for example, TM statuses of priority 1 and 3 are detected, the message of priority 1 will be displayed.)

Message
Priority
Description
Disable — The port connected to the TM printer is disabled. Set to Enabled using BIOS setup.
No communications — This message is displayed when a TM printer that does not have the ID function
(ESC/POS
GS I command) is connected. Check that the TM printer’s DIP switches
are set to the following.
Baud rate:
9600 bps
Word length: 8 bits
Parity: None
If DIP switches are set correctly, the device self-diagnostic utility can communicate
with the TM printer even though the message is displayed. If any abnormality is
detected, examine the check items specified in this column.
When a TM printer that has the ID function (ESC/POS
GS I command) is connected,
the device self-diagnostic utility cannot communicate with the TM printer for some
reason.
Check the following items.
❑
Are the interface cable and power cable connected to the TM printer
correctly? Before connecting the cables, be sure to power off the IR-320.
❑
Is the printer's power switch on?
❑
Is the TM printer connected to the port selected at startup of the device
self-diagnostic utility?
❑
Is the self-test for the TM printer not executed at start-up of the device
self-diagnostic utility? (Do not execute the self-test.)
❑
Is the paper FEED switch not pressed at start-up of the device self-diagnostic
utility? (Do not press the paper FEED switch.)
If the TM printer does not meet these conditions, correct the problem, and then
select the Initialize option from the menu bar.
If all the above conditions are satisfied, probable causes are the following.
