3. USER-ACCESS TO THE 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 06, 09, 10, 11, 12, 25, 45, 53, 54, 80, 82, 87 and 88) 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 1.
The service personnel should instruct end users to follow the procedure given below.
(1)Press the [Menu], [Start], [Menu], and [
] buttons in this order. The "MAINTENANCE 10" appears on the LCD.
(2)Press the [
] button or [
] button several times to display the desired maintenance code on the LCD.
Then press the [Menu] button.
(3)To switch the machine back to the standby state, press the [Stop/Exit] button. When each of the user-accessible functions is completed, the machine automatically returns to the standby state.
