Title: INK DELIVERY SYSTEM
Abstract:
An ink delivery system includes a first tank including a fill sensor; a second tank including a fill sensor; a pump configured to pump ink from the first tank to the second tank; a third tank including a fill sensor; a print head in fluid communication with the second tank and the third tank. In an embodiment, the third tank is in fluid communication with the first tank and may be configured to provide a closed loop system, the second tank is in fluid communication with the third tank, and a pressure differential across the print head causes ink to flow through the print head. For some embodiments, pumps may be provided to control pressure differentials and print heads may print at one or more angles.
