2.2.7.6 Printhead Software Control

During operation at 900 PPS, one print cycle is performed at each phase switching step to meet the specifica-
tions of the printhead (solenoid drive frequency: 900 Hz).
The drive pulse width is adjusted by using an A/D converter to detect the drive voltage, and is kept within the
area shown by the oblique lines in Figure 2-55.
