Hi @JbsApTaku,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

If you're encountering the "Invalid Credentials" error while setting up the scanner on your HP OfficeJet Pro 9730 Wide Format All-in-One Printer, here are the accurate troubleshooting steps specific to Windows:

Step 1: Verify Windows Folder Sharing Permissions

1. Right-click on the shared folder (folder1) and select Properties.
2. Go to the Sharing tab > Advanced Sharing > Permissions.
3. Ensure user1 has Full Control (Read/Write/Modify).
4. In the Security tab, also ensure user1 has Full Control.

Step 2: Ensure Proper Network Path

1. Open Command Prompt on your computer.
2. Type hostname and press Enter to confirm the correct Computer Name.
3. In the printer's web console, ensure the Network Path is correctly entered in the format: \\COMPUTERNAME\folder1
4. Verify the username is entered as:  COMPUTERNAME\user1

Step 3: Validate Credentials

1. Ensure user1 has a password. Windows does not allow network sharing with blank passwords.
2. Log out of user1 and log back in to confirm the password is correct.
3. Test connecting to the shared folder from another device using the same credentials.

Step 4: Disable Password Protected Sharing (Optional)

1. Go to Control Panel > Network and Sharing Center.
2. Click Change advanced sharing settings.
3. Under All Networks, find Password Protected Sharing.
4. Toggle it to Turn off password-protected sharing and save changes.

Step 5: Restart the Printer and Reconfigure the Contact

1. Reboot both your PC and Printer.
2. Remove the old contact from the printer's web console.
3. Add a New Contact with the correct network path, username, and password.
   

I hope this helps.

Take care and have a good day.
