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