ABSTRACT:
In a document feeding and imaging system with a document input tray for sequentially feeding a set of plural document sheets to a document imaging station to be respectively imaged with variable image processing conditions dependent on the size of the document sheet, including a document sheet size measurement system for measuring at least one dimension of the document sheets, wherein the input tray has associated document size measurement sensors, wherein the set of documents loaded into the input tray may be a mixed size set of different sheet sizes or a set of the same sheet sizes; there is provided an operator selectable input for a mixed size set providing a mixed size set control signal which actuates a special prescan document size sensing operational mode for sensing the sheet size as the document is fed past the document imaging station without its being imaged, and then automatically re-feeding that document to the imaging station to be imaged under image processing conditions controlled by the document size signal. If there is no mixed size set control signal, there is a different operational mode assuming a set of the same sheet documents of a size indicated by the document input tray document size measurement sensors. The mixed size set control signal may also provide a user signal restricting the system to a single pre-set pair of related but different size documents.
