Ink backflow has been a problem for Continuous Ink Supply System (CISS) for a long time. Daily temperature fluctuation creates air bubbles which push ink back into external reservoirs. Once air bubbles are pushed into the supply tube, it alters the ink pressure and creating a cascade of events and stops CISS from working. Ink flow damper was designed to eliminate the ink backflow using technologies used on commercial large-format printers.

Instruction:

Identify the ink intake(1) and output(4) by the arrow (2) on the top of the damper. Insert an elbow into ink intake (1) and connect the elbow to the ink source. Draw air out from the output (4) with a syringe. Ink will flow into the damper. Alternatively, ink can be added to the damper by using the priming hole (3). Once the damper is almost full, insert another elbow to the output (4) and connect it to the printer.
