TEST UNAVAILABLE
This message appears when you select a test on the Setup menu, but the
test is not in the installed Intelli-card.
Corrective action: Turn the Select-dial to clear the message and return
to the Setup menu. If you have an Intelli-card that provides the test you
selected, turn off the printer, install the card, turn on the printer, and retry
the test.
CONNECT LOOPBACK
When you select the Serial test on the Setup menu, this message appears
to remind you to attach a loopback connector onto the printer's serial
interface. If you perform the test without a loopback connector, the
test is invalid and fails automatically.
Corrective action: Attach a loopback connector to the serial interface;
then turn the Select-dial to start the test. The loopback connector is
described in the Interfaces appendix.
