发明名称 Liquid ejecting apparatus, and method for controlling liquid ejecting apparatus
摘要 A first flushing pulse is a drive waveform for ejecting ink by displacing a meniscus onto a pressure chamber side and an ejecting side while interposing a standby position from the standby position, a second flushing pulse is a drive waveform for ejecting the ink by pushing out the meniscus onto the ejecting side, without substantially displacing the meniscus onto the pressure chamber side from the standby position, and in a flushing processing, after a first flushing processing is performed by ejecting the ink one or more times in accordance with the first flushing pulse, a second flushing processing is performed by ejecting the ink a plurality of times in accordance with the second flushing pulse.

主权项 1. A liquid ejecting apparatus comprising: a liquid ejecting head that has a pressure chamber to communicate with a nozzle, and a pressure generation unit to generate a pressure variation to liquid within the pressure chamber, and is configured to eject the liquid from the nozzle by an operation of the pressure generation unit, wherein the apparatus is configured to perform a flushing processing by driving the pressure generation unit by a first drive waveform, and a second drive waveform which is different from the first drive waveform, the first drive waveform is a drive waveform for ejecting the liquid from the nozzle by displacing a meniscus at the nozzle from a standby position, along a nozzle axis direction, from the pressure chamber side to an ejecting side which is opposite to the pressure chamber side while passing the standby position, the second drive waveform is a drive waveform for ejecting the liquid from the nozzle by pushing out the meniscus onto the ejecting side from the standby position, without substantially displacing the meniscus at the nozzle onto the pressure chamber side from the standby position, and in the flushing processing, a first flushing processing is selectively performed by applying the first drive waveform one or more times with respect to the pressure generation unit and a second flushing processing is selectively performed by applying the second drive waveform a plurality of times with respect to the pressure generation unit, wherein depending on an elapsed time from a time of finally ejecting the liquid to a determination time Ts, the apparatus is configured to select whether or not to perform the first flushing processing before the second flushing processing.
