Droplet ejecting apparatus, remover deterioration determining method for droplet ejecting apparatus, and storage medium

A non-transitory storage medium storing a computer readable program for a computer in a droplet ejecting apparatus including:

• a liquid feed pump that is provided in a liquid channel between a liquid storage to store liquid and a droplet ejector to eject liquid, and feeds out the liquid in the liquid storage to the droplet ejector;
• and a remover that is located in the liquid channel and removes a foreign substance in liquid, the program causing the computer to perform:
• setting, using a pressure generator, a pressure on an upstream side in a liquid feeding direction of the remover to be higher than a pressure on a downstream side in the liquid feeding direction to form a pressure difference in a state that the liquid channel is closed;
• acquiring, from a measure, information capable of specifying a pressure or a flow rate of liquid in the liquid channel when the liquid channel is opened after the pressure difference is formed;
• and
• determining deterioration of the remover based on the acquired information.
