Abstract: A cap 41 is used for nozzle inspections for clogging on the basis of a waveform of an output signal at a print head 24 when, in a state in which a potential difference has been generated among the print head 24, a regulating member 143 that is the opposing electrode opposite to the print head 24, or an ink-absorbing member 142, an operation is performed of ejecting ink from the nozzles 23 of the print head 24 to an opposing electrode. The cap 41 comprises a box member 141 in which the regulating member 143 and the ink-absorbing member 142 are contained and an electrode pin 145 that penetrates the box member 141 in a liquid-tight manner, and that is electrically connected with the regulating member 143. Thus, even when ink accumulates in the box member 141 after a nozzle inspection for clogging has taken place, no ink will leak from the part that the electrode pin 145 penetrates.

Abstract: The invention provides a method for flushing a liquid ejecting apparatus by ejecting liquid from a nozzle of a liquid ejecting head toward a liquid catcher that is provided opposite to a nozzle opening surface of the liquid ejecting head. The method comprises applying an electric field between the nozzle opening surface and the liquid catcher, ejecting the liquid from the nozzle toward the liquid catcher, detecting a change in voltage that is attributable to electrostatic induction generated when the liquid is ejected toward the liquid catcher, and determining whether to continue or discontinue the ejection of the liquid based on the change in voltage.

Abstract: A fluid ejecting apparatus that ejects fluid includes: a head capable of performing effective discharge processing, in which the head discharges the fluid toward a processing object arranged at a predetermined position, and pre-discharge processing, in which the head discharges the fluid independently of the effective discharge processing; a carriage that carries the head and adjusts a position where the head discharges the fluid; a moisture retention head cap unit that covers a discharging surface of the head; a pre-discharge reservoir that receives the fluid discharged from the head when the head performs the pre-discharge processing; and an opening cap portion configured to cover an opening formed in the pre-discharge reservoir for receiving the fluid, when the moisture retention head cap unit covers the discharging surface.

Abstract: A fluid ejecting apparatus for ejecting fluid includes a head capable of performing effective discharge during which the fluid is discharged to an object to be processed disposed at a predetermined position and capable of preliminary discharge during which the fluid is discharged separately from the effective discharge, a first head capping unit for preliminary discharge covering the head and receiving the fluid discharged from the head while the head performs the preliminary discharge, and a second head capping unit for moisturizing covering the head and moisturizing the head. The first head capping unit and the second head capping unit are stacked in such a manner that the second head capping unit covers both the head and an opening of the first head capping unit for receiving the fluid while the head does not perform either the effective discharge or the preliminary discharge.

Abstract: A liquid discharging apparatus, which discharges liquid from a nozzle of a liquid discharging head on the basis of data, includes a controller and a member. When the controller is in a standby state where the liquid is not discharged from the nozzle on the basis of the data or after the controller has received a power OFF instruction, the controller performs a drawing operation in which the liquid is drawn to a side opposite to a discharge direction in which the liquid is discharged so as to at least form a space at a distal end portion of the nozzle. After the controller has performed the drawing operation, the member covers an opening of the nozzle.
