Hi @Krystobel-55,

Welcome to The HP Support Community.  

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

I understand you are getting the clicking sound and lights being on could indicate a mechanical issue or a problem with the internal components of your HP ENVY 6420e All-In-One Printer. 

Here are some steps you can take to troubleshoot and possibly resolve the issue:

1. Check for Paper Jams

• Turn off the printer and unplug it from the power source.
• Open the printer cover and check for any paper jams or obstructions.
• Remove any debris or stuck paper carefully.

2. Reset the Printer

• Turn off the printer and unplug it from the power source.
• Wait for about 60 seconds.
• Plug the printer back in and turn it on.

3. Check the Ink Cartridges

• Open the printer cover and ensure that the ink cartridges are properly installed.
• Remove and reinsert the ink cartridges to ensure they are seated correctly.

4. Firmware Update Update the firmware on an HP printer

• Check for any available firmware updates for your printer. Sometimes, updating the firmware can resolve such issues.
• You can do this through the HP Smart app or the HP Support website.

5. Hard Reset

• Turn off the printer and unplug it from the power source.
• Press and hold the power button on the printer for about 30 seconds.
• Plug the printer back in and turn it on.

6. Check Printer Settings

• Make sure the printer settings are correct, and that there are no pending print jobs that might be causing the printer to attempt to print.

7. Inspect the Printer Mechanism

• If you're comfortable doing so, inspect the internal mechanism for any loose or broken parts.
