    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 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: 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.
