Abstract
Official abstract text for this publication.
A printing apparatus includes a first piezoelectric element; a first cavity; a first nozzle; a second piezoelectric element; a second cavity; a second nozzle; a drive signal generating unit that generates a drive signal; a residual vibration detecting unit that detects the first residual vibration signal and the second residual vibration signal; a discharge state determining unit that determines the state of discharge from the first nozzle from the first residual vibration signal and determines the state of discharge from the second nozzle from the second residual vibration signal; and a setting unit that sets the frequency of detection of the first residual vibration signal to be higher than the frequency of detection of the second residual vibration signal.
First claim
Opening claim text (preview).
What is claimed is: 1. A printing apparatus comprising: a first piezoelectric element; a first cavity that is filled with a first liquid, the pressure inside the first cavity being increased or decreased by displacement of the first piezoelectric element; a first nozzle that communicates with the first cavity and discharges the first liquid as a liquid drop by an increase or a decrease in the pressure inside the first cavity; a second piezoelectric element; a second cavity…
