ABSTRACT:
A system for controlling temperature of a fuser unit in an laser printing device, without central processor control, includes a converting circuit for generating a temperature dependent voltage indicative of a sensed temperature of a fusing unit, a determining circuit for generating one of a first reference voltage signal corresponding to a predetermined operational temperature of the fusing device and a second reference voltage signal corresponding to a predetermined standby temperature of the fusing device; and a control signal circuit for generating a control signal in response to comparisons of the temperature dependent voltage to the generated one of the first reference voltage signal and the second reference voltage signal, the control signal for enabling a heating device to heat the fuser unit.
