Abstract
Illumination adjustment of LEDs is carried out prior to printing to a color thermosensitive recording paper with each thermosensitive coloring layer of yellow, magenta, and cyan. A light control circuit lights on the LEDs by one line printing period upon printing to each thermosensitive coloring layer, and makes CCD line sensors use its reflected light to image lateral edge of the color thermosensitive recording paper. Consequently, the output signal from the CCD line sensors is set within the linearity.
