ABSTRACT:
In 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 at least a first scanning element, normally fixed in position relative to the sheet feeding path, and supporting a full width array of photosensitive sensors with a coresponding optical arrangement for directing light from the document to the sensors, there is provided an arrangement for bringing the optical arrangement and sensors of the scanning element to a calibration sensing position for detection of a calibration target provided in a fixed position within the input scanner, while retaining the scanning element at a fixed position relative to the sheet feeding path. The arrangement for moving the optical arrangement and sensors of the scanning element to a calibration sensing position for detection of a calibration target may also provide movement to a service position to allow access to the sensors from a position exterior to the input scanner without disassembly of the scanning head from the input scanner.
