AI Technical Summary
Liquid jet heads face challenges in maintaining ejection stability when jetting high-viscosity liquids, as existing technologies require adjustments in drive signal voltages and circuit configurations, which can be limiting and inefficient.
The liquid jet head employs a drive signal with specific pulse configurations, including expansion and contraction pulses, where the timing of volume changes in the pressure chamber is synchronized between extremal pressure values, ensuring stable ejection without the need for high drive voltages or circuit modifications, regardless of the jet head structure.
This approach ensures consistent ejection stability for high-viscosity liquids without requiring increased drive signal voltages or circuit changes, improving printing quality by preventing bubble formation and maintaining ejection characteristics.
