A paper feed control device for controlling a paper feed level, or height, to a predetermined one by moving up and down a tray which is loaded with a stack of papers by a motor or the like. A proportional relation between the number of papers fed as counted by a paper counter and the number of encoder pulses which is associated with an amount of movement of the tray is calculated to determine how many pulses will appear before a near-paper-end condition is reached. Based on a result of the decision, the paper feed is controlled.
