Application: Liquid ejecting apparatus and print head (Patent ID: US20240198663A1)
The liquid ejecting apparatus described in the patent includes multiple ejection sections, each with a piezoelectric element and pressure chamber for ejecting liquid. A detection section monitors the potential of the piezoelectric element, and a determination section assesses the ejection state based on the detection result using different determination modes depending on whether the second piezoelectric element is active or not. The apparatus ensures accurate ejection control and maintenance of the ejection state.
Additionally, the print head version of the apparatus maintains similar features with multiple ejection sections, detection of piezoelectric element potential, and determination of ejection state using different modes based on the activity of the second piezoelectric element. The apparatus is designed to prioritize the determination mode based on specific signals and comparison with reference values, ensuring efficient and reliable liquid ejection in printing applications.
