E6 Error Amber Flashing Warning LEDS HP Envy 6420e

[FionaAust81]

I have reset the printer many times, left it unplugged overnight and have checked for any jams etc and there are none. I can't get this error to go away and I require the printer for Uni.

Can anyone help at all on how to get this out of the error state. Driving me nuts over here.

Hi @FionaAust81,

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 E6 error on the HP ENVY 6420e indicates a carriage jam or a similar issue. Since you've already tried resetting and unplugging the printer, as well as checking for jams, here are a few additional steps you can try:

Check the Carriage Path:

• Turn off the printer and open the front cover.
• Gently move the carriage (the part that holds the ink cartridges) left and right to check if it's stuck.
• Make sure there are no obstructions or small bits of paper blocking the carriage path.

Clean the Encoder Strip:

• The encoder strip is a clear strip running across the printer behind the carriage.
• Carefully clean it with a soft, lint-free cloth slightly dampened with water. Be gentle to avoid damaging the strip.

Inspect the Rollers:

• Check the paper rollers for any stuck paper bits or debris.
• Clean the rollers with a lint-free cloth slightly dampened with water.

Update Firmware:- Update the firmware on an HP printer

• Ensure your printer’s firmware is up to date. You can do this by visiting the HP support website and downloading the latest firmware update for your model.

Reset the Printer:

• Disconnect the power cord from the back of the printer while it’s on.
• Wait for at least 60 seconds.
• Reconnect the power cord and turn on the printer.

Reinstall the Ink Cartridges:

• Turn on the printer and open the ink cartridge access door.
• Remove and reinstall the ink cartridges to ensure they are properly seated.

Check for Software Issues:
