摘要： A system and method for evaluating worksheets are provided. The method includes accessing by a processor a digitally stored image of a worksheet that was administered to a student, wherein the worksheet includes the presentation of at least one problem for the student to respond to and each problem presentation includes an answer region that the student manually, mechanically, or electronically marked with an answer to the problem using a variety of alphanumeric characters. The method further includes generating expected answer data that provides an expected answer for each answer region; locating each answer region in the image; extracting from each located answer region the student's marks; processing the student's marks extracted from each answer region with character recognition processing; and storing the processed marks as student answer data. The student answer data is evaluated by comparing the student answer data with the expected answer data and generating corresponding evaluation data.

摘要： Systems and a method for image forming systems to skip over the non-printing photoreceptor area in order to not skip a label position on a continuous print web medium. A vacuum assembly is coupled to a controller that controls different vacuum pressures at each vacuum roller therein. The vacuum rollers provide drag and drive forces to skip a seam of the photoreceptor and a residual length based on the number and size of images on the photoreceptor.
摘要翻译：用于图像形成系统的系统和方法来跳过非打印感光体区域，以便不跳过连续打印网络介质上的标签位置。真空组件联接到控制器，其控制其中的每个真空辊处的不同真空压力。真空辊提供阻力和驱动力以基于感光体上的图像的数量和尺寸跳过感光体的接缝和残余长度。

摘要： A method and apparatus for lifting an elevator plate of a media tray in an image production device is disclosed. The method may include receiving a request to print a print job using stacked media from one of one or more media trays, initiating lifting of the leading edge of the elevator plate so that the stacked media may be received by the one or more feeder rollers, initiating printing of the requested print job from the one of one or more media trays, determining if the amount of stacked media in the one of the one or more media trays is less than a predetermined amount, wherein if it is determined that the amount of stacked media in the one of the one or more media trays is less than the predetermined amount, initiating lifting of both of the leading and trailing edge of the elevator plate so that the stacked media may be received by the one or more feeder rollers.
