EEPROM data copy
When the main board needs to be replaced, use this to copy
adjustment values stored on the old main board to the new board. If
this copy is completed successfully, all the other adjustments required
after replacing the main board are no longer be necessary.
Readout the EEPROM data from the main board before removing it.
Then replace the board with a new one, and load the EEPROM data to
the new board.

Enter the product serial number of the printer. The ID is automatically
generated and written to the main board.
• Adjustment Program
Head ID input
This must be carried out after replacing the printhead in order to enter
the new printhead ID (Head ID) that reduces variation between
printheads.
Enter the ID printed on the Head QR code label attached on the
printhead. The correction values are automatically written to the main
board.
• Adjustment Program
TOP margin adjustment
This corrects top margin of printout. A top margin adjustment pattern is printed. Examine the lines printed

offset
This resets the counter to maintain paper feed accuracy which
decreases due to paper dust.
Reset the counter to its default.
• Adjustment Program
Disenable PF deterioration
offset
When reading the counter value from the old main board is impossible
in the case of replacing the board, use this to set the counter to its
maximum value.
Set the counter to tis maximum value (10000).
