Abstract
An apparatus has an optical scanner generating image signals, and a processor electrically connected to the optical scanner. The processor converts the electrical signals into image data. Also, a printing engine is electrically connected to the processor, and a light guide is positioned between the printing engine and the optical scanner. The optical scanner generates operating condition signals when optically scanning the light guide. The optical scanner transmits the operating condition signals to the processor, and the processor adjusts operations of the printing engine based on the operating condition signals.
