Abstract: A nozzle arrangement for an inkjet printhead includes a substrate assembly incorporating an electrical drive circuitry layer and defining an ink inlet channel; a nozzle chamber structure extending from the substrate assembly and defining a nozzle chamber in fluid communication with the ink inlet channel and an ink ejection port in fluid communication with the nozzle chamber, the nozzle chamber being rectangular in plan; an anchor extending from the substrate assembly; a thermal bend actuator extending from the anchor and electrically coupled to the drive circuitry layer; and a lever arm coupled to the thermal bend actuator, pivotally supported by the substrate assembly and terminating in a paddle within the nozzle chamber. Upon receipt of a driving signal from the drive circuitry layer, the thermal bend actuator bends to induce movement of the paddle and effect ejection of ink in the nozzle chamber through the ink ejection port.

Abstract: A nozzle arrangement for an inkjet printhead. The nozzle arrangement comprises a substrate incorporating drive circuitry and defining an ink inlet channel; side walls extending from the substrate; a roof fast with the side walls and defining an ink ejection port in fluid communication with an ink chamber defined by the roof, the side walls, and the substrate, the ink chamber being in fluid communication with the ink inlet channel; an ink ejection member interposed between the ink inlet channel and the ink ejection port such that reciprocal movement of the ink ejection member causes ejection of ink from the ink ejection port; an actuator connected to the drive circuitry at a fixed end and having a free end reciprocally displaceable with respect to the substrate on receipt of an electrical signal from the drive circuitry; and a motion transmitting structure interposed between the free end of the actuator and the ink ejection member.

Abstract: A printer is provided which has a support frame having a first slot, a plate having a tab configured to slidably engage with the first slot in order to mount the plate to the support frame and a bearing positioned in a hole of the plate, and at least one elongate roller supported at a longitudinal first end by the bearing and at a longitudinal second end by the support frame. The bearing is configured to allow pivotal movement of the roller about the second end during the sliding engagement of the plate and support frame and to allow, in use, rotation of the roller for transport of print media within the printer.

Abstract: A print engine for in an inkjet printer includes a chassis; a print cartridge mounted to the chassis, the print cartridge including a wound length of print media and defining therewithin a plurality of ink reservoirs; a first motor assembly mounted to the chassis, the first motor assembly driving a roller of the print cartridge to transport the print media; a printhead assembly engaged with the print cartridge, the printhead assembly ejecting ink from the reservoirs onto the transported print media; a cutter assembly for cutting a printed length of print media from the remaining wound length; a second motor assembly mounted to the chassis, the second motor assembly driving the cutter assembly; and a capping mechanism displaceable towards and away from the printhead by a displacement mechanism, the capping mechanism including a carrier having an elongate rib positioned to abut with the printhead.

Abstract: A testing apparatus for testing integrated circuits mounted in a carrier includes a support assembly. A controller is mounted in the support assembly. The controller is programmed to process test signals from the integrated circuits. A retaining assembly is arranged on the support assembly and is configured to receive and retain the carrier during testing. A displacement mechanism is arranged on the support assembly for displacing the retaining assembly relative to the support assembly into and out of an operative condition. Testing circuitry is operatively connected to the controller and has at least test signal generation and measurement circuitry and adaptor circuitry for operative engagement with the integrated circuits being tested, the adaptor circuitry being configured to provide both a physical and an electrical interface with the integrated circuits.

Abstract: A modular printhead includes a chassis and a plurality of ink ejection printhead modules mounted to the chassis. Each printhead module includes a first molding defining a first recess. A second molding is received within the first recess and defines a second recess. An ink ejection integrated circuit (IC) is received within the second recess. A tape automated bond (TAB) film extends from the IC and across the moldings. Typically, the recesses are elongate channels.

Abstract: Provided is a wallpaper printer having a cabinet configured to receive replaceable ink reservoirs and cartridges of blank wallpaper, and a feed system defining a media path through the cabinet, the feed system having pilot guides for guiding the blank wallpaper from the cartridges past a pagewidth printhead for printing. The printer also includes a heated platen positioned in the media path downstream of the pilot guides for heating the blank wallpaper prior to printing. The printer also has a pagewidth printhead arranged in the cabinet for printing images on the blank wallpaper, and a cutter module for cutting the printed wallpaper before the feed system feeds said wallpaper into a container configured to roll the printed wallpaper into a roll for storage purposes.

Abstract: A printhead is provided having an integrated circuit having at least one row including a plurality of sets of n adjacent nozzles, each of the nozzles being configured to expel ink in response to fire signals, and a controller for supplying the fire signals to the integrated circuit such that (a) a fire signal is provided to nozzles at a first and nth position in each set of nozzles, then (b) a fire signal is provided to the next inward pair of nozzles in each set, then in the event n is an even number, (b) is repeated until all of the nozzles in each set has been fired, or in the event n is an odd number, (b) is repeated until all of the nozzles but a central nozzle in each set have been fired, and then the central nozzle is fired.

Abstract: A nozzle assembly for an inkjet printhead is disclosed. The nozzle assembly includes an inkjet nozzle having an actuator for ejecting an ink droplet from the inkjet nozzle when a resistive element of the actuator is heated by an electrical current. A drive transistor provides an energy pulse to the resistive element of the actuator, and control logic controls the drive transistor. The drive transistor and control logic are formed on a silicon substrate, and the inkjet nozzle is formed over the drive transistor and control logic.

Abstract: A camera system deblurrs an image by detecting a velocity of a camera as an image is captured by an image sensor. A processor interconnected to the image sensor and the velocity detector processes the sensed image so as to deblurr the image and output the deblurred image to a printer means.
