    摘要: A method for determining ink drop velocity of a printhead located at a gap above a print medium. A first ink mark is printed at a first printhead velocity. A second ink mark is printed at a different (in magnitude and/or direction) second printhead velocity. The ink for the second ink mark is ejected from the printhead at the same print ejection position used for the first ink mark plus a predetermined offset distance (if any). The distance between the ink marks is measured. The ink drop velocity is calculated using the measured distance, the predetermined offset distance, the first and second printhead velocities, and the predetermined gap. In another method, an ink mark is printed, a distance is measured between the ink mark and the ink-ejection position, and the ink drop velocity is calculated using the measured distance, the printhead velocity, and the gap.

A second ink mark is printed at a different (in magnitude and/or direction) second printhead velocity. The ink for the second ink mark is ejected from the printhead at the same print ejection position used for the first ink mark plus an offset distance (if any). An optical scan of at least a portion of the print medium is generated using a non-printhead-carrier-mounted optical scanner. The distance between the ink marks is measured using the optical scan. The ink drop velocity is calculated using the measured distance, the offset distance, the first and second printhead velocities, and the gap.

    摘要: A method of imaging substance depletion detection in an imaging device. The method includes the steps of identifying a theoretical coverage of an imaging substance for a first area of a sheet of print media; determining an actual coverage of the imaging substance for the first area of the sheet of print media; comparing the theoretical coverage with the actual coverage; and determining whether a depletion of the imaging substance has occurred based on a result of the comparing step.

    摘要: Changes in the concentration of a chemical, such as a gas, are determined using a non-linear chemical sensor which is subject to shifts in calibration over time. In order to minimize errors caused by such shifts in calibration a first infrared signal (Ig(1)) is measured and using an absorption value under an assumed chemical concentration (C(1)), a zero chemical signal Io(1) is calculated using the known physical law and mathematical relation Absorption=1−Ig/Io. A second infrared signal (Ig(2)) is then measured and the absorption value is calculated using the previously calculated zero chemical signal. A second concentration (C(2)) is then determined and the change in concentration is calculated by subtracting C(2) from C(1).

    摘要: An image sensor has two or three rows of imaging elements, all the imaging elements being of the same size. This provides the rows with a native resolution. The image sensor is also provided with three shift registers. First and second shift register elements receive information from respective corresponding imaging element in a first and second row of imagining elements while shift register elements of the third shift register receive information from four imaging elements. The four imaging elements form a super-pixel, allowing the sensor to output information in a low resolution mode, as well a native and a high resolution mode.
