摘要： A laser imaging device is described. The laser imaging device includes a first laser, a second laser, and a controller. The first laser provides a first scan line having a first starting point, and the second laser provides a second scan line having a second starting point based on an adjusted beam detect signal. The controller is configured to generate the adjusted beam detect signal using a delay code and a beam detect signal associated with the second laser to substantially horizontally align the second starting point with the first starting point.

摘要： An edge detection apparatus for detecting an edge on a surface. The apparatus comprises a source of coherent radiation for generating a radiation beam and directing the beam onto the surface. A radiation detector is located so as to detect radiation diffusely reflected, but not specularly reflected, from the surface. A system is provided for causing relative scanning movement between the radiation beam and the surface. A monitor is coupled to the detector for monitoring the intensity of the detected radiation.

摘要： A method of adjusting print uniformity in a xerographic device is provided. The method includes: a) printing a test pattern, b) transferring the printed test pattern to a scanner, c) scanning the printed test pattern and detecting line information, d) communicating the detected information to a computer, e) determining measurements from the detected line information, f) calculating the difference between the measurements and target values, and g) depending on the difference, adjusting a current supplied to an individual LED of an LED printbar associated with the measurement to reduce the difference. In one aspect, a test pattern line is associated with an individual LED. In another aspect, test pattern lines are associated with two adjacent LEDs and three adjacent LEDs.

摘要： A printing apparatus (100) for printing digital images onto a photosensitive medium (140) employing, for exposure energy, a light source (20) that uses various arrays of LEDs (32). The printing apparatus (100) may form the print image using sequential modulation, one color at a time, or by applying all colors simultaneously. Arrangements of discrete LEDs (32) may include high-intensity devices configured with collector cones (41) arranged as a multicone structure (141), with parabolic reflectors (65), or collimating lenses (36). Large area LEDs (46) may alternately be used, arranged on an angled mounting surface (64), for example.

摘要： The timing sensors provided in the light-receiving part of a beam-detecting unit have different lengths in the sub-scanning direction. The beam-passing position sensors provided in the light-receiving part of the beam-detecting unit are longer than the timing sensors, in the sub-scanning direction. The intensity of a light beam is controlled in a reference-pitch measuring routine.
