Abstract
An ink-jet printer with an ink nozzle purging device includes a valve equipped in a portion of an ink supply pipe extending from a pump to a printing head unit, and an ink urging unit which has a chamber equipped in a portion of the pipe between the valve and the pump, and further has an elastic member disposed in the chamber. The member accumulates an elastic force by a pressure of the ink entering into the chamber while the pump is operated with the valve being closed, and then urges the ink toward the printing head unit when the valve is opened to release the elastic force accumulated in the elastic member.
