摘要： A method and apparatus for judging contamination of a scanner in a device having a scanning function, such as a printer scanner, are disclosed. When a data level of a white reference panel which is scanned is above a predetermined reference level, normal scanning is performed. Otherwise, the contamination of a scanner module or the white reference panel is notified to the user. Accordingly, the user can check the scanner or the white reference panel and stable image quality can be obtained by maintaining the scanner clean.

摘要： According to a method and apparatus for detecting defective printed matter in a printing press, each pixel data of a printed matter serving as a reference is stored as reference image data. Each pixel data of printed matter serving as a test object is input as test image data. Corresponding pixel data of the reference image data and the test image data are compared with each other to detect defective printed matter. A change in tone is recognized by accumulating and comparing the reference image data and the test image data in units of predetermined areas. The reference image data is automatically updated and stored on the basis of new test image data upon recognition of the change in tone.

摘要： Disclosed is a system that accepts data, either from a facsimile scanner (132) or from a computer file (122), and allows the data to be printed before being sent to a remote facsimile device. The system reads the data (204, 206, 208), converts the data to a bit mapped raster image if necessary (210), and prints the data (228) locally before it is sent to the remote facsimile receiving device. The local print resolution for printing the data is selectable, and the system will convert the data (224) into a form suitable for printing that resolution on the local printer . If the local printer (126) can print at a higher resolution, the data is scaled to allow the printing to appear at the desired facsimile resolution to allow the user to evaluate the quality of the data prior to the data being sent.
摘要翻译：公开了一种从传真机（132）或计算机文件（122）接收数据的系统，并且允许在发送到远程传真设备之前打印数据。如果需要，系统读取数据（204,206,208），将数据转换为位映射光栅图像（210），并在将数据（228）发送到远程传真接收设备之前将其本地打印。可以选择用于打印数据的本地打印分辨率，并且系统将将数据（224）转换成适合于在本地打印机上打印该分辨率的形式。如果本地打印机（126）可以以更高分辨率打印，则数据被缩放以允许打印以期望的传真分辨率出现，以允许用户在发送数据之前评估数据的质量。

摘要： An electronic printer has a scanner for scanning the document pages of a job and converting the document images scanned to pixels, and a printer for making prints of the documents from the pixels in accordance with job programming instructions, the scanner and printer operating asynchronously with respect to one another. Proofing of one or more pages of a job is effected by interrupting the job currently being scanned by the scanner to scan the proof job while continuing printing of other jobs in the print queue and, when the proof job is ready, interrupting the job being printed to print the proof job while resuming scanning of the interrupted job.

摘要： A system for calibrating a raster input scanning device (10) for detecting an image on a preselected surface, including a linear photoelectric sensor array (40) comprising a plurality of discrete photosensitive elements arranged along a first axis for sensing and generating electrical representations of an image on a surface (42); a carriage assembly (30, 32) movable along a second axis transverse to said first axis and supporting a sensor detectable target image (12) for movement along the second axis. The sensor detectable target image includes an alignment feature (70) for use during alignment operations. A drive system (34, 36) moves the carriage assembly carrying the target image from a starting position along the second axis, and the distance traveled by the carriage assembly from the starting point until the alignment feature on said target image is sensed is measured. A y-axis comparator compares the measured distance with a y-axis reference to determine a y-axis offset value which is stored in a y-axis memory (56) as an y-axis offset value. Magnification and focus calibration are provided in similar fashion.
