HP Smart Tank 7602 cannot connect to Web Services to check for firmware updates

[KerryMWG]

I have an HP Smart Tank 7602 All-in-one printer. It will not check for firmware updates. Instead it always gives an error of "The printer could not connect to Web Services. Web Services might be busy or temporarily unavailable. Try again later." I have tried from the printer control panel, the EWS, the HP app and none of them work. It shows the following for the currently installed firmware: 

Firmware Version	SAYAPPPP1N003.2551B.00
Built Date	2025-12-18

Does anyone know what is going wrong?
P.S. We only have Chromebooks, no Macs, no Windows PCs.

Hello @KerryMWG, Welcome to the HP Support Community. 

Thanks for reaching out about your query regarding the HP Smart Tank 7602.

We appreciate the opportunity to assist you and are glad we could help work toward a resolution. We hope our support has been valuable.

As you're facing an issue with the web services, the first and most important step would be to ensure that your printer is connected to a stable network and has internet access. If yes, then please proceed with the below steps:

Turn on Web Services from the printer EWS

Use the HP app or an internet browser to open the printer Embedded Web Server (EWS) and then turn on Web Services.

Open the HP printer Embedded Web Server (EWS) using the printer IP address.

From the EWS home page, click the Web Services tab.

If you are prompted to log in or enter the printer PIN, enter admin for the username (HP LaserJet's only), enter the PIN from the printer label, and then click Submit or OK. This label is typically located inside the cartridge access area or printer door.

For most printers released before 2020, an information page prints with the HP ePrint email address and Printer Claim Code.

Clicking Continue on the Web Services tab (most HP printers)

If enabling Web Services fails, go to Can't connect an HP printer to Web Services.

From the Web Services Setup page, click Continue or Enable, and then follow the instructions to turn it on.

If the information page does not print, click Print Info Page or Print Information Sheet under Settings. If the issue persists, continue to the next step for alternative methods to get the code.

Take care and have an amazing day!

Use a manual DNS server for your printer connection

Use the HP app or an internet browser to open the printer Embedded Web Server (EWS) and add a manual DNS address to improve the response time from the DNS server.

Open the HP printer Embedded Web Server (EWS) using the printer IP address.

From the EWS home page, click the Network or Networking tab.

If you are prompted to log in or enter the printer PIN, enter admin for the username (HP LaserJets only), enter the PIN from the printer label, and then click Submit or OK. This label is typically located inside the cartridge access area or printer door.

• For most HP printers, select the IPv4 option under Wireless (802.11) for Wi-Fi connections or Wired (802.3) for Ethernet connections.
  
  
• For HP LaserJet printers, click Network Identification under Configuration.
  
  

Open the DNS Server settings for your connection type.

• For most HP printers, select Manual DNS Server under DNS Address Configuration, enter 1.1.1.1 for Manual Preferred DNS Server, and then 1.0.0.1 for Manual Alternate DNS Server.
  
• For HP LaserJet printers, enter 1.1.1.1 for the Primary (IPv4), and then 1.0.0.1 for the Secondary (IPv4) in the DNS section.
  

Enter the primary and secondary manual DNS addresses.

1. Click Apply to save the changes, and then restart the printer to reset the internet connection.
2. After the printer restarts, return to the EWS home page. You might need to wait a few minutes for the printer to reconnect to your network before the EWS can open.
3. Click the Web Services tab, click Continue or Enable, and the follow the instructions to turn Web Services on.
   • If turning on Web Services is successful, you are done troubleshooting.
   • If turning on Web Services fails, continue with these steps.

5. Restart the printer again and then turn on Web Services from the EWS.
