Abstract
Ink jet apparatus of the impulse type employs one or more peristaltic pumps. The pumps comprise a flexible tube extending between the ink reservoir and the jet. One tube is constricted so as to advance ink from the reservoir to the jet. Another tube is constricted so as to create a vacuum and return ink from the jet to the reservoir.
