Application: Liquid ejecting apparatus, imprint apparatus, and control method (Patent ID: US20240198679A1)
The liquid ejecting apparatus described in the patent by Canon Inc. includes an ejection unit with an orifice, an oscillating element, a retention member, a detection unit, and a control unit. The control unit is responsible for driving the oscillating element at a specific period for cleaning the orifice while liquid is retained between the retention member and the ejection surface. Additionally, the control unit can identify the natural period of the oscillating element and adjust the drive period accordingly.
Furthermore, the patent includes claims related to the configuration of the liquid ejecting apparatus, such as the use of piezoelectric elements, drive signal waveforms, collection containers for retained liquid, and circulation units for liquid circulation. The apparatus can be part of an imprint apparatus for performing an imprint process on a substrate. The method of controlling the liquid ejecting apparatus involves detecting the oscillation characteristic of the oscillating element and adjusting the drive period for cleaning the orifice based on the detection result.
