摘要： In an optical scanning system the position of a scanning beam is determined by a grating across which the beam is traced and then retraced to start again. The first grate is detected by first filtering the relatively low frequency input signals generated as the beam traces across the grating and the relatively high frequency signals generated as the beam retraces across the grating. The filter passes the low frequency signals, excludes the high frequency signals and accentuates the changes between high and low frequency signals which occur as the beam reaches either end of the grating. By applying the filtered signal to a gating arrangement, it is possible to eliminate one plurality of the signals generated as the beam falls upon the end of the grating. The remaining plurality of signals is further applied to a gate which detects the first grate signal to the exclusion of all others for providing an accurate indication of the start of scan of the optical system.

摘要： A high resolution laser printer utilizes a first cylindrical lens to focus a laser beam in the sagittal direction prior to the facets of a rotating polygon. The light reflected from the polygon is focused in the horizontal direction at the photoconductor drum of an electrophotographic process by a scan lens assembly. Following the scan lens assembly, there is a second cylindrical lens which also focuses the laser beam in the horizontal direction at the photoconductor. The first and second cylindrical lenses are positioned to eliminate errors in the facets of the polygon. Scan velocity deviations resulting from the optical design are corrected by storing correction information in a memory and using this information to vary the rate at which the laser is modulated with data.

摘要： A dual mode laser printer utilizes a program-controlled microprocessor to switch between a high resolution, slow speed mode and a low resolution, high speed mode. In the printer a laser beam is modulated at a rate which is a first division of a system clock rate. This beam is caused to focus on a recording medium and, due to a rotating multi-faceted polygon, the beam sweeps across the medium. The medium is moved according to a second division of the system clock. By means of the microprocessor, the printer can be in either: (1) the high resolution mode in which the laser beam is modulated at a high rate due to the first divided signal and the medium moves at a slow rate due to the second divided signal, or (2) the low resolution mode in which the light beam is modulated at a lower rate due to the first divided signal and the medium moves at a faster rate due to the second divided signal.

摘要： Evaluation of output-producing-asset production may be performed at least by incorporating knowledge of operators of the output-producing asset into the generation of values of performance-based metrics for the output-producing asset. Since such knowledge may be only known by the respective operators, mechanisms, such as a graphical user interface (“GUI”), may be provided by which an operator inputs such knowledge and by which such knowledge is incorporated into the generation of values of performance-based metrics for an output-producing asset. A results screen may be generated to display values of performance-based metrics in a configuration that facilitates quick and simple understanding by a decision-maker or other user on how to improve return on the investment (“ROI”) in an output-producing asset.
