ABSTRACT:
A reprographic apparatus, such as, a copier or printer is controlled by a controller including a microprocessor and a memory, the apparatus including one or more sheet trays for supplying sheets which will receive images in use of the apparatus. One or more operating parameters of the apparatus, such as the timing of sheet feeding devices, or fuser temperature, are selectively variable in accordance with differing characteristics of sheets to be used. A set of values of the operating parameters are held in the memory for each kind of sheet, and the appropriate operating parameters are set to the values derived from the memory for a given sheet type. The sheet type, and hence the operating parameters, may be set by a local or remote user of the apparatus. Alternatively, the apparatus may include means associated with at least one of the trays for recognizing sheet characteristics and setting the operating parameters accordingly.
