Hi @KTUK 

Welcome to HP Support Community.

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

It sounds like you're dealing with an Error Code 6 on your HP ENVY 6400 Series printer, which typically indicates a problem with the printer's cartridges, hardware, or wireless connectivity. You've already tried some common troubleshooting steps like removing and replacing the cartridge, performing a factory reset, and checking for paper jams. Let’s work through some other solutions that might resolve this issue.

Step-by-Step Troubleshooting for Error Code 6

Check and Re-seat the Ink Cartridges: Sometimes, the issue could be with the cartridge installation. Even if you've already replaced or reseated it, it's a good idea to double-check.

• Turn off the printer.
• Open the cartridge access door.
• Remove both ink cartridges from their slots.
• Inspect the cartridges for any visible damage or ink leaks.
• Clean the contacts on both the ink cartridges and the printhead using a soft cloth or lint-free cloth (dampened with water).
• Reinstall the cartridges, making sure they snap securely into place.

Perform a Hard Reset: A hard reset can sometimes clear any residual errors or glitches.

• Turn off the printer and unplug the power cable from the back of the printer.
• Wait 60 seconds.
• Plug the power cable back in, and then turn the printer back on.

Check for Firmware Updates: The error might also be related to outdated firmware. If your printer is connected to Wi-Fi, you can check for firmware updates via the HP Smart app.

• Open the HP Smart app on your phone or computer.
• Select your printer.
• Go to Printer Settings > Printer Update (or similar).
• Check for any available firmware updates and install them.

Check for Wireless Connectivity Issues: Since your printer is connected via Wi-Fi, an issue with the wireless connection could trigger error codes. You should ensure that the printer is still properly connected to your network.

• Restart your router: Sometimes, the issue could be with your Wi-Fi connection. Power cycle the router by turning it off, waiting 30 seconds, and turning it back on.
• Reconnect to Wi-Fi:
  1. On the printer, press the Wi-Fi icon to open the wireless settings.
  2. Reconnect your printer to the correct network.
  3. You can also reset the printer’s network settings by pressing and holding the Wireless button on the printer for 5-10 seconds.

Check for Paper Jams Again**: Even though you've checked for paper jams, sometimes smaller pieces of paper or debris can get stuck in hard-to-reach areas. Inspect the paper tray, output tray, and any inside areas of the printer that you might have missed.

• Carefully remove the paper tray and check for any scraps of paper.
• Use a flashlight to look for anything stuck in the paper feed rollers or printing mechanism.

Run the HP Print and Scan Doctor: HP offers a diagnostic tool called HP Print and Scan Doctor that can help automatically troubleshoot and resolve printing issues, including error codes.

• Download and install HP Print and Scan Doctor from HP’s official website.
• Open the tool and select your printer.
• Follow the on-screen instructions for diagnostics. The tool will check for common issues like connectivity problems or cartridge issues and attempt to fix them.

Perform a Factory Reset (Again): If the error persists, it may be worth trying another factory reset to clear any configuration errors that might be causing the problem.

• Turn off the printer.
• Press and hold the Power button and Wi-Fi button together for about 10-15 seconds.
• The printer should perform a reset, and this could potentially clear out the error code.

I hope this helps.

Take care and have a good day.
