Checking the Serial Port

This test is typically performed by Service or your MIS
department. To check the serial port, you perform a
"loop-back" test, which checks the port for receiving and
sending data from a host.
nContact your Service representative for the loop-back plug and
procedures.
To run the Serial Port test:
1. Connect the loop-back plug to the printer.
2. From the HDW TEST MENU, press > until you see:
Printing
Serial Port
3. Press e. You will see SENDING, and then
Fif the test is successful, you will automatically return to
the HDW TEST MENU.
Fif the test is unsuccessful, you will see:
No Data Received
PRESS A KEY
4. Press b.
If the printer fails to send or receive data, please make a note
and call Service.
