Hi @Marty19501968,

Welcome to The HP Support Community.  

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

I understand your HP ENVY 6400e printer is stuck on validating print cartridges despite trying different sets of cartridges and cleaning the pins, there are a few more troubleshooting steps you can follow:

1. Check for Firmware Updates

Ensure your printer has the latest firmware. Firmware updates can resolve various issues, including problems with cartridge validation.

• Download and Install Firmware:
  1. Visit the HP Customer Support - Software and Driver Downloads.
  2. Enter your printer model (HP ENVY 6400e).
  3. Download and install any available firmware updates.

2. Reset the Printer

A full reset might help clear any internal errors.

1. Perform a Full Reset:
   • Disconnect the power cord from the back of the printer while it is still on.
   • Unplug the power cord from the wall outlet.
   • Wait for 60 seconds.
   • Plug the power cord back into the wall outlet and then reconnect it to the back of the printer.
   • Turn on the printer if it does not turn on automatically.

3. Check Cartridge Compatibility

Ensure that the cartridges you are using are fully compatible with your printer model.

• Compatible Cartridges:
  • HP 67 Black Original Ink Cartridge
  • HP 67 Tri-color Original Ink Cartridge
  • HP 67XL High Yield Black Original Ink Cartridge
  • HP 67XL High Yield Tri-color Original Ink Cartridge

4. Inspect the Cartridge and Printer Contacts

Even if you've cleaned the contacts, ensure there is no damage.

1. Inspect Contacts:
   • Look for any visible damage or debris on the cartridge contacts and the printer’s cartridge holder.
   • Use a lint-free cloth and distilled water to gently clean the contacts again.

5. Use the HP Print and Scan Doctor

HP provides a tool called HP Print and Scan Doctor that can diagnose and resolve many printing and scanning problems.

• Download and Run the Tool:
  1. Visit the HP Print and Scan Doctor page.
  2. Download and run the tool.
  3. Follow the on-screen instructions to diagnose and fix issues.

6. Reinstall Printer Drivers

Sometimes, reinstalling the printer drivers can resolve validation issues.

1. Uninstall and Reinstall Drivers:
   • Go to Control Panel > Devices and Printers.
   • Right-click on your HP printer and select Remove device.
   • Download the latest drivers from the HP website and install them.
