Abstract: The velocity of the ink droplets in an aspirated ink jet printer is maintained substantially uniform by a closed loop servo system which includes a drop charge sensor (38) and means (46) for determining the time of flight of charged droplets in the ink stream or streams. A controller (46) uses the time of flight data to generate a control voltage to adjust the speed of a blower motor (58) which supplies air to the aspirated ink jet printer.
