4.1.3.1 Finding Out the Head Voltage

Normally, the head voltage is not acknowledged without removing the printhead. This program is,
however, designed to read the head voltage data stored in the EEPPROM on the main control board. This
section describes how to find out the head voltages.
1. Connect the printer and the host computer with a parallel interface cable.
2. Run the adjustment program in the host computer.
3. Input the market code. (Refer to Section 4.1.2.)
4. Move the cursor using
"Return" key, and the Adjustment & Check menu appears.
5. Move the cursor using
A4 check pattern. See the paragraph under 6.TITLE, in which the head IDs are printed in 8 digits, as
shown in the bold letters in the example below:
