Title: VIBRATING A DISPENSE HEAD TO MOVE FLUID
Abstract:
In an example implementation, a method of dispensing fluid from a fluid dispensing device, includes receiving a dispense head at a receiving station, and receiving a notification that a supply slot in the dispense head has been filled with fluid. The method includes vibrating the dispense head to move fluid through a microfluidic channel from the supply slot into an ejection chamber of the dispense head, and providing a dispense signal to cause an ejection mechanism disposed within the chamber to eject an amount of the fluid from the dispense head.
