While the printer is connected to a Mobile Device via Bluetooth, the connection will be lost if the printer is turned off or distance between them increases. When the connection is retried, the printer and Mobile Device are in their normal states but the connection is not re-established.
Time-out periods are built into PDA or printer for holding the existing connection. If the connection is lost for unknown reasons, try the connection again after 30 seconds.
In case that previous printer keeps having bluetooth connection, turn on the printer cover to release the previous connection to make it new connection.
