If the red LED is lit, the paper cover is open.

If the red LED is blinking, either the paper has been fully used or
the print head is overheated. (Refill with paper, if needed, or turn
the printer off for at least 10 minutes.)

If the red LED continues to blink, it may indicate a more serious

1) When using Bluetooth
If the printer is ready for wireless communication with any
Bluetooth, the green lamp as well as the battery status lamp is
turned on.
2) When using wireless LAN
The right indicator shows the signal strength from wireless LAN.
The green lamp blinks for acceptable signal strength while the
red lamp blinks for weak signal strength.
In power save mode, only the Status lamp is lit.
NOTE
The power saving mode is activated after the first communication, with the default
time interval being 10 seconds.
