Abstract
PURPOSE: To prevent the quality of print from deteriorating by making even intervals of dots with regard to a charge control system ink jet printer, by generating charge signals that correspond to dot positions of all dots at every scanning position.
CONSTITUTION: Charge signals that correspond to dot positions of all dots at every scanning position are generated and written in storage circuit 13 by writing circuit 14 while the printer is not in print operation. Synchronizing with dot selection in the scanning direction of character pattern generator 12, charge scanning signals are read out of storage circuit 13 and converted by D-A converter 19 into analog signals, which are converted by video amplifier 20 into desired voltages before applied to charging electrodes. The charge signals written in storage circuit 13 are generated in view of influences of the size of print characters and air resistance when ink particles fly so that dot intervals will be even. Consequently, print of good quality can be attained.
