Hi everyone!
I came across error that has not been described in any support page. I'm getting all lights blinking and E showing, but without an error code. 
Any ideas?

Hi @samrex004 ,

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 error you're describing on the HP Ink Tank Wireless 415 printer (all lights blinking with "E" on the display but no specific error code) is a generic indication of a hardware issue or a problem with the printer's components. Here are some troubleshooting steps you can try:

1. Power Cycle the Printer

• Turn off the printer and unplug it from the power source.
• Wait for about 2-3 minutes.
• Plug the printer back in and turn it on to see if the error clears.

2. Check for Paper Jams

• Open all accessible panels and inspect for any paper stuck inside.
• Even a small piece of torn paper can cause such errors.
• Use a flashlight if needed to check thoroughly.

3. Inspect Ink Tanks

• Ensure all ink tanks are properly filled and seated correctly.
• If any tank is completely empty, refill it and reset the ink levels in the HP Smart app.

4. Check Printhead Alignment

• Open the printer and check if the printhead is stuck or improperly seated.
• Carefully move the printhead carriage to the center and ensure it's not obstructed.

5. Reset the Printer

• Press and hold the Power button and the Cancel button for 3-5 seconds.
• Release the buttons and wait for the printer to restart.

6. Inspect the Power Source

• Ensure the printer is connected directly to a wall outlet, not through a power strip or surge protector, which can sometimes cause power fluctuations.

7. Firmware Update Update the firmware on an HP printer

• If you can connect the printer to your computer, check for firmware updates using the HP Smart app or the HP Support Assistant.

8. Perform a Hard Reset

• While the printer is on, disconnect the power cord from the back of the printer and the wall.
• Press and hold the power button for 15 seconds.
• Reconnect the power cord and turn the printer back on.

9. Check for Hardware Issues

• If the above steps don’t resolve the issue, there might be a hardware fault, such as a defective printhead or sensor. Contact HP Support for further diagnostics.
