Abstract (en)
[origin: EP0084891A2] In a jet type printing system a plurality of ink jets are provided in line in the direction of carriage movement. The ink jets are deflected to print in a conventional manner and also pass by charging electrodes which charge individual droplets as they are broken off from the jets. The charging electrodes are provided with a charge to produce scanning transverse to the direction of carriage movement such that if no charge is provided, ink will be caught in a catcher and returned to the ink reservoir for reuse. By interlining the lines a faster more effective printing occurs. Interlining may be done in accordance with several stated methods. An alternative provides ink jets one above the other with deflection means causing deflection to occur in opposite directions so that one effectively scans up and the other scans down, this alternative preferably employing a pair of ink catchers for the respective jets.
