Hi @BoiseSteve ,

Welcome to The HP Support Community.  

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

I understand you are getting an E3 error on the HP ENVY Pro 6455 All-in-One Printer indicates a carriage jam or an issue with the ink cartridge carriage. Here's how to troubleshoot and resolve the problem:

Steps to Fix the E3 Error:

Power Cycle the Printer:

• Turn off the printer.
• Unplug it from the power source.
• Wait for about 2-3 minutes, then plug it back in and power it on.

Check for Obstructions in the Printer:

• Open the printer's access door to expose the ink cartridge area.
• Look for and remove any jammed paper, torn pieces, or foreign objects inside.
• Ensure the carriage (the part holding the ink cartridges) moves freely from side to side.

Inspect the Ink Cartridges:

• Open the cartridge access door.
• Remove the ink cartridges carefully.
• Check for tape, debris, or anything blocking the cartridges or carriage.
• Clean the electrical contacts on the cartridges and inside the printer using a lint-free cloth slightly dampened with distilled water.

Reinstall the Ink Cartridges:

• Reinsert the cartridges securely.
• Ensure they "click" into place.

Reset the Printer:

• After reinstalling the cartridges, close the access door and check if the error persists.
• Reset the printer by unplugging it while it is on, waiting 60 seconds, then plugging it back in.

Perform a Test Print:

• If the error clears, try printing a test page to confirm functionality.

If the Issue Persists:

Firmware Update:

• Check for and install any firmware updates via the HP Smart App.
• Ensure the printer is connected to your computer or mobile device.
