Abstract
A method of dispensing liquid includes providing a carrier liquid under pressure using a first liquid supply that flows from the first liquid supply through a first liquid supply channel through a liquid dispensing channel through a liquid return channel and back to the first liquid supply continuously during a drop dispensing operation. A functional liquid is provided to the liquid dispensing channel through a second liquid supply channel using a second liquid supply. A drop formation device is selectively actuated to form a discrete drop of the functional liquid in the carrier liquid flowing through the liquid dispensing channel. The functional liquid is immiscible in the carrier liquid. The drop ejection device is selectively actuated to divert the discrete drop of the functional liquid and a portion of the carrier liquid flowing through the liquid dispensing channel toward an outlet opening of the liquid dispensing channel.
