Abstract

Official abstract text for this publication.

An ink jet printer is provided with discharge heads configured to discharge ink which is filled into a cavity from a nozzle which is linked with a cavity due to the capacity of the cavity changing according to vibrating of a vibration plate which is vibrated by a piezoelectric element, a head driver configured to drive the piezoelectric element, and a detecting section configured to detect the state of the discharge heads. The detecting section is configured to detect the state of the discharge heads within a specific period of time after driving of the piezoelectric element is stopped.

First claim

Opening claim text (preview).

What is claimed is: 1. A liquid discharge apparatus comprising: a discharge section configured to discharge a liquid which is filled into a cavity from a nozzle linked with the cavity, due to capacity of the cavity changing according to vibrating of a vibration plate which is vibrated by a piezoelectric element; a driving section configured to drive the piezoelectric element; and a detecting section configured to detect a state of the discharge section, the detecting section…
