What do the indicator lights on the printer mean?

Description:

There are two indicator lights on the printer: the Status light and the Charging light. Each indicator light shows the status of the printer as described below.

Status indicator light:

A blue or green light indicates the printer is operating correctly, while red indicates an error has occurred.

Indicator light color	Indicator light status	Printer status
Blue	Constantly lit	Waiting to receive data using Bluetooth or the USB
	Flashing	Receiving data using Bluetooth
	Flashing in long intervals	Sleep mode (power-saving standby condition, possible only when receiving data using Bluetooth)
Green	Constantly lit	Waiting to receive data using USB
Green	Flashing	Receiving data using USB
Red	Flashing	An error has occurred.
Red	Constantly lit	A system error has occurred.

If an error has occurred, check for the following causes.

Error description	Remedy
There is no paper cassette installed. The paper cassette is installed facing the wrong directions. There is no more paper in the cassette.	Correctly install a paper cassette containing paper.
A paper misfeed occurred.	Remove the misfed paper.
A transmission error occurred.	Check the transmission status.
An overheat error occurred.	The inside of the printer has started to overheat. Wait until it cools down.

Note

2. checking the battery level (while running off the built-in lithium ion battery)

Indicator light status	Battery level
Off	More than 60% charged
Flashes once	Less than 60% charged
Flashes twice	Less than 30% charged
Flashes 3 times continuously	Almost empty

Note

When the indicator light starts flashing 3 times continuously, charge the battery. Frequently recharging the battery will diminish its storage capacity. We recommend always waiting until the machine indicates that battery needs recharging before doing so. Refer to the FAQ: How to prolong the life of your rechargeable battery
