摘要:
A pagewidth printing mechanism includes a support structure. A print media feed mechanism is arranged on the support structure to feed print media along a feed path. A pagewidth printhead assembly is mounted on the support structure to span a print media feed path. The printhead assembly includes an ink delivery cartridge mounted on the support structure to span the print media feed path. A micro-electromechanical inkjet printhead is mounted on the ink delivery cartridge to receive ink from the ink delivery cartridge. A capping mechanism is arranged on the support structure and is operable to engage the printhead to inhibit drying of ink when the printhead is not in operation. A drive mechanism is arranged on the support structure and is connected to the capping mechanism to drive the capping mechanism into and out of engagement with the printhead. The drive mechanism is engaged with the print media feed mechanism such that the capping mechanism is driven out of engagement with the print head while the print media feed mechanism is driven by the drive mechanism.
摘要:
A printhead module including at least one row of printhead nozzles, at least one row including at least one displaced row portion, the displacement of the row portion including a component in a direction normal to that of a pagewidth to be printed.
摘要:
A printhead module including at least one row that comprises a plurality of adjacent sets of n adjacent nozzles, each of the nozzles being configured to expel the ink in response to a fire signal, the printhead being configured to output ink from nozzles at a first and nth position in each set of nozzles, and then each next inward pair of nozzles in each set, until: in the event n is an even number, all of the nozzles in each set has been fired; and in the event n is an odd number, all of the nozzles but a central nozzle in each set have been fired, and then to fire the central nozzle.
摘要:
A printhead module comprising at least first and second rows of print nozzles that extend along at least part of a pagewidth to be printed, each nozzle including first circuitry of a first type and second circuitry of a second type, such that, in plan view, the first and second circuitry are generally located at opposite ends of the nozzle, wherein the nozzles are orientated such that the first circuitry of the nozzles of the first row are closer to the first circuitry of the nozzles of the second row than to the second circuitry of the nozzles of the second row.

A controller for a modular printer and image capture arrangement includes a bus. Micro-controller circuitry is connected to the bus. An input interface is connected to the bus and is configured to permit at least data from an image capture device to be written to the bus. A memory is connected to the bus and is configured to store program data and at least the image data. A printhead interface is connected to the bus and configured to permit print data to be written to a pagewidth printhead.
摘要:
A replaceable print cartridge for installation in a mobile device, the print cartridge comprising: a printhead; at least one ink reservoir; and a first integrated circuit that permanently stores an identifier that is relatively unique to that integrated circuit; such that, upon installation in the mobile device, the mobile device is able to determine the identifier.
摘要:
An integrated circuit comprising: at least one active device that outputs light during a change in state of the at least one device during operation; a clock circuit configured to output a clock signal to the at least one active device, the clock signal rate being varied so as to hinder optical detection of a pattern of the light during operation of the at least one active device.
摘要:
A system for recoding and playing an audio signal provided on a photograph. The system includes a camera having a sensing system for sensing an image and recording an audio signal and a processor for generating coded data at least partially indicative of the audio signal and causing the photograph to be printed by printing the image and the coded data. The coded data is printed in substantially the same area of the photograph as the image. The system also includes a reader having a scanner for scanning the coded data, a processor for decoding the coded data to determine the audio signal and an output for playback of the audio signal.
摘要:
A replaceable print cartridge for installation in a mobile device, the print cartridge comprising: a printhead; at least one ink reservoir; storage means configured to store data; and a data changing mechanism for changing a value of the data, the data being prevented from being changed to a value that the storage means has previously stored.
摘要:
A printer is provided comprising a pagewidth inkjet printhead for printing bi-level dots of ink onto print media at a resolution of 800 to 1600 dpi and controllers for controlling the pagewidth inkjet printhead. Each controllers comprises a buffer for receiving and storing compressed page data, first and second decoders for respectively decoding compressed contone and bi-level image planes in the received compressed page data at a resolution of up to 320 ppi in each contone plane and 320 to 1600 dpi in each bi-level plane, a half-toner/compositor for halftoning the decoded contone planes and compositing the decoded bi-level planes over the halftoned contone planes to create a composite image, and a driver for outputting the composite image to the printhead. The controller is configured to send current page data to the decoders from the buffer whilst subsequent page data is received and stored in the buffer.
