<p>A system for ink short protection (FIGS. 4, 6, 7, 8) for signaling to inkjet printheads (44, 46) includes a differential signaling driver (74) having a first (78) and a second terminal (80), a differential signaling receiver (76) having a first (82) and a second terminal (84), a first capacitor (86) in series between the first terminals (78, 82), a second capacitor (88) in series between the second terminals (80, 84), and circuitry (100, 102, 90, 106, 108, 112, 114, 116, 26, 62) for reducing charge accumulation on the capacitors (86, 88). A method for ink short protection and a printing mechanism (20) having such an ink short protection system (FIGS. 4, 6, 7, 8) are also provided. <IMAGE></p> |
