Write to the Head Voltage Value

This operation is required after installing the "ASP C202 MAIN board", "ASP Printhead", or "ASP Printer
Mechanism" in which new printheads are already installed. This operation is necessary to correct the head
drive pulse which differs from printhead to printhead depending on the piezoelectric elements
manufactured unevenly. This program allows you to write individual head voltage value into the EEPROM
on the C202 MAIN board. A failure in executing this program will result in inferior printing. The procedure
for this operation is described below.
; Take a note of the 5 columns head VH voltage value which is stamped on the left side of the
printhead before installing the new printhead.
; "ASP Printer Mechanism" is equipped with the printhead. Do not forget to note the head VH
voltage value for the equipped printheads. The 5 columns head VH voltage value is stanpped on
label which is pasted on the printer mechanism package.
