  • Patent number: 11214055
    Abstract: A drive circuit (100) for driving actuators of a printhead (97) from a common drive waveform has a switching circuit (32) for coupling the common drive waveform to an actuator (1,2), and a timing circuit (10) to control the switching circuit to form a drive pulse from the common drive waveform. The drive pulse is trimmed by controlling a duration (TTRIM) of a step at an intermediate level (VHOLD) in the drive pulse. This can improve the trade-off between available range of trimming and thermal efficiency because the voltage drop across the switching circuit can be reduced, compared to trimming only the height. Decoupling during a flat portion of the common drive waveform can enable the timing of the decoupling to be more relaxed compared to decoupling during a slope. Such relaxing can enable costs, complexity and thermal loading to be reduced.

  • Patent number: 10016974
    Abstract: A driver circuit for driving actuating elements for printing, has a switch for coupling a common drive signal to provide element drive pulses to drive each actuating element according to a print signal. A timing control circuit controls the switch during sloped transitions of the common drive signal, to trim an amplitude of the actuating element drive pulses according to a common offset configurable for at least two of the actuating elements in common, and according to an element specific offset, configurable for each of the actuating elements. The offsets can be dynamic or static, and some parts of the timing can be implemented in analog form. This enables more types of errors to be compensated, and can enable the element specific offset to be implemented with simpler circuitry with less heat dissipation or less space or needing less precision and thus less cost.
