PROBLEM TO BE SOLVED: To maintain an ejected ink drop volume to be a predetermined value in a continuous ink jet printer. SOLUTION: An ink parameter, for example, temperature, velocity, flow rate or viscosity is monitored in the printer. A time period between activation control signals supplied to an ink drop forming mechanism is varied in response to a change in the ink parameter. The apparatus includes an ink parameter monitoring device which supplies an input signal to a controller. The controller varies the time period between activation control signalsΔt provided to the ink drop forming mechanism. COPYRIGHT: (C)2004,JPO
