Abstract

A liquid ejecting apparatus performs a wiping process for wiping a nozzle forming face while a leaking process for leaking liquid from a plurality of nozzle groups is performed by setting a pressure difference to a second pressure difference which is smaller than a first pressure difference, after performing a discharging process for discharging liquid from a part of nozzle groups among the plurality of nozzle groups by setting the pressure difference to the first pressure difference, when a difference which is obtained by subtracting an external pressure which is a pressure in a space to which a nozzle is open from an internal pressure which is a pressure of liquid in the nozzle included in the plurality of nozzle groups which eject liquid is set to the pressure difference.
