Setting Check Modes

Besides the ordinary print mode, the printer has a self-test mode and hexadecimal dumping
mode to check settings of the printer.

Self-test Mode

You can confirm the following printer functions by running the self-test.
• Control circuit functions
• Printer mechanism
• Print quality

Starting Self-test
Follow the steps below to run the self-test.
1
Close the roll paper cover.
2
While pressing the FEED button, turn on the printer. (Keep pressing the
FEED button until the printer starts printing.)
The printer prints current status of the printer on the roll paper.
With the LAN interface, before printing starts, it takes 6 seconds if the IP address is fixed
and 13 seconds if the IP address is obtained with the automatic setting. (It may takes longer
depending on the response time from a host.)
When the printer finishes printing the printer status, the following message is printed and
the PAPER OUT LED flashes. (The printer is now in the self-test wait mode.):
"If you want to continue SELF-TEST printing. Please press FEED button."

To begin the print test again, press the FEED button while the printer is in
the self-test wait mode.
