Note:
You can use the printer with sample program (written in Microsoft Visual Basic, Visual C++). The
sample program is provided separately.
3.6 Self Test
The self test lets you know if your printer is operating properly. It checks the control circuits,
printer mechanisms, print quality, control software version, and DIP switch settings.
This test is independent of any other equipment or software, so it is a good idea to run it when
you first set up the printer and if you have any trouble. If the self tests work correctly, the
problem is in the other equipment or the software, not the printer.
3.6.1 Self Test Procedure
1. Make sure the printer is turned off and the roll paper cover is closed properly.
2. While holding down the
FEED
button, turn on the printer using the switch on the front of the
printer. The self test prints the printer settings and then prints the following, cuts the paper,
and pauses. (The
PAPER OUT
light blinks.)
If you want to continue SELF-TEST printing, Please press the
FEED button.
3. Press the
FEED
button to continue printing. The printer prints a pattern using the built-in
character set.
4. The self test automatically ends and cuts the paper after printing the following:
*** completed ***
The printer is ready to receive data as soon as it completes the self test.
Note:
If you want to pause the self test manually, press the
FEED
button. Press the
FEED
button again to
continue the self test.
