member which is rotatably mounted within a forward portion of the housing and is adapted to sequentially move sheets from a supply location at the bottom of the housing, through the print zone and out an egress in the upper surface of the housing. The sheet supply station comprises: (a) a drawer, including a drawer face and a drawer bottom, which is constructed to support a sheet stack and slidably mounted for movement in and out of the rear wall of the printer between a withdrawn position enabling stack insertion and a closed position wherein the drawer face is approximately flush with the rear wall; (b) side guides for engaging and centering a sheet stack, which is supported on the bottom wall, during its movement into the housing from the withdrawn drawer position; and (c) an indexing wall located transverse to the drawer path to accurately position an inserted stack beneath the feed/transport member. Sheet buckling structures are provided for reliably feeding single sheets sequentially from the top of a sheet stack.

摘要： Ink jet printing apparatus having a cleaning system whereby ink is supported proximate the droplet orifices, the charge plate and/or the operative catcher surface and ultrasonic cleaning vibrations are imposed on the supported ink mass. Such cleaning can be implemented with ink cross-flowing through the print head cavity and/or in cooperation with a varying pressure differential across the charge plate, which cause ink to oscillate inwardly/outwardly within the orifices.

摘要： A printing system for printing on a print medium is disclosed. A first linehead is disposed opposite a first side of the print medium. The first linehead defines print zones where a liquid is deposited onto the first side of the print medium. A plurality of transport rollers are disposed adjacent to the second side of the print medium. At least one transport roller is aligned with one of the one or more print zones of the first linehead. A vacuum manifold is disposed opposite the second side of the print medium. The vacuum manifold is aligned with the aligned transport roller and outputs a vacuum force that operates on the second side of the print medium to deflect the print medium causing an increase in the wrap angle of the print medium around the aligned transport roller.

摘要： A printing system includes a printing station having a rotatable print member and a set of marking subsystems. In a sheet-printing mode, a media sheet is transported to the printing station where the print member is rotated to transport the sheet past the marking subsystems to form a printed image. The printed sheet is then transported to an output sheet receptacle. In a web-printing mode the print member is configured to rotate freely and a web of media is transported around the print member past the marking subsystems to form a printed image. A tensioning system is used to control the motion of the web of media.

摘要： A method for printing on a print medium is disclosed. The method includes providing a linehead defining one or more print zones and adapted to jet liquid onto the print medium. One or more vacuum transport rollers having a porous sleeve rotatable around a non-rotating core are also provided. At least one vacuum transport roller is disposed adjacent to the second side of the movable print medium, opposite the first linehead, and aligned with a print zone. The core includes a vacuum manifold that outputs a vacuum force that operates on the print medium through the porous sleeve. The print medium is moved through the printing system and a vacuum force deflects the print medium, causing an increase in a wrap angle of the print medium around the vacuum transport roller. Liquid is jetted from the linehead onto the print medium to form a print.

摘要： A system is described for tracking a position of a receiver medium as it travels along a media path. A laser provides heat to the receiver medium in a localized area sufficient to permanently alter a physical property of the receiver medium thereby forming a reference mark. A sensor at a downstream position along the media path is adapted to sense the reference mark providing a sensed signal. The sensed signal is analyzed to determine a position of the receiver medium as the receiver medium passes through the second position along the media path by detecting a position of the reference mark.
