Test apparatus for liquid drop emission apparatus

Abstract

A test apparatus for a liquid drop emission apparatus having a plurality of emission mechanisms, the emission mechanisms each having a driving element configured to emit an ink drop from a nozzle, and an application switch coupled with a driving voltage source and the driving element in series, the application switch being configured to switch a driving voltage for emission of a liquid drop between being applied and not being applied to the driving element, the test apparatus including a test switch configured to make each of the emission mechanisms output a test voltage which appears between both ends of the application switch to a test terminal, the test apparatus including a failure deciding section configured to decide whether the emission mechanism is in failure or not on the basis of the test voltage outputted to the test terminal.
