Disposable peristaltic pump assembly for facsimile printer

摘要

Facsimile transceiver apparatus for operating in both transmission and reception modes is disclosed which features a disposable ink jet printer apparatus comprising a reservoir, dual peristaltic pumps for supplying of ink to the jet for priming and purging and for supplying a vacuum to the vicinity of the orifice of the jet for catching any purged material and the jet itself is disclosed. The pumps are peristaltic pumps of the type in which resilient tubes are progressively compressed along their axial length whereby a pressure differential is produced across the ends of the tubes. A first such pump is used to provide priming and purging ink to the jet and a second is used to provide a vacuum in the vicinity of the orifice of the jet. The entire assembly is unitary and self-contained so as to be readily replaceable in the event of any difficulty with its operation or of the consumption of all the ink contained within the reservoir.
