INK JET PRINTER

摘要

A continuous ink jet printer including an ink tank for holding ink, an ink nozzle in fluid communication with the ink tank for ejecting ink droplets, and a gutter for receiving, through an ink-receiving inlet thereof, ink droplets which are not used for printing. A gutter flow path starts at the ink-receiving inlet for ink that has entered the gutter through the ink-receiving inlet, and provides fluid communication to the ink tank. A return line is in fluid communication with the gutter for conveying air to enter the gutter flow path. A makeup tank is in vapor communication with the ink tank to allow air to be conveyed from the ink tank to the makeup tank. A condenser is in fluid communication with the makeup reservoir and the return line for condensing solvent.
