Copying of the EEPROM of PU PCB.
Adjustment purpose: The above data is copied
to another PU PCB in the event that the
current PU PCB needs to be replaced due to
maintenance replacement.
Reprogramming printer serial number
recorded on PU
Adjustment Purpose: Set for a board replaced
for maintenance when it is impossible to copy
EEPROM of the PU board (I/F error etc.)
Switching between Factory mode and
Shipping mode.
Adjustment purpose: If the EEPROM of the
PU PCB cannot be copied (I/F error, etc.),
setting is made on a maintenance
replacement PCB. Since the maintenance
replacement PCB usually comes set to the
Factory mode, it needs to be set to the
Shipping mode by this function.
Rewrite of the EEPROM set values of the CU
PCB. Adjustment purpose: The EEPROM data
is rewritten to another CU PCB in the event
that the current CU PCB needs to be replaced
due to maintenance replacement.
The maintenance utility is used to perform the adjustments of "Maintenance Utility Adjustment
