AI Technical Summary
The impact position of liquid ejected from a nozzle can be shifted due to the influence of air currents generated during discharge, leading to deviations in the landing position and resulting in uneven images or streaks, particularly in liquid ejection heads with large print gaps.
A liquid ejection head design that incorporates a plurality of nozzles and suction holes arranged to suck gas in a direction opposite to the liquid ejection, surrounding the nozzle row to counteract airflow interference, thereby stabilizing the landing position.
The design effectively suppresses deviations in the liquid landing position, improving image quality by canceling out airflow effects and preventing misalignment, especially in liquid ejection heads with larger print gaps.
