What to do if red LED flashes and beeper alarms on Sunso Printer?
- AAmy ArnoldAug 6, 2025
If the red LED on your Sunso Printer is flashing and the beeper is alarming, it could be due to several reasons. First, the paper might have run out, so try loading a new roll of paper. Another possibility is that the thermal print head is overheated; in this case, turn off the printer and allow it to cool down before resuming. Also, ensure that you are printing with the specified voltage. If the cutter is jammed, open the printer cover to allow the cutter to return to its home position. Finally, make sure that the printer cover is completely closed.
