Unable to clear lights on HP Envy Pro 6400 series

[adorem]

The bottom lights (which look like paper, which you press to copy something on the glass) on the control panel will not go out.  If I press the one on the left, it sends out a blank page.  I have reset to factory defaults and reconnected to wi-fi.  I have unplugged the printer and waited over a minute to try to clear it but the lights remain on.  I am having difficulty when I try to scan several pages through the document feeder.  I am having difficulty printing anything without shutting off and turning on the printer.  How can I clear this.

Hi @adorem,

Welcome to HP Support Community.

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

If your HP Envy Pro 6400 series printer is experiencing issues with persistent control panel lights and printing/scanning functionality, try the following steps to resolve the problem:

• Open all accessible panels and check for any paper jams or obstructions.
• Remove any paper jams carefully to avoid damaging the printer.

Clean the Document Feeder:

• Open the document feeder cover.
• Check for any small pieces of paper or debris that might be stuck.
• Use a soft, lint-free cloth to clean the rollers and other components inside the document feeder.

Since you have already reset to factory defaults and reconnected to Wi-Fi, ensure that the reset was successful by checking the printer's settings.
