ABSTRACT:
In a paper feed control system for a cut sheet-double side printing laser printer having a paper feed portion for stacking a plurality of paper sheets cut to a predetermined size; a paper feed mechanism for feeding the paper sheets one by one from the paper feed portion; a printing mechanism portion for printing first page data to one surface of the paper sheet, fed from the paper feed mechanism, by an electrophotographic means; and a return feed path which in order to print second page data to the other surface of the paper sheet, inverts the front and reverse surfaces of the paper sheet having the printed surface so as to selectively feed the paper sheet again to the printing mechanism portion. A plurality of feed roller mechanisms are provided which can be driven independently of one another so that the speeds of travel of a plurality of paper sheets in the feed path are changed independently of one another in accordance with the condition of the printer device or a host device.
