<Function>
This function initializes the setting values of the operation parameters, user switches, and

almost all of the EEPROM areas, but entering 91 does not initialize some areas, as listed
below.
<Operating procedure>
(1) Press the 0 and 1 keys (or the 9 and 1 keys according to your need) in this order in the
initial state of the maintenance mode. The "PARAMETER INIT" appears on the LCD.
(2) Upon completion of parameter initialization, the machine returns to the initial state of the
maintenance mode.
