Abstract

PURPOSE: To lessen print shift by correcting skew time on the basis of the output voltage of a type moving speed compensating circuit while sending the output of a waveform shaping circuit to respective variation compensating circuits for a voltage, type moving speed and temperature to compensate them.
CONSTITUTION: The output of waveform shaping circuit 1 is supplied to variation compensating circuits for a voltage, type moving speed and temperature and their output voltages are mixed 5 into one and sent to a print control part. Further, a scan is taken so that all lines will be interposed among pulses of signal PSE from a driving part, and skew time is taken to attain sequential excitation. This skew time uses not a reference value but a corrected value and on the basis of output Ev from type moving speed compensating circuit 4, clocks are changed to correct the skew time, so that print shift can be lessened.
