Indicators and Switches

The SEL button can change the SEL indicator’s staus. When the SEL indicator is ON,
the printer is ON.

The printer working mode can be changed with button SEL and LF among three modes
- self-test, on/off and paper feed.

Self-Test Mode

Self-Test checks the condition of the printer. If the printer prints out the Self-Test
sample correctly, the printer is working normally. If Self-Test is wrong, the printer or
power supply needs repairing. Self-Test prints out all characters in the fonts, then
prints the messages about the interface type.

1. To enter the Self-Test mode with the printer OFF, press LF button then press SEL

button. Release both buttons. The printer will enter Self-Test mode.

NOTE: There are two ways to exit the self-test mode as follows:

1. The printer will exit self-test automatically after finishing the self-test sample print out.

2. When the self test sample is being printed, it can be terminated by pressing the

SEL button. The printer will exit the self-test mode.

On\Off Mode

After applying power to the printer or being in the Self-Test mode, the printer enters On
mode and the SEL indicator lights up. Press the SEL button, SEL indicator light turns
off. Printer enters the Off mode. When the printer is in Off mode, it can not receive data.
Press SEL again. Printer re-enters the On mode.
