Printer Says No Computer Found When Trying To Scan

[StephenM32]

I have a Office jet Pro 7740 and its connected to my home network. I have no problems printing from my Mac Pro or my iphone to the device, but when I attempt to scan from the printer to my computer, it says "no computer found". I go to the HP Utility and select Scan to Computer and Enable Scan to Computer...but it responds "Communication Error...unable to connect with device..." I've uninstalled all software and reinstalled from my computer, as well as removed and re added the printer under the system preferences printer & scanners. Running MAC OS Sonoma.

Hi @StephenM32,

Welcome to HP Support Community.

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

It sounds like you've already tried several common troubleshooting steps for your HP OfficeJet Pro 7740 when encountering issues with scanning to your Mac. Here are a few additional steps you can take to potentially resolve the issue:

Check Network Configuration:

• Ensure both your printer and Mac are connected to the same network. This can sometimes be overlooked if one device is connected to a guest network or a different frequency band (2.4 GHz vs. 5 GHz).
• Verify that the network settings on the printer are correctly configured. You can usually check this through the printer's built-in menu under 'Network Settings' or similar.

Update Software and Firmware:

• Ensure your Mac OS Sonoma is up to date. macOS updates often include driver updates that can fix compatibility issues.
• Check if there is a firmware update available for your printer. This can be done either through the printer menu or the HP website.

Enable Scanner from HP Utility:

• Even though you have already enabled scanning to computer via the HP Utility, try toggling this setting off and on again while your Mac and printer are actively connected to the network.
• Ensure that any firewall settings on your Mac are not blocking the connection to the printer.

Reset Printer’s Network Settings:

• Try resetting the network settings on your printer to factory defaults. This can resolve any network communication issues. You will have to reconnect the printer to your network after this step.

Use HP Smart App:

• If you haven’t already, try using the HP Smart app for macOS. Sometimes, using the dedicated HP application can help establish a better connection for all functionalities including scanning.
• Download the HP Smart app from the Mac App Store or the HP website.

Check IP Address Assignment:

• Make sure that your printer has a correct IP address. You can print a network configuration page from your printer settings/menu. This can help verify that the printer is on the same subnet as your Mac.

Check for Software Conflicts:

• Sometimes other software can interfere with network communication. Consider any recent changes or software installations that could be impacting the connection.

I hope this helps.

Take care and have a good day.
