Hi @jackie21842,
Welcome to HP Support Community.
Thank you for posting your query, I will be glad to help you.
The error message "An internal communication error has occurred in the Scanner Subsystem. Contact support" indicates a problem within the scanner's internal communication processes. This issue typically affects the scanning functionality, but as noted, printing and faxing should still work. Here are some steps you can try to resolve this issue:
Basic Troubleshooting Steps
Power Cycle the Scanner/Printer:
- Turn off the scanner or printer.
- Unplug the power cord from the outlet.
- Wait for about 30 seconds.
- Plug the power cord back in and turn the device on.
Check Connections:
- Ensure all cables (USB, network, etc.) are securely connected.
- If using a USB connection, try a different USB port on your computer.
- If using a network connection, ensure the network cable is securely plugged in or check the Wi-Fi connection.
Restart Your Computer:
- Sometimes, restarting your computer can resolve internal communication errors.
Update Scanner/Printer Drivers:
- Visit the HP website to download and install the latest drivers for your scanner/printer.
Advanced Troubleshooting
Reinstall the Scanner/Printer Software:
- Uninstall the current scanner/printer software from your computer.
- Restart your computer.
- Download and install the latest version of the software from the HP website.
Check for Firmware Updates:
- Check the HP website for any firmware updates for your scanner/printer.
- Follow the instructions provided to update the firmware.
Scanner Hardware Reset (if applicable):
- Some scanners have a reset button or a combination of buttons you can press to reset the hardware. Refer to your scanner's manual for specific instructions.
Check for Interference:
- Ensure there are no other devices nearby that could be causing interference with the scanner's communication.
I hope this helps.
Take care and have a good day.
