Abstract

Special sheets to be handled differently from normal sheets are accommodated in a specific sheet feeding deck such that a predetermined operation or presentation associated with reproduction procedure is permitted or prohibited for the special sheets in the specific sheet feeding deck. For example, if the production of two-sided copies is prohibited for a specific sheet feeding deck which accommodates sheets to be used again, the sheets are not automatically selected during the production of two-sided copies even if they are of the same size as a document original. This ensures erroneous handling is prevented, such as image forming on both sides of the special sheets in the specific sheet feeding deck.
