Abstract
A smart paper tray determines paper size to enable maximization of throughput. The width and length of paper in the paper tray is determined by detectors mounted on slides contacting edges of the paper. The detectors can be linear or rotary encoders, potentiometers, etc. The detectors provide signals to a pitch controller and/or instructor. The pitch controller controls pitch of the printing apparatus on the basis of the signals such that the pitch is maximized to enable maximum throughput of the printing apparatus. The instructor instructs an operator on the basis of the signals how to load the paper to achieve maximum throughput.
