# Troubleshooting Worldline Payment Terminal

Here is a guide on what you can try to do to fix your payment terminal before contacting our support

## **My terminal/POS says "Client application shut down"**

This is most likely because Printdesk is not running on the host computer, which connects the terminal to our system.

**Check that it is running on your POS device:**

On Windows, there should be a small green Customers 1st icon visible near the clock (you might need to click the arrow to see it). If it’s not there, you need to restart the program. You may have a shortcut on your desktop, otherwise search for "Printdesk" in the Start menu and open it from there.

_Alternatively, restart your PC – it should launch automatically again._  

On Mac, the icon should be visible in the top right corner. If it’s not, try restarting it by searching for "Printdesk" in Finder.

_Alternatively, restart your Mac – it should launch automatically again._

## **If the terminal shows "Connecting..." for more than 1 minute**

In most cases where the terminal is not connected or fails to connect to the system, it is due to a change in the terminal’s IP address.

It is important that the IP address assigned to the terminal matches the one registered in our system in order for the terminal to connect and function properly.

## **Step 1 – Find the terminal’s IP address**

There are different methods for finding the IP address depending on whether you have an IPP350 or a Lane3000 terminal.  

**LANE-3000:**

-   Take your LANE-3000 terminal.
    
-   Press the red cancel button.
    
-   Enter the code **2020** and press the green button.
    
-   Read the IP address and check that it matches the one registered in our system under the integrated terminal.  
      
    

**IPP-350:**

-   Take your IPP-350 terminal.
    
-   Press the **Menu** button (just above the red cancel button).
    
-   Enter the password **2020** and press the green **Confirm** button.
    
-   Select **Help** (navigate using the arrow keys and select with the Confirm button).
    
-   Scroll down to **item 11**, where the IP address will be displayed.

## **Step 2 – Check the IP address and update it**

-   Go to **Settings** and select the **POS** tab.
    
-   Scroll down to the section called **Integrated Worldline terminal**.
    
-   Click the line with the terminal’s name to expand the settings.
    
-   Under the **IP address** field, make sure that the IP address you just retrieved from the terminal matches the one shown here – if not, you’ll need to update it with the one from the terminal.
    
-   Then click the green **Save** button and wait about 1 minute.

If the IP address is correct and Printdesk is running on the host computer, the terminal should connect within 1 minute.  

If this is not the case, please contact our support, as there may be other issues preventing the terminal from connecting that are difficult to troubleshoot as a customer.

## **Known Terminal Errors**

#### **My terminal/POS says "Declined – Online Only"**

This error typically occurs when the terminal has no internet connection.

Please check the following:

-   That the terminal has an internet connection by performing an end-of-day report on the terminal.
    
-   There should be **three green squares/dots in a circle** at the top left of the terminal screen — if they are **gray**, this indicates that the terminal is not connected to the internet.
    
-   Try restarting the terminal and reconnecting the main cable located at the back of the terminal.
    

#### **My terminal/POS says "Declined – Technical Error"**

-   Check whether the issue is with the card by testing with at least two different types of cards.
    
-   Make sure the amount being charged is over **1 DKK**.
    
-   Verify that the terminal is connected to the internet.
    
-   Try performing an end-of-day report on the terminal.
    

If none of the above resolves the issue, please contact our support.

#### **My terminal/POS says "Declined – Terminal Blocked"**

If this error appears, try performing an end-of-day report.
