METHOD AND APPARATUS TO REGULATE TEMPERATURE OF PRINTHEADS
摘要
<p>An apparatus including an analog memory, a temperature sensor, a comparator, and a pulse circuit. The analog memory is charged to a reference voltage corresponding to a predetermined temperature of a printhead. The temperature sensor measures a thermal voltage of at least one of the plurality of local areas of the printhead. The comparator obtains a comparison result by comparing the reference voltage to the thermal voltage. The pulse circuit selectively transmits a series of warming pulses to the at least one of the plurality of local areas of the printhead based on the comparison result.</p>
