Clover devices have built-in diagnostic features to help you troubleshoot issues related to your network and connected printers. You may also be asked to use the diagnostic tools while working with Clover Support or Developer Relations (DevRel) to determine the cause of a device issue.

Launch diagnostics

To open the diagnostics tools, complete the following steps.

1. On the device home screen, tap the Help app.
2. Tap the menu icon > Diagnostics. The Diagnostics page appears.

3. Review the high-level information on the status bar about the device connection to the Wi-Fi and the server. The device also receives notifications from the Clover Mobile Dashboard Android or iOS apps. If notifications do not display as expected, you can verify the connection to the notification service on the status bar.

View connection status and history

While the status bar gives a basic indication of the device's Wi-Fi connection, you can view the connection history and more detailed information, such as IP addresses and connection uptime or downtime.

1. On the device home screen, tap the Help app.
2. Tap the menu icon > Diagnostics. The Diagnostics page appears.
3. Tap Connection Status. The Connection History page appears.

4. Review the Wi-Fi connection status, IP address, server, and notification status information.

Test network speed

A slow connection to the Clover server can cause some device issues. To check your network's speed:

1. On the device home screen, tap the Help app.
2. Tap the menu icon > Diagnostics. The Diagnostics page appears.
3. Tap Connection Status. The Connection History page appears.
4. Tap Speed Test. The Speed Test page appears.
5. Tap Begin Test. The device sends test requests to the server and displays the result.

View printer status and queue

If a printing job does not finish as expected, you can open the printer queue to see if there is an issue with the print job.

1. On the device home screen, tap the Help app.
2. Tap the menu icon > Diagnostics. The Diagnostics page appears.
3. Tap Print Queue. The Printer Queue page appears.

4. Troubleshoot printer issues as follows:

• To remove all pending print jobs from the queue, tap Clear Queue.
• To retry pending jobs (after adding paper or fixing a connection issue), tap Retry Print Jobs.
• To modify an existing printer configuration, tap Set Up Printers.

📘

NOTE

A pending print job is automatically removed from the queue after 60 minutes.

View network queue

All messages sent from the device to a Clover server are queued for transmission. If a network failure or other issue prevents the message from being sent as expected, it remains in the queue until the problem is resolved. To open the queue and check for pending messages:

1. On the device home screen, tap the Help app.
2. Tap the menu icon > Diagnostics. The Diagnostics page appears.
3. Tap Network Queue. The Network Queue page appears.

4. Review the network call and status.

Verify merchant information

Clover devices are provisioned for individual merchants. You can verify this merchant-to-device association.

1. On the device home screen, tap the Help app.
2. Tap the menu icon > Diagnostics. The Diagnostics page appears.
3. Scroll down on the page and tap Additional Details. The Additional Details page appears.

4. Review the merchant name, merchant ID (mId), Clover ID, and the device serial number.
