Abstract
1435856 Ink-drop printers INTERNATIONAL BUSINESS MACHINES CORP 17 Sept 1974 [27 Sept 1973] 40346/74 Heading G4H In an ink jet printer, an ink drop charging signal has values chosen to correct charge induction errors (incorrect charging of a drop due to the charges on adjacent previously charged drops) and flight interaction errors (due to electrostatic repulsion between drops and aerodynamic drag reduction). The flight correction is only performed if the subject drop is charged. A clock driven counter specifies the matrix scanning order of the drops to build up a character, adjacent drops never being printed adjacent to each other to maximize in-flight distance between successive drops to reduce interaction. Information signals (supplied to a shift register and specifying for each drop whether it is to be charged or not) and the counter produce the charging signal from circuitry which can take various forms (described) variously involving read-only stores, decoders, analogue gates (with weighting) D/A converter (with appropriate gains) digital and analogue adders, and stores. This circuitry can be multiplexed between a row of ink streams each printing in two adjacent character positions along a line of print.
