Ink jet print cartridge having active cooling cell

摘要

An ink jet print cartridge is provided for use in an ink jet printer. The cartridge comprises a printhead including a heater chip (50). The printhead is adapted to generate ink droplets in response to the heater chip receiving energy pulses from a printer energy supply circuit. A peltier effect cooling cell (70) is associated with the heater chip for cooling the heater chip. The cooling cell receives current from the printer energy supply circuit as a function of energy flow to the heater chip. <IMAGE>
