User-Access To The Machine Maintenance Mode - Brother MFC260C Service Manual

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.
