ABSTRACT:
The invention is directed to an ink jet printer including a printhead and a printhead driver. The printhead includes a substrate, a nozzle plate having a plurality of ink emitting orifices, a plurality of jetting heaters on the substrate and respectively associated with the plurality of ink emitting orifices, and at least one substrate heater associated with the substrate. Each of the jetting heaters and the substrate heaters include first and second terminals. The printhead driver has a plurality of energizable outputs including at least one power line output and at least two enable line outputs. One power line output is electrically connected to a first terminal of each of a jetting heater and a substrate heater. Two of the enable line outputs are coupled to a second terminal of the jetting heater and a second terminal of the substrate heater. During energizing of the one power line output, the jetting heater and the substrate heater may be selectively actuated by selectively energizing the two enable line outputs.
