B-659 ABSTRACT OF THE DISCLOSURE The present invention relates to a ink supply system for a ink jet printer comprising a primary ink supply source and a secondary or temporary ink supply reservoir connected in series to a ink transfer conduit which delivers the ink upon demand to the ink jets of the print heads. The secondary ink supply reservoir comprises a thin flexible membrane which serves as the upper surface and which expands or contracts depending upon the amount of ink present in the reservoir. The presence of a proximity device senses the movement of the flexible membrane so as to monitor the quantity of ink present in the reservoir. The secondary reservoir acts as a static pressure regulator for ink entering the ink jets.
