Abstract
A reproduction machine with a paper path along which copy sheets are brought one by one into transfer relation with a photoreceptor to receive a developed image, the copy sheets being supplied from either a main or auxiliary paper tray which feeds sheets at a predetermined clock count in synchronization with the operation of the machine, a program permitting the current clock count of a selected tray to be determined and compared with a desired optimum clock count window stored in memory, with adjustment of the clock count made when the current clock count of the selected tray is outside the optimum clock count window to bring paper tray timing within the window, but prevented where the current clock count is outside preset maximum and minimum clock counts.
