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
EEPROM Data copy
this copy is completed successfully, all the other adjustments
required after replacing the main board are no longer be necessary.
This must be carried out after replacing the main board to apply
settings for the target market, etc. Perform MAC address Setting if
Initial setting
necessary.
To compensate individual variability of the mechanism, write the
PG offset value adjustment PG offset values into EEPROM calculated from the result of PG
Adjustment.
To check if the access to memory cards is correctly performed.
Memory card check
This must be carried out after replacing the Printhead in order to
enter the new Printhead ID (Head ID) that reduces variation
Head ID input between Printheads.
This corrects timing of printing in the paper feeding direction.

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 using the
adjustment program, and write the initial setting information onto
the Main Board. For the procedure of MAC address setting, see
"5.2.6 MAC Address Setting" (p.217).
For the adjustment method, see "5.2.7 PG Offset Value
Adjustment" (p.219).
Save some images in a CF card, and insert it into the slot to see if
it can be correctly read.
Enter the 33-digit head ID written on the QR code label on the
Printhead. (Read the QR code label from the top left to the
