Abstract
A method for driving a liquid ejecting apparatus according to a thickening state of liquid in a nozzle determined by a thickening determination section. When the thickening state is a first state, a second flushing signal by which liquid is ejected from a nozzle is supplied a first number of times to the driving element without applying a micro vibration signal by which liquid is not ejected from a nozzle. When the thickening state is a second state in which viscosity of the liquid is higher than viscosity of the liquid in the first state, the second flushing signal that is different from a first flushing signal is supplied the first number of times after applying the micro vibration signal, and a first flushing signal by which liquid is ejected from a nozzle is supplied a second number of times to the driving element after applying the second flushing signals.
