Fixed full width array scan head calibration apparatus

摘要: An input scanner provided with a document input, sheet feeding path for transporting documents to scanning station and output; having first element, fixed in position relative the path, second arranged at home substantially simultaneous duplex of sheets fed along which is also supported movement past platen, each element supporting full width array photosensitive sensors corresponding optical arrangement directing light from sensors, there dual purpose calibration/baffle member, serves as paper baffle support position, supports calibration target detection by element. The member mounted on frame between positions, bias biases operation position. engagement therewith move
