Abstract
The level of ink in a reciprocating reservoir is automatically controlled for both printing and non-printing conditions. The reciprocating motion creates forces to cause the ink to move back and forth between the reciprocating reservoir and a main stationary reservoir and to maintain the ink at one level during printing. A check valve controls direction and flow of ink moving between the reservoirs and allows the ink to rise in the first-mentioned reservoir during non-printing.
