A system and method for supplying replenishment fluid to an ink tank, wherein the ink tank includes a supply line to supply ink to a nozzle and a return line to receive unused ink. The method comprises the steps of periodically using a control system to recalibrate the ink pressure along the supply line to obtain an optimal print quality; and after the ink pressure has been recalibrated, using the control system to automatically adjust a supply rate of the replenishment fluid to the ink tank, wherein the supply rate of the replenishment fluid is adjusted based on the recalibrated ink pressure.

A microfilm camera employs a reciprocating lens to optically arrest motion of documents traveling in a high-speed stream for photographic exposure onto stationary, incrementally advanced photographic film. The reciprocation of the lens is controlled by a closed loop servo system. To enhance performance of the servo system, the lens is supported by a four-bar linkage comprising relatively stiff light-weight arms interconnected by crossed leaf spring hinges.
