摘要： A monitoring system monitors a pressure wave developed in the surrounding ambient environment during inkjet droplet formation. The monitoring system uses either acoustic, ultrasonic, or other pressure wave monitoring mechanisms, such as a laser vibrometer, an ultrasonic transducer, or an accelerometer sensor, for instance, a microphone to detect droplet formation. One sensor is incorporated in the printhead itself, while others may be located externally. The monitoring system generates information used to determine current levels of printhead performance, to which the printer may respond by adjusting print modes, servicing the printhead, adjusting droplet formation, or by providing an early warning before an inkjet cartridge is completely empty. During printhead manufacturing, an array of such sensors may be used in quality assurance to determine printhead performance. An inkjet printing mechanism is also equipped for using this monitoring system, and a monitoring method is also provided.

摘要： A thermal ink jet printhead cartridge priming apparatus that includes a plurality of caps respectively associated with a plurality of printhead nozzle arrays for controllably sealing printhead nozzle arrays pursuant to engagement thereof against the printhead cartridge to surround the nozzle arrays, a plurality of vacuum conveying elements respectively associated with the caps for individually conveying priming vacuum to an associated cap, a manually actuated selector assembly for connecting a selected one of the vacuum conveying elements to a source of priming vacuum, and a source of priming vacuum spaced apart from the manually actuated selector assembly for selectively engaging the selector assembly for application of vacuum thereto. By separating the vacuum source from the selector, positive pressure is not applied to the nozzle arrays when the caps are brought into engagement with the printhead cartridges since venting is provided by the unobstructed vacuum conveying elements.

摘要： Apparatus for protecting optical elements of an optical ink drop detector that detects the presence of an ink drop in a drop detection zone, and for maintaining an aperture plate used in conjunction with the ink drop detector. The apparatus includes a movable plate having an apertured region and a non-apertured region. The plate is movable relative to the optical elements of the drop detector and is configured to have the aperture region adjacent a drop detection zone of the optical ink drop detector when in a first position and to have the non-apertured region adjacent the detection zone when in a second position. Cleaning brushes are provided for cleaning ink from the aperture region of the movable plate when the plate is moved between the first and second positions, and an enclosure is provided for enclosing the aperture region of the plate when said plate is in the second position. Thus, when the plate is in the second position, the optical elements of the optical drop detector are covered by the non-aperture region of the plate, while the apertured region of the plate is protectively contained in the enclosure.
