Hi @Shrein26,

Welcome to HP Support Community.

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

If your HP ENVY 7640 e-All-in-One Printer reports a paper jam but no paper is visible, it could be caused by a sensor issue or a small piece of debris lodged in the mechanism. Here's how to resolve the issue.

Power Cycle the Printer:

• Turn off the printer and unplug it from the power source.
• Wait for at least 2-3 minutes to allow the internal components to reset.
• Plug the printer back in and turn it on.

Inspect Paper Path Thoroughly:

• Open all accessible areas, including:
  • Input and output trays.
  • Rear access panel (or duplexer, if applicable).
  • Under the scanner lid and around the carriage area.
• Use a flashlight to check for any small scraps of paper, debris, or foreign objects.

Clean the Paper Rollers:

• Dampen a lint-free cloth with distilled water or isopropyl alcohol.
• Gently clean the rollers in the input and output tray areas.
• Rotate the rollers manually to ensure thorough cleaning.

Check the Carriage Path:

• Open the printer cover and ensure the carriage (the part holding the ink cartridges) moves freely.
• If the carriage is stuck, gently push it to the center and check for obstructions.

Reset the Printer:

• After cleaning, perform a reset by:
  • Turning off the printer.
  • Holding the power button for 30 seconds.
  • Turning it back on.

Inspect the Sensors:

• A faulty or dirty paper sensor may falsely indicate a jam. Use compressed air to clean the interior, focusing on areas near the rollers and paper path.

Perform a Printer Test:

• Print a test page to see if the error persists.

I hope this helps.

Take care and have a good day.

Have tried all the listed resets.  NO change in status.  Throwing away another HP printer because of crappy software and support.  Will not buy another HP product again.
