Abstract:
1. A recording apparatus comprising: a record head which includes an outlet to eject a liquid, a pressure chamber connected to the outlet, and an actuator which is selectively switchable between a small-capacity state in which the capacity of the pressure chamber is V a head driving unit which selectively supplies, to the actuator, ejection drive signals which change the state of the actuator so that the liquid is ejected from the outlet and non-ejection drive signals by which the state of the actuator is changed from the small-capacity state to the large-capacity state and then returns to the small-capacity state, to the extent that no ejection of the liquid occurs from the outlet, wherein, the head driving unit supplies the non-ejection drive signals to the actuator within a single printing cycle, such that, within the single printing cycle, at least one of the following conditions is satisfied:
