摘要： There is provided a flushing method for a fluid ejecting device that prevents clogging of a nozzle by ejecting a fluid of a set number of droplets at each set time interval in a fluid ejecting process from the nozzle of a fluid ejecting head toward a fluid receiving part that is disposed to face a nozzle opening face of the fluid ejecting head in a state of non-contacting the nozzle opening face. The flushing method includes applying an electric field between the nozzle opening face and the fluid receiving part, ejecting the fluid from the fluid ejecting head toward the fluid receiving part, detecting a voltage change based on electrostatic induction that occurs at a time when the fluid is ejected toward the fluid receiving part, and changing one between the set time interval and the set number of the droplets based on the voltage change.

摘要： A liquid ejecting apparatus includes a liquid ejecting heads that ejects a liquid onto a target, a transport unit that transports the target, cap units that include caps which are provided opposite to the liquid ejecting heads with a transport path of the target interposed therebetween, and cover units that include cover members. The cap units are movable between a capping position where the caps come into contact with the liquid ejecting heads and a retreated position where the caps are separated from the liquid ejecting heads. The cover units are driven to move the cover members in association with the transport unit such that the cover members are disposed at a closing position where the caps are covered by the cover members when the target is being transported and the cover members are disposed at an opening position that does not cover the caps during a capping operation.

摘要： Ink is sucked in a first amount from recording heads by applying negative pressure of suction pumps to the recording heads in a state in which communication between the recording heads and the atmosphere is cut off by sealing the recording heads by means of caps. The ink in the caps is then discharged by causing negative pressure of the suction pumps to act in a state in which the caps are made to communicate with the atmosphere, and then wiping is effected by a wiping blade.
