5-32
If +34 volts goes below the prescribed level during printing, the printer splits one line of printing into three-pass
printing to limit the number of pin magnets excited at the same time, thus reducing the power load. If low
voltage continues even in three-pass printing, an alarm is generated.
Figure 5.31 shows the print timing and waveforms of the head pin magnet drive current.
