Epson printer / TSE not accessible


Depending on your infrastructure, it can occasionally happen that the Epson printer or the technical security device cannot be reached without problems. We had to experience this problem especially with the routers of the Telekom. The printer often received a new IP address so that TYRIOS could no longer access the TSE.


The following procedure has provided relief for the problem:

  1. Enter the IP address of the printer in the browser. You will be asked to enter a user name and password. If you have not changed this, it is "epson" and the password is the serial number of the printer.
  2. You will be taken to the administration of your Epson printer.
  3. Click on TCP/IP in the "Configuration" section
  4. Change the setting "Acquiring the IP Address" to "Manual". This means that the IP address is no longer assigned automatically, but you can enter it manually.
  5. Store the IP address that you had when you set up the TSE and the printer. Leave the other settings as they were.
  6. Click on "Send". The printer will then restart.

Tips und Tricks:

If the IP address has changed, your router has reassigned the IP address. This means that your SSL certificate is no longer accepted and you receive a security warning in the browser. With the procedure described above, you can change the IP address back to the original IP address and the SSL certificate will then work again.

However, it is possible that the original IP address is no longer available because it is now being used by another device. In this case, remove this device from your network or adjust the TSE and terminal settings to the changed IP address.
