HP Envy 6458e. All in one printer.  Every single one of the error lights is blinking all at once.  I have turned it off and restarted it multiple times. They continue to blink.  I am unable to print.

Hi @Ellen136 ,

Welcome to The HP Support Community.  

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

I understand the error lights on an HP ENVY 6458e All-in-One Printer are blinking simultaneously, it usually indicates a serious issue that needs attention. Here are a few steps to try and resolve this:

Check for Paper Jams: Ensure there are no paper jams inside the printer. Open the paper tray and any other access panels to check for and clear any jammed paper.

Check Ink Cartridges: Make sure the ink cartridges are properly installed. Remove and reinstall the cartridges to ensure they are seated correctly.

Power Cycle the Printer: Unplug the printer from the power source, wait for about 60 seconds, then plug it back in and turn it on.

Reset the Printer:

• With the printer on, press and hold the "Cancel" and "Wireless" buttons simultaneously for about 15 seconds until the lights blink.
• Release the buttons and wait for the printer to restart.

Inspect for Hardware Issues: Look for any obvious signs of damage or misalignment in the printer’s hardware components.

Update Firmware: If possible, check if there are any firmware updates available for your printer model and install them. Update the firmware on an HP printer
