If the LED display indicates “link down (physically cut)”, check and make sure that the LAN cable is properly connected.

• It also may mean that the connector is loose. Confirm that both the LAN connector for the printer, network devices (router/hub and such) are securely connected.
• The LAN cable may also be disconnected. If the LED display does not change even if it is reconnected, confirm by connecting a different LAN cable.
• Check and make sure that the network device to be connected is properly working.

Also, if the LED display indicates “link down (IP address not acquired)”, please make sure that the DHCP server is usable.

If the printer body network setting was changed using Web Configuration or Telnet and cannot be connected, it may be possible for the network to be connected when the network setting is initialized.
Initialize network settings and check connections.

If connection using the set LAN setting cannot be performed, the printer will detect "link down (physically disconnected/IP address not obtained)" and print a warning message according to the setting.
Check and make sure that the network device (DHCP server, etc.) to be connected is properly working.

The warning message can be set so it will not print.

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.

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 Ready 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 has occurred or the paper is being rolled onto the rubber roller. If a paper jam has occurred, refer to the "Paper Jam" section and remove the paper in question.

Check that self-printing is 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. Check the connection setting of the host device to confirm that network connections are properly working.

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

It may be that the 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.

If the printer cover does not close, confirm that the diameter of the paper roll is 83 mm or smaller. Check the appropriate paper roll specifications and use paper that meets the printer's specification.

If the printer cover does not open even when you press the open lever, it is likely that a paper jam has occurred, and locked the cutter. Refer to "Cutter Lock" to release the lock.

Confirm that the Ready LED of the main unit is turned on.
Charging USB peripherals such as a tablet can only be done while the power of the main unit is turned on.

Confirm that the USB cable for the tablet is connected to the USB port (1.0A) of the main unit.

The USB port on the back of the printer only supports power supply.

Use TSP100III Utility to easily check TSP100III settings. You can also check settings using the self-printing function.

This machine provides the de-curl function to correct curls generated in thermal paper roll. The de-curl mechanism is always running during paper feeding.

• However, this function cannot remove curls completely.
• A receipt may be slightly folded near the top depending on the time in which receipt paper is left during the period from when a receipt is printed until the next one.
• The de-curl effect varies depending on the paper you use or your environment.
• Depending on the type or remaining amount of thermal paper roll, a receipt may be warped in a direction opposite to the normal direction by the de-curl function.
