ABSTRACT:
In hard copy machines, automatic detection of the size of print media in a supply bin is provided by electrical devices. Adjustable print media alignment fences are operatively connected to the electrical devices, such as potentiometers, photovoltaic strips, photoemitter-photodetector arrays, or the like. The output signals from the electrical devices are correlated to width and length dimensions of the print media or the absence of print media availability. Embodiments are disclosed for standard and custom print media size detection.
