1. Is the power turned on? or Is the power cable connected properly?
Please check that the Power LED is turned on.
If the Power LED does not turn on even when the power is turned on, it may mean that the power cable is not properly connected. Please check. It also may mean that the electrical outlet is loose. Check and make sure that the power outlet is properly connected.
2.Is the sheet facing the right direction?
If a white sheet is being ejected, then it may be possible that the paper roll is set in the opposite direction. Check the direction of the paper roll to make sure that the paper is set correctly.
3.Does the paper being used fit the specifications for the printer?
As this product is equipped with a thermal printer, it will not print on ordinary paper. Also, if there are issues such as the printed words being faint, it may be that the paper does not meet the specifications, or the paper has become old and deteriorated. Check the appropriate paper roll specifications and use paper that meets the printer's specification.
4.Is the LED display in standby status (Power LED lit/Error LED turned off)?
If the Power LED is blinking or the Error LED is lit/blinking, refer to the LED lamp display and check the status of the product.
If you can hear the printer operating but the paper is not being ejected, there is a possibility that a paper jam is occurring or the paper is being rolled onto the rubber roller. If a paper jam is occurring, refer to the "Paper Jam" section and remove the paper in question.
6.Is self-printing working properly?
If self-printing can print properly, then it may be that communication with a host device such as a tablet and PC, is not established. When using a Bluetooth connection, check the connection setting of the host device if the paring is properly completed. If connected via USB, then check that the USB cable is properly connected.
