Abstract: A liquid ejecting device includes: an ejector including: a piezoelectric element displacing corresponding to a drive signal potential; a pressure chamber changing volume corresponding to the piezoelectric element displacement; and a nozzle communicating with the pressure chamber, and ejecting liquid from the pressure chamber; and a detector detecting residual vibrations produced by the ejector after piezoelectric element displacement. The detector detects the residual vibrations in a third period when the drive signal having a drive waveform is supplied to the piezoelectric element. The drive waveform being set to a first potential in a first period, a second potential in a second period, and a third potential in the third period. The volume of the pressure chamber in the second period is smaller than the volume in the first period. The volume of the pressure chamber in the third period is larger than in the second period.

Abstract: A method for forming an ink jet printhead comprises processing an epoxy adhesive such that negative effects from physical contact with particular inks are reduced or eliminated. Conventional adhesives processed using conventional techniques are known to gain weight and squeeze out when exposed to certain inks such as ultraviolet inks, solid inks, and aqueous inks. An embodiment of the present teachings can include processing of a particular adhesive such that the resulting epoxy adhesive is suitable for printhead applications.

Abstract: An apparatus includes a pumping chamber and a descender having a first end and a second end. The first end of the descender is centered relative to the pumping chamber and defines a first fluid flow pathway between the pumping chamber and a nozzle disposed at the second end of the descender. One or more second fluid flow pathways are defined at the second end of the descender.

Abstract: A liquid ejecting apparatus is provided with a liquid chamber which communicates with a nozzle for ejecting liquid; an inflow path which is connected to the liquid chamber; a liquid supply unit which supplies the liquid to the inflow path; an outflow path which is connected to the liquid chamber, and through which the liquid is caused to flow out from the liquid chamber; a moving object which causes the liquid to be ejected from the nozzle by reciprocating toward the nozzle in the liquid chamber; and an actuator which causes the moving object to reciprocate. In an ejecting state in which liquid is continuously ejected from the nozzle due to at least reciprocating of the moving object, a flow path resistance of the outflow path is larger than that of the inflow path.
