Unused nozzle arrays are purged before printing so shared liquid ejecting heads avoid medium contamination without separate head inventory.

A high-Tg fixing polymer and UV absorber improve pigment fixation, abrasion resistance, and color stability in printed records.

A corrosion-resistant conductive layer improves through-hole coverability in dense heater wiring, preventing ink-driven corrosion and unstable ejection.

Ejection velocity feedback triggers kogation removal only when needed, stabilizing print quality while preserving heater life.

Different aging voltages for new and cleaned liquid ejection heads rebuild a stable kogation state and keep ejection characteristics consistent.

Reduced-pressure ink circulation drops onto a floating body to improve degassing while limiting air re-dissolution and ejection failure.

Adjusting electrode potential after kogation removal keeps ink ejection stable despite changes in the heater surface state.

A segmented ink tank shifts liquid level between small and large sections to improve degassing while limiting re-dissolved air and nozzle clogging.

A common driving pulse synchronizes ejection and flow energy elements, shrinking circuit size while stabilizing ink ejection and reducing waste ink.

A bypass flow path and air bubble removal members deaerate coating material in the robot arm to keep nozzle ejection stable during painting.

Ink retainers, guard electrodes, and suction ducts pin ink behind the nozzles to prevent submersion and keep droplet ejection uniform.

A movable mounting interface joins ink ports and electrical terminals in one step, simplifying printhead installation and reducing mounting time.

A multi-surface common electrode and coating layer prevent ink erosion, stabilizing drive waveforms and print quality in liquid ejection heads.

Drive timing is adjusted to the number of piezoelectric elements fired together, improving current stabilization and ink ejection consistency.

A two-stage nozzle with constant then gradually widening geometry prevents meniscus breakage and bubble mixing for stable liquid ejection.

Separate piezoelectric elements for ejection and residual vibration sensing raise driving frequency and throughput in liquid ejecting heads.

Temperature-based control limits excess ink circulation to reduce heat and thickening while maintaining stable, accurate liquid ejection.
