Hi @CNBRR7Q1T0,
Welcome to HP Support Community.
Thank you for posting your query, I will be glad to help you.
If you're getting the "scanner in use" error message frequently on your HP Color LaserJet Pro MFP 4302dw, here are some steps to troubleshoot and resolve the issue.
Restart Devices:
- Turn off your printer and unplug it from the power source for a few minutes. Plug it back in and turn it on.
- Restart your computer or any other device you're using to access the scanner.
Check for Software Conflicts:
- Ensure that no other applications or devices are trying to use the scanner simultaneously. Close any other scanning or imaging software on your computer.
Update Printer Firmware:
- Check for any available firmware updates for your printer. You can find updates on the HP website under the support section for your printer model.
Update Printer Drivers:
- Download and install the latest drivers for your printer from the HP website. Outdated drivers can sometimes cause scanning issues.
Reset Printer Settings:
- Go to the printer's settings menu and look for an option to reset the printer to factory settings. This can sometimes resolve persistent errors.
Check Scanner Settings:
- Ensure that the scanner settings on your computer are correctly configured. Sometimes, the scanner may be set to use a different source or application.
Reinstall HP Software:
- Uninstall the HP printer software from your computer and then reinstall it. This can help fix any issues with the software that might be causing the error.
Check for Network Issues:
- If you're using the scanner over a network, ensure that the network connection is stable and that there are no connectivity issues between your devices and the printer.
Clear Printer Memory:
- Sometimes, clearing the printer's memory can help. This can typically be done through the printer's control panel or settings menu.
I hope this helps.
Take care and have a good day.
