ABSTRACT:
A thermal ink jet printhead and control arrangement therfor includes a housing defining a plurality of ink receiving and emitting chambers with each chamber extending from an aperture in the ink emitting edge of the housing into the interior thereof. A plurality of heating elements are included, one heating element positioned in each of the chambers. An electrically conductive bus positioned within the housing connects the first terminals of the heating elements together. A power source and control system are also provided. The control system is operable to connect the second terminal of a selected one of the heating elements with the power source while simultaneously connecting the second terminals of the remaining heating elements with an electrical ground so that current from the power source flows through the selected heating element and, thereafter, through the electrically conductive bus and remaining heating elements to electrical ground.
