When the EEPROM data copy is impossible with the main
board that needs to be replaced, the Waste Ink Pad must be
replaced after replacing the main board with a new one.
After all required adjustments are completed, use the “Final
check pattern print” function to print all adjustment patterns
for final check. If you find a problem with the printout patterns,
carry out the adjustment again.
When using a new main board for replacing the Printer
Mechanism, the Initial setting must have been made to the main
board.
