(54) | LIQUID EJECTING APPARATUS AND METHOD OF REDUCING PRESSURE |
(57) A liquid ejecting apparatus includes an ejecting portion configured to eject a liquid;
a liquid channel extending from a liquid reservoir to the ejecting portion; a liquid
holder configured to hold the liquid supplied from the liquid reservoir and allow
the liquid to be supplied to the ejecting portion; a liquid driving portion configured
to cause the liquid in the liquid channel to flow; a liquid channel opening/closing
portion configured to open and close the liquid channel; a circulation channel for
the liquid; a circulation channel opening/closing portion configured to open and close
the circulation channel; and a controller configured to control drive of the liquid
driving portion and opening/closing of the liquid channel performed by the liquid
channel opening/closing portion. The controller is further configured, when pressure
in the portion of the liquid channel between the liquid driving portion and the liquid
holder is increased by the control, to control opening/closing of the circulation
channel performed by the circulation channel opening/closing portion in such a manner
that the increased pressure is released to the liquid reservoir through the circulation
channel.
