@MoGunn1, Hi there, and welcome to HP Support Community!

Thank you for reaching out with your concern. I'm glad to assist you today.

If your HP Envy Photo 7833 All-in-One Printer is printing fine but the scanner and fax functions aren't working, here are some steps to help you troubleshoot and resolve the issue.

Use HP Smart App's Diagnose & Fix Tool

HP Smart includes a built-in tool that can automatically detect and fix issues with scanning and faxing.

1. Download or open the HP Smart app: HP Smart
2. Open the app and select your printer.
3. Click the wrench icon (Windows) or printer dropdown (Mac).
4. Select Diagnose & Fix and follow the on-screen instructions.

Troubleshoot Scanner Issues

If scanning fails or the computer can't detect the scanner:

• Ensure the printer is connected via USB or Wi-Fi.
• Restart both the printer and your computer.
• Try scanning using the HP Smart app or Windows Fax and Scan.
• If using Windows, check for scanner errors:

Troubleshoot Fax Issues

If faxing doesn’t work:

Run a Fax Test:

• On the printer control panel, go to Fax > Setup > Run Fax Test.
• Review the report and follow any instructions.

Check Connections:

• Ensure the phone line is connected to the 1-LINE port.
• If using an answering machine, connect it to the 2-EXT port.

Adjust Fax Settings:

• Lower fax speed to “Slow” or “Standard”.
• Enable Error Correction Mode.
• Set Auto Answer to ON.
• Use black & white mode for compatibility.

Reset the Printer

Sometimes a simple reset can fix internal errors:

1. Turn off the printer.
2. Unplug the power cord from both the printer and wall.
3. Wait 60 seconds.
4. Plug it back in and power on.
