Hi @fbaltman ,

Welcome to The HP Support Community.  

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

I understand you're encountering an issue with your scanner. Let's troubleshoot it step by step:

• Check Connection: Ensure that the scanner is properly connected to your computer. Check the cables and connectors to make sure everything is plugged in securely.
• Power Status: Verify that the scanner is powered on. Check if there are any indicator lights on the scanner to confirm that it's receiving power.
• Restart: Sometimes, a simple restart can fix communication issues. Try restarting both the scanner and your computer.
• Driver Issues: Check if the scanner drivers are installed correctly on your computer. If not, reinstall the drivers from the HP website. Software and Drivers for HP OfficeJet 5746 e-All-in-One Printer
• Software Compatibility: Make sure that the scanning software you're using is compatible with your scanner model and the operating system of your computer.
• Test with Different Software: Try scanning using different software to see if the issue persists. This can help determine if the problem lies with the scanning software or the scanner itself.
• Update Software/Firmware: Check if there are any updates available for your scanning software or firmware for the scanner. Updating to the latest version may resolve the issue. Update the firmware on an HP printer
• Check for Hardware Issues: If none of the above steps work, there might be a hardware problem with the scanner itself.
