Abstract
A printer having holographic scanning disc for scanning the imaging beam from a laser diode across a recording member, the diode having diode biasing and modulating current inputs for modulating the diode and thereby exposing and creating images on the recording member, a heating-cooling device in heat exchange relation with the diode for controlling diode temperatures, and a current sensor for monitoring the diode biasing and modulating currents and operating the heating-cooling device to adjust diode temperatures to maintain diode temperatures within a non-mode hopping temperature range.
