 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.
