Abstract: A method of fabricating a mounting substrate forming an ink inlet in a first layer of a first dielectric; forming contact pads on a second layer of a second dielectric; forming a slot through the second layer; forming a window through a third layer of a third dielectric; aligning and laminating the second layer to the first layer such that the ink inlet is aligned with the slot; and aligning and laminating the third layer to the second layer so the contact pads and the slot are exposed through the window; providing a printhead die having: a drop mechanism for ejecting drops; a chamber to contain ink; and adhesively bonding the printhead die to the second layer so that the printhead die is disposed within the window and an inlet feed opening of the printhead die is aligned with the slot through the second layer.

Abstract: A method of controlling a maintenance operation in an inkjet printer, the method includes detecting that ink supply connection to a printhead has been interrupted; detecting that ink supply connection to the printhead has been restored; measuring a time interval between the interruption and the restoration of the ink supply connection to the printhead; and selecting a level of the maintenance operation, depending upon a length of the time interval.

Abstract: An inkjet printhead includes a printhead die including: a mounting substrate on which the printhead die is mounted, the mounting substrate including: a base layer including a hole; an intermediate layer including: a first surface including a plurality of contact pads; a second surface opposite the first surface, the second surface being proximate the base layer; and a slot that is aligned with the hole in the base layer; and a face layer proximate the first surface of the intermediate layer, the face layer including a window, wherein the printhead die is disposed within the window such that an ink feed opening of the printhead die is in fluid communication with the slot in the intermediate layer of the mounting substrate; and a plurality of electrical interconnections connecting bond pads of the printhead die to the plurality of contact pads on the intermediate layer of the mounting substrate.

Abstract: An inkjet printing system includes an inkjet printhead including a nozzle array and an ink inlet fluidically connected to the nozzle array; a pressure regulated ink supply including: an unvented regulator chamber including: a capillary medium; and an ink outlet connected to the ink inlet of the printhead; a free ink reservoir including an ink inlet connector; and a dividing wall disposed between the regulator chamber and the free ink reservoir, the dividing wall including an ink passageway permitting ink to pass from the free ink reservoir into the regulator chamber; a carriage configured to move the printhead and the pressure regulated ink supply back and forth across a print region; a stationarily mounted main ink supply; and a flexible ink supply line connecting the main ink supply to the ink inlet connector of the free ink reservoir.

Abstract: A method of fabricating a mounting substrate for a printhead die of an inkjet printhead, the method includes: forming an ink inlet hole in a first layer of a first dielectric material; patterning a plurality of electrical contact pads on a second layer of a second dielectric material; forming a slot through the second layer; forming a window through a third layer of a third dielectric material; aligning and laminating the second layer to the first layer such that the ink inlet hole is aligned with the slot; and aligning and laminating the third layer to the second layer such that the contact pads and the slot are exposed through the window.

Abstract: A film drive gear has a thumbwheel that is rotated by a camera user and also has a shutter cam surface that rotates with the thumbwheel to reset a shutter mechanism and has a film metering cam surface that rotates with the thumbwheel to release a film metering mechanism. The shutter cam surface and the film metering cam surface are axially separated along a shaft of the film drive gear that extends outwardly from the thumbwheel. The drive gear can include a toothed sprocket that actuates a film transport mechanism such that revolution of the thumbwheel rotates the toothed sprocket and moves the photographic film a predetermined distance. The thumbwheel also can be provided with an outer circumferential surface that is coupled to an exposure counter wheel having frame index numbers such that a predetermined number of revolutions of the thumbwheel moves the exposure counter wheel by one frame index number relative to the thumbwheel.

Abstract: When an exposure counter in a single-use camera indicates that the maximum number of exposures on a roll of film in the camera have been exposed, a function of the camera such as an electronic flash capability is disabled to prevent unauthorized recycling of the camera. A reset code must be inputted to the camera to initialize the exposure counter and to enable the electronic flash capability, to permit authorized reuse of the camera with another roll of film.
