摘要： A collimation assembly for a multi-beamed laser scanner including a collimation housing mounted to a printhead housing of the laser scanner, and at least two adjustment brackets supported on the collimation housing and located adjacent to each other in a cross-scan direction. Each of the adjustment brackets includes a mount member and a laser light source is supported within each of the mount members, each of the light sources defining a respective light beam axis. At least two collimation lenses are also provided supported on the collimation housing and intersected by one of the light beam axes. Each of the adjustment brackets is movable relative to the collimation housing in a scan direction and in the cross-scan direction to locate each of the light beam axes at a predetermined position relative to a respective collimation lens. Each of the laser light sources is additionally adjustable in the process direction, parallel to the light beam axes, to adjust the distance between the laser light sources and the collimation lenses.
摘要翻译：一种用于多光束激光扫描器的准直组件，包括安装在激光扫描器的打印头外壳上的准直外壳，以及至少两个支撑在准直壳体上的调节支架，并且在横扫扫描方向上彼此相邻。每个调节支架包括安装构件，并且激光源支撑在每个安装构件内，每个光源限定相应的光束轴线。还设置有至少两个准直透镜，其被支撑在准直壳体上并与光束轴之一相交。每个调节支架可相对于准直壳体沿扫描方向和横扫描方向移动，以将每个光束轴相对于相应的准直透镜定位在预定位置。每个激光源可以在平行于光束轴的处理方向上额外调节，以调节激光光源和准直透镜之间的距离。

摘要： The positioning of image data written along a laser beam scan path in the scan direction, e.g., the margin and/or line length is adjusted in a manner that compensates for changes in the laser beam scan path as a result of one or more operating conditions, such as changes in temperature. Further, the positioning of image data in the process direction may be adjusted in a manner that compensates for changes in the laser beam scan path as a result of the one or more operating conditions.
摘要翻译：沿着激光束扫描路径沿扫描方向写入的图像数据的定位，例如边缘和/或线长度被调整为以补偿由于一个或多个操作条件导致的激光束扫描路径的变化的方式，如温度变化。此外，作为一个或多个操作条件的结果，可以以补偿激光束扫描路径的变化的方式来调整处理方向上的图像数据的定位。

摘要： A laser scanning unit is provided. It comprises a housing; a scanning device; a pre-scan assembly generating a light beam and directing the light beam toward the scanning device; and a post-scan optical assembly receiving a scanning beam reflected from the scanning device and causing the beam to traverse a photoconductive member along a scan path. The post-scan optical assembly comprises a sensor for detecting the beam at a start-of-scan location and an end-of-scan location along the scan path.

摘要： A lens has a lens body (1), reinforcing extensions (3a, 3b) and a clear aperture (9) surrounded on top and bottom by lens body. The lens is suitable for spot scanning. The lens is made of a water absorbing material, such as most polymers, particularly acrylate polymers. Aluminum sheets as vapor barriers are attached on each side of the lens body. This results in excellent resistance to change or distortion in high humidity environments.
