Abstract

Generally, methods of heat management of thermal ink jet printheads require that the entire printhead structure be heated and then maintained at the "print-ready" temperature of, for example, 45°C. If the printhead is not maintained at the desired temperature, then a certain waiting period is necessary every time the printer is called on to print. With the method below, it is not necessary to wait until the entire system is warmed up, and power can be completely cut off when no printing is carried out.
