Since the voltage for the confirmation is output for 3 minutes, measure the TP12
on the EZJ 94 board / EZJ106 board using an oscilloscope and confirm that the
TP12 is in the range of DC 250 ± 15V.

【Waveform of charge voltage confirmation】
Charge voltage
If the charge voltage cannot be checked using this function because the IJ printer
is operating, use the following values for reference:
Charge voltage for Auto-phase : Approx. 11 V
Charge voltage for printing (least significant dot):
Charge voltage for printing (most significant dot):
However, the charge voltage for printing will vary depending on the particle use
ratio and printing conditions (character height setting and character width).
