LIQUID EJECTING APPARATUS AND CONTROL METHOD OF LIQUID EJECTING APPARATUS

摘要

A liquid ejecting apparatus includes a liquid ejecting head, a driving signal generator which generates a micro vibration pulse, a controller which controls applying of the micro vibration pulse to a pressure generation unit, a cap which includes a sealing space not including an absorber inside, and seals a nozzle in the sealing space by being in close contact with the liquid ejecting head, and a suction unit which sucks liquid from a nozzle, in which micro vibration driving which causes liquid in the pressure chamber corresponding to a nozzle to be subjected to a micro vibration by applying at least one or more micro vibration pulses to the pressure generation unit corresponding to the nozzle in which a cleaning operation including a suction operation using the suction unit is performed is intermittently performed.

1. A liquid ejecting apparatus comprising:
a liquid ejecting head which causes a pressure change in a pressure chamber by driving a pressure generation unit, and causes liquid containing a resin to be ejected from a nozzle; a driving signal generator which generates a micro vibration pulse which causes a pressure change in liquid in the pressure chamber to an extent in which the liquid is not ejected from the nozzle by applying the micro vibration pulse to the pressure generation unit; a controller which controls applying of the micro vibration pulse to the pressure generation unit; a cap which includes a sealing space not including an absorber inside, and seals a nozzle in the sealing space by being in close contact with the liquid ejecting head; and a suction unit which sucks liquid from a nozzle by reducing a pressure in the sealed sealing space, wherein, at a time of a non-recording operation, micro vibration driving which causes liquid in the pressure chamber corresponding to a nozzle to be subjected to a micro vibration by applying at least one or more micro vibration pulses to the pressure generation unit corresponding to the nozzle in which a cleaning operation including a suction operation using the suction unit is performed is intermittently performed.
