Abstract:
A scan bar assembly includes a scan element including a length direction; and a motor including an axle, wherein the axle of the motor is not parallel to the length direction of the scan element.
Abstract:
An inkjet carriage printer includes a carriage for transporting an inkjet printhead in a carriage scan direction across the print region in reciprocating fashion, the carriage including an encoder sensor; a linear encoder disposed along the carriage scan direction; and a controller for controlling the motor on the basis of signals provided by the encoder sensor, the controller includes: a first motion control mode for damping carriage vibrations during a period when the carriage is in the print region; and a selectable second motion control mode for dislodging air bubbles for removal from the inkjet printhead, wherein the selectable second motion control mode is configured to decrease damping in order to set the carriage into oscillation.
Abstract:
A method of printing using a carriage with an ink container and an ejector die mounted thereon, the ink container includes a vent hole for removing air from the ink container. Air is extracted from the ink container by moving a mass within the ink container toward the vent hole, wherein said movement of the mass toward the vent hole is generated by momentum forces arising in the mass from the back and forth movement of the carriage.
Abstract:
A printer includes a carriage configured to move a printhead along a carriage scan path; a photosensor that is mounted on the carriage, the photosensor including a field of view; a light source; and a light guiding element having a first end that is aimed at a first predetermined position along a media advance path, and a second end that is aimed at a second predetermined position along the carriage scan path, wherein the carriage is movable to an edge-detection position such that the second end of the light guiding element is aimed at the field of view of the photosensor.
Abstract:
A method of making and using a printer comprising a duplexing unit that pivots along a horizontal plane for media path access. The duplexing unit does not contain any motor driven rollers for moving a media sheet therethrough. The duplexing unit's vertical axis hinge allows the duplexing unit to swing open and closed horizontally.
Abstract:
An ink tank for an inkjet printer includes a first end wall having an ink outlet port; a second end wall opposite the first end wall; a first sidewall that extends a first length from the first end wall to the second end wall; a second sidewall that extends a second length from the first end wall, wherein the second length is less than the first length; and a connecting wall that forms a recess and that connects the second end wall and the second sidewall.
Abstract:
A method of assembling a multifunction printer, the method includes providing a printing apparatus for printing on recording media, the printing apparatus including a printer chassis having a support feature for holding a component of the printing apparatus; mounting the component of the printing apparatus onto the support feature; providing a scanning apparatus for converting an image into digitized data, the scanning apparatus including a securing feature; and affixing the scanning apparatus to the printer chassis such that the securing feature of the scanning apparatus constrains a position of the component of the printing apparatus relative to the support feature of the printer chassis.
Abstract:
An inkjet printhead having arrays of nozzles wherein each of the arrays has a corresponding ink inlet. A mounting substrate includes a first face with first openings fluidly connected to corresponding ink inlets of the arrays. A second face opposed to the first face includes a plurality of second openings fluidly connected to openings of the first face. The ink outlets of the ink chambers are fluidly connected to corresponding second openings in the second face of the mounting substrate, an outer wall is disposed proximate to the plurality of inlet ports and a second outer wall is disposed opposite the first outer wall and distal to the plurality of inlet ports. Each ink chamber has a portion located proximate to the first outer wall and an outer chamber of the plurality of ink chambers has a portion located proximate to the second outer wall.
Abstract:
An inkjet printhead assembly for use in an inkjet printer, the inkjet printhead assembly includes an array of nozzles disposed along a nozzle array direction; an ink chamber including an ink outlet that is fluidly connected to the array of nozzles; and an air-permeable membrane positioned in the ink chamber at an angle that is inclined relative to the nozzle array direction.
Abstract:
A die-mount substrate for at least one inkjet printhead die, the die-mount substrate includes a die mount surface; an ink receiving surface opposite the die mount surface; at least one latchable projection extending from a first end wall which is disposed between the die mount surface and the ink receiving surface; at least one extension from a second end wall opposite the first end wall; and a plurality of ink passageways extending from the ink receiving surface to the die mount surface.
