Liquid ejecting apparatus, imprint apparatus, and control method

An imprint apparatus comprising a liquid ejecting apparatus and operable to perform an imprint process on a substrate by ejecting liquid from the liquid ejecting apparatus,

• wherein the liquid ejecting apparatus comprises:
• an ejection unit including an ejection surface in which an orifice through which a liquid is ejected is open;
• an oscillating element provided with the orifice;
• a retention member arranged opposite the ejection surface and configured to retain a liquid between the retention member and the ejection surface;
• a detection unit configured to detect an oscillation characteristic of the oscillating element;
• and
• a control unit configured to, in a case of cleaning the orifice, drive the oscillating element at a drive period based on a detection result of the detection unit in a state in which the liquid is retained between the retention member and the ejection surface.

A method of controlling a liquid ejecting apparatus including:

• an ejection unit including an ejection surface in which an orifice through which a liquid is ejected is open;
• an oscillating element provided for the orifice;
• and a retention member arranged opposite the ejection surface and configured to retain a liquid between the retention member and the ejection surface, the method comprising:
• detecting an oscillation characteristic of the oscillating element;
• and
• controlling, in a case of cleaning the orifice, driving the oscillating element at a drive period based on a detection result of the detecting in a state in which the liquid is retained between the retention member and the ejection surface.
