SERIAL NUMBER INPUT (SP5-811)
Specifying Characters
SP5-811-001 specifies the serial number. For the basic machine (the machine
without the optional controller), you use the numeric keypad. For the MFP machine
(the machine with the optional controller), you use the numeric keypad and the
optional operation panel.
BASIC MACHINE
A serial number consists of 11 characters. You can change each character by
pressing one of the first 11 keys on the numeric keypad (, , , ... , ,
). For example, when you press the key, the first character of the serial
number changes as follows: 0 → 1 → 2 → ... → 8 → 9 → A → B → ... → X → Y
→ Z. When you press the key, the second character changes likewise.
You can specify a digit ("0" to "9") or a capital letter ("A" to "Z") for the first four
characters of a serial number, and you can specify a digit in the other seven
characters (not capital letters).
MFP MACHINE
You use the numeric keypad to type numbers. In addition, you use the optional
operation panel to type other characters. When you press the "ABC" key, the
letter changes as follows: A → B → C. To input the same letter two times, for
example "AA," you press the "ABC" key, the "Space" key, and the "ABC" key. To
switch between uppercase letters and lowercase letters, press the "Shift" key.
Serial Number and NVRAM
Serial numbers are stored in the NVRAM before shipment and are not cleared. You
must specify a serial number after you replace the NVRAM.
