Initialize EEPROM parameters (Function code 01, 91)
This function is used to initialize the setting values for operation parameters, user switches, and worker switches (WSW) registered in the EEPROM. Entering function code 01 initializes most EEPROM areas. Entering function code 91 initializes only the specified areas as shown in the table below.
Operating Procedure
- Press the [0], and then the [1] (or press the [9], and then the [1] as required) in the initial state of maintenance mode. For models without keypad, press the [▲] or [▼] to display “MAINTENANCE 01” (or “MAINTENANCE 91” as needed) on the LCD and press the [OK]. “PARAMETER INIT” is displayed on the LCD.
- When initializing parameters is completed, the machine returns to the initial state of maintenance mode.
Note: Function code 01 is for service personnel. Function code 91 is for user support.
