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. 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 is associated with the ink for cooling the ink. The cooling cell receives current from the printer energy supply circuit as a function of energy flow to the heater chip.
