Abstract: In the technology of the present disclosure, multiple nozzles included in a printing head are stably driven while disparity in the usage frequency of each nozzle is suppressed. The dot counter scans the digital halftone data in the X direction and performs accumulation-counting on the pixel value Ixy (the number of printing dots) of each pixel for each address y with the accumulation counter CntCum(y). The signal value Gxy of the corresponding pixel address (x, y) is obtained from the division pattern memory unit. The nozzle selection unit selects the nozzle to be used for forming a printing dot, based on the counted values of the accumulation counter CntCum and the signal value Gxy of the division pattern. Then, the address n of the nozzle memory corresponding to the selected nozzle to form a printing dot is determined.

Abstract: In accordance with an embodiment, an inkjet head comprises a pressure chamber, an actuator, a nozzle plate, and a head drive circuit. The pressure chamber accommodates ink. The actuator is arranged in correspondence with the pressure chamber. The nozzle plate has a nozzle communicating with the pressure chamber. The head drive circuit applies a drive pulse signal, which includes a first pulse for returning a volume of the pressure chamber after expansion, a second pulse for returning the volume of the pressure chamber after contraction, and a third pulse for returning the volume of the pressure chamber after contraction, to the actuator in such a manner that the second pulse is applied without providing a standby time before the first pulse, and the third pulse is applied without providing the standby time after the first pulse.

Abstract: A fluidic die may include a number of actuators. The number of actuators form a number of primitives. The fluidic die may include a digital-to-analog converter (DAC) to drive a number of the delay circuits. The delay circuits delay a number of activation pulses that activate the actuators associated with the primitives to reduce peak power demands of the fluidic die. A number of delay circuits may be coupled to each primitive.

Abstract: An actuator is sequentially charged with output voltage “E/2” of a voltage source and output voltage “E” of a voltage source. After the charging, “Q/2” of electric charge “Q” stored in the actuator is discharged on a path returning to the voltage source. Subsequent to the discharging, the remaining all electric charge “Q/2” stored in the actuator is discharged on a closed circuit.

Abstract: A printhead system to reduce peak energy usage may include a printhead including a plurality of primitives including nozzles. A printhead control module may control the printhead to increase printed pixel resolution and to reduce peak pixel fill density for print media. The printhead control module may further control the printhead such that all the nozzles with a same address generally disposed in a column do not fire at the same time.

Abstract: In a recording suspension period when a recording head is accelerated or decelerated in a non-recording region on a recording medium, or stops moving in the course of performing a printing process (printing job), a second driving signal is generated from a driving signal generation portion. Second vibration driving pulses of the second driving signal are applied to all piezoelectric elements, so that a vibration operation is performed without ejecting the liquid. Since a second reference potential of the second driving signal is set to be lower than a first reference potential of a first driving signal generated in a recording period as much as possible, a general potential (driving voltage) of the second driving signal is reduced, and reduce power consumption in the recording suspension period is reduced. As a result, it is possible to contribute to the power consumption saving of a printer.
