Title:

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 a red light indicates an error has occurred.

Indicator light color	Indicator light status	Printer status
Blue	Constantly lit	Waiting to receive data using Bluetooth or USB
	Flashing	Communicating (receiving print data)
	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 IrDA or USB
Green	Flashing	Communicating (receiving print data)
Red	Constantly lit	A system error has occurred.
Red	Flashing	An error has occurred.

Note

When the status indicator light is blue, it is possible to receive data using both the Bluetooth and USB interfaces. However, once a connection is established using one of the interfaces, data cannot be received using the other interface until printing is complete.

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 direction. There is no more paper.	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

If a system error has occurred:
The printer may be damaged. Contact the sales outlet where it was purchased.

Charging indicator light:

With the charging indicator light, the status of the power supply can be checked.
The charging indicator light has two functions.
