Abstract
In a printer, a paper positioning system is used to control feeding a printing medium, such as paper, through the printer. An optical encoder is used to generate analog current waveforms as the paper is fed through the printer. An integrated adjustable current to voltage converter and digital quadrature generator are used to convert waveforms received from the optical encoder into a digital form and then selectively converted to digital form for use by the paper positioning system.
