There are two LED indicators at the front of the printer, which indicate the printer state by blinking and colors.
1. Paper Color
The color of the right LED indicates the paper color. If label paper is inserted, it is indicated in white, and sticky note paper is indicated in its color.
2. Printing Ready State
When the power is supplied and the paper is appropriately recognized, both front LEDs are turned on without blinking.
3. Bluetooth Communication State
The left LED indicates the Bluetooth communication state. If printing from your mobile device, the left LED blinks while sending data, and it stops blinking after printed. If printing from your PC, the left LED is always on without blinking since Bluetooth is not used.
4. Paper Jam
If the right LED blinks and it beeps, the printer is in the state unable to print. The beep pattern indicates the error cause. If the right LED blinks and the beep repeats, it indicates that the paper is jammed. In this case, open the cover, remove the jammed paper, and insert the cartridge again.
5. No Paper/Cartridge Installation Error
If the right LED blinks and the beep repeats, it indicates the paperless state. This error occurs when paper is run out or when you close the cover without pulling the paper out of the paper outlet a little. Replace the paper cartridge with a new one, or install the cartridge appropriately by pulling the paper out of the paper outlet a little.
6. Cover Open
If it beeps once and the right LED blinks, it indicates that the cover is left open. Close the cover fully until you hear the clicking sound.
7. Printer Head Overheat Prevention
When you print tens of sheets continuously, the printer head temperature may increase. In this case, the Nemonic Label printer automatically suspends printing to prevent overheating. At this moment, the right LED keeps blinking. If the temperature returns normal and the printer resumes printing, the right LED stops blinking.
