7193 Owner’s Guide Communication
May 1996
Parallel Switch Settings
The DIP switches are not used by the Parallel interface except for selecting the
size of the data buffer and for running diagnostic tests, which must be done while
the printer is in level 1 diagnostics (setup mode) with switch 1 set to On. See
“Level 1 Diagnostics” in the “Diagnostics” chapter for more information.
When switch 1 is set to Off, the printer is on-line and ready to communicate with
the host system. Switches 2-6 are not used at any time the printer is on-line, and
they are set to Off at the factory.
Caution: The switches can also be used for setting other functions and tests. Be
careful when setting the switches for the Data Buffer settings that you do not
accidentally change the settings for the other functions and tests.
Note: The Data Buffer option is set with the printer in the setup mode. See
“Level 1 Diagnostics” in the “Diagnostics” chapter for more information.
