ABSTRACT:
An image forming apparatus is disclosed that provides dual-page copies of a document that are free of offset. The apparatus includes a fixed scale that provides a scanning start position for the first page of the document, and a movable scale that provides a scanning end position for the second page of the document. The document is placed on a document table with a first edge of the document positioned with respect to the fixed scale. An operator controls the positioning of the movable scale to indicate the second edge of the document. The copy operation is controlled based on a prescribed range for the pages of the document that is defined by the position of the fixed and movable scales.
