USB-A does not support communication with the host device.

USB-C and USB-B cannot be connected simultaneously for the host device.

When both devices are connected while the printer remains turned on, only communication with the first connected device is established. In addition, when the mPOP power is turned on while both devices are connected, the product preferentially communicates with the Windows or Android device connected to USB-B, and only provides power to the iOS device (iPad/iPhone/iPod touch) or Android device connected to USB-C.

To swap connection between USB-B and USB-C, remove all the USB cables and connect the host devices to the appropriate ports. Do not connect unnecessary cables.

The USB cable connection method varies depending on the operating system of your PC, smartphone, or tablet. Check whether the cable is correctly set to suit your environment.

• The connector may also be loose. Check that the USB cable or Lightning cable is correctly connected between the printer and the PC, smartphone, or tablet.
• The USB cable or Lightning cable may have been damaged. If this error recurs after the cable is connected again, connect another cable, and check the status.
• If a USB cable or Lightning cable is re-connected immediately after disconnecting it, the iOS device may fail to recognize mPOP. If this occurs, either disconnect the cable and wait for 2 seconds or longer before re-connecting, or else turn the mPOP power off and back on again.

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 may also mean that the power socket is loose. Check and make sure that the power socket is correctly connected.

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.
If using a tablet, you can perform an easy connection test for the cash drawer using the utility.

If the cash drawer moves slightly or refuses to open, it may be that something is stuck inside preventing it from opening. Pull the front face of the cash drawer forward and confirm.

If anything over the maximum withstanding load (8 kg) is placed on top, it may prevent the cash drawer from opening. The surface in the front is not designed to withstand heavy weight. If an object is placed on top, then remove the object and try again.

Using the lock release lever will enable you to open the cash drawer by hand.
Also if the drawer open function is effective with the multi-function button, you can use the multi-function button to open the drawer.

Check that there are no bills/coins/foreign objects that have dropped in the cash drawer storage area.

If anything over the maximum withstanding load (8 kg) is placed on top, it may prevent the cash drawer from closing. The surface in the front is not designed to withstand heavy weight. If an object is placed on top, then remove the object and try again.

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 may also mean that the power socket is loose. Check and make sure that the power socket is correctly connected.

If blank paper is being ejected, the paper roll may be set in the wrong direction. Check the direction of the paper roll to make sure that the paper is set correctly.

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.

If the Power LED is blinking or the Error LED is lit/blinking, refer to the "LED Display" section and check the status of the product.

Only one type of interface can be used for printing communication. Check that they are connected via the interface and ports specified in the app.

Check whether Self-Printing works correctly.
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.

Do not touch the paper or block the outlet while the paper is being discharged.

It may be that the paper width, paper thickness and such do not meet the required specifications. Check the appropriate paper roll specifications and use paper that meets the printer's specification.
