4. Self-Test
The self-test checks whether the printer has any problems.
- Firmware version, printer configuration information, printing quality checking pattern,
and peripheral configuration information, etc.
Users cannot perform this procedure if using the printers label peel-off option.
If the printer does not function properly, contact an authorized dealer.
The self-test checks the following;
1) Make sure that the paper roll has been installed properly.
2) Turn on the power while holding down the FEED button. The self-test begins.
(It takes about 5 seconds before starting self-test)
3) The self-test prints the current printer configuration information.
4) After the self-test results are printed out, a printer enters into Print Standby Mode.
