three,58mm Receipt Printertroubleshooting

If your printer malfunctions, please refer to this section for troubleshooting. If the problem persists, please contact your dealer or the manufacturer.

1. The indicator lights on the control panel are not lit.

Check that the power cord is correctly plugged into the printer, power adapter, and power outlet. Check that the printer's power switch is on.

2. The indicator lights are normal, but the printer is not printing.

Run a self-test to check if the printer is working properly. If the self-test fails, contact your dealer or technical support.

If the self-test proceeds normally, check the following:

(1) Check the interfaces at both ends of the cable connecting the printer and the computer. Also confirm that the cable meets the specifications of both the printer and the computer.

(2) The data transfer settings between the printer and the computer may differ. You can use the self-test printout to see the printer's interface settings. If the printer fails to print, please contact your dealer or technical support.
