In order to access the built-in special functions, a diagnostic panel (see Section 3.2.2
below) must be connected to the printer.
The LB12/LB15 User's Guide describes how to select and run various special functions that
adapt the printer to a specific application or environment.
This section deals with other special functions, most of which are used for testing,
calibrating and adjusting various printer functions.
The special functions available, and their performance, depend on the revision level of the
installed firmware. The output from these functions can vary in appearance and content, as
a result of changes made to the printer firmware.
Special function 2 produces a printout that includes:
•
the current firmware release
•
the special functions available and the number you should use to select them.
We advise you to run special function 2 before you try to use any of the other functions (see
the LB12/LB15 User's Guide ).
The LB12/LB15 User's Guide describes how to select and run special functions 2, 4, 60-1—
60.8, 61-1—61-12, 62-1—62-8 and 63-1—63-4 using the diagnostic panel. The LB12/LB15
User's Guide also describes how to select and run the corresponding functions when you
use the set-up panel. Of the above functions, only functions 2 and 4 are described further in
this manual. The remaining special functions (used for testing, calibrating and adjusting)
can be run only when a diagnostic panel is connected or from the host (function 1).
You can temporarily disconnect the flat cable from the set-up panel and connect the special
diagnostic panel designed for maintenance purposes (see Section 3.1 and below).
The diagnostic panel is described in the LB12/LB15 User's Guide , but further essential
information is given below.
The program checks the switch position at specific times, for example after several printed
lines, while a special function is running.
•
NORMAL position means that the printer is controlled from a host via the data com-
munication line.
•
TEST position disables the line interface. The printer is controlled from the diagnostic
panel.
