9-3 Confidential
9.1.3 User-access to the Machine Maintenance Mode
Basically, the maintenance-mode functions listed on the previous page should be accessed by service
personnel only. However, you can allow end users to access some of these under the guidance of
service personnel (e.g., by telephone).
The user-accessible functions (codes 10, 11, 12, 53, 66, 75, 76, 80, 82, 87, 88, and 91) are shaded
in the table given on the previous page. Function code 10 accesses the firmware switches, each of
which has eight selectors. You should not allow end users to access all of those selectors, but you
can allow them to access user-accessible selectors which are shaded
in the firmware switch tables in
Appendix 4.
The service personnel should instruct end users to follow the procedure given below.
(1) Press the Menu, Black Start (Mono Start), Menu, and Black Start (Mono Start) keys in this
order.
The "MAINTENANCE 10" appears on the LCD.
TIP: For the models equipped with a numerical keypad, you may press the Menu, Black Start
(Mono Start), and 0 keys instead in the same way as conventional models. Then pressing 1 and
0 keys, for example, calls up the setting screen for Function code 10.
(2) To access Function code 10, press the OK key.
To access any other function code, call up the desired code using the
and keys or numerical
keys.
Then press the OK key.
For Function code 10, access the desired firmware switch according to the operating procedure
described in Appendix 4.
(3) To make the machine return to standby, press the Stop/Exit key. When each of the user-
accessible functions is completed, the machine automatically returns to standby.
