Setting Switches
The DIP switches, located behind the front cover, are used for three purposes:
• To set communication parameters for the RS-232C communication interface
(see the switch settings on the next page)
• To set variables for several printer functions (see the sections for the various
printer functions in “Level 1 Diagnostics” in the “Diagnostics” chapter for the
switch settings)
• To perform diagnostic tests (see the sections for the various diagnostic tests
in “Level 1 Diagnostics” in the “Diagnostics” chapter for the switch settings)
Caution: The DIP switches are set at the factory to predetermined settings and
should generally not be changed. If you must change the settings do so carefully
to avoid changing other functions.
Before changing any of the switches, first run the print test to print out the
current switch settings on the receipt. See “Testing the Printer” at the end of this
chapter for instructions on running the print test and for a sample printout.
Note: Switch 1 is shown in the Off position for reference.
