摘要： A stable operation is realized without any malfunction of a driver even under a voltage condition that a supplied voltage is 3.3 V or lower. For this purpose, in an ink-jet printhead having an ink orifice for discharging ink, a plurality of heat generation elements for generating heat energy used to discharge ink, and an ink channel which incorporates the heat generation elements and communicates with the ink orifice, a driver for driving the heat generation elements, and a logic circuit for controlling the driver are formed on a single board. The gate oxide film thickness of an enhancement NMOS transistor which forms the driver is larger than that of an enhancement NMOS transistor which forms the logic circuit.

摘要： A printing head has a plurality of heater boards, each of which includes a shift register to which printing data and selection data for selecting preheating pulse signals are applied as inputs, a latch circuit for latching the printing data, a selection-data latch circuit for latching the selection data, a selection circuit for selecting any one of a plurality of preheating pulse signals inputted in accordance with the latched selection data, and a plurality of heating resistors driven by the printing data or preheating pulse signals. Correction data, obtained by a head correcting apparatus, for performing printing at an average density by correcting the characteristics of each heater board is stored in a memory of the printing head. A printing apparatus decides the selection data in accordance with the correction data and sets the selection data in the selection-data latch circuit.
