Method for preventing non-discharge in a liquid jet recorder and a liquid jet recorder

摘要

In a recorder having a record head which discharges liquid to record dots and which has a discharge energy generating element arranged on a substrate, a liquid discharge port arranged for the discharge energy generating element and a liquid path for supplying the liquid to the liquid discharge path, non-discharge of the liquid in the recorder is prevented by energizing the discharge energy generating element in a non-discharge condition when the recorder is powered on and/or when a predetermined waiting time has elapsed.
