stuck in validating

[watersbn]

I just changed my print cartridges in the OfficeJet Pro 8120e printer, as i had cancelled my Smart INk subscription. It is now stuck on validating. I have been all round the houses and all the troubleshooitng, and uninstalled HP Smart, reinstalled, and rebootted the router, the network, the laptop and the printer. Nothing will get this printer off validating. and I cannot print.

Hi @watersbn,

Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding your printer!

We're thrilled to have the opportunity to assist you and provide a solution.

Try these steps:

Verify Cartridge Compatibility:

• Ensure the cartridges you installed are compatible with the OfficeJet Pro 8120e. Non-compatible cartridges might cause validation issues.

Reset the Printer:

• With the printer powered on, disconnect the power cord from the back of the printer and the wall outlet.
• Wait for at least 60 seconds.
• Plug the power cord back into the outlet and the printer.
• Turn on the printer and check if the issue persists.

Check Cartridge Installation:

• Open the ink cartridge access door.
• Ensure each cartridge is seated properly and clicks into place.

Inspect Cartridge Contacts:

• Remove each cartridge and inspect the copper-colored contacts for any debris or residue.
• Clean the contacts with a lint-free cloth.

Update Printer Firmware:

• Connect the printer to a computer or mobile device.
• Visit HP Support to download and install any available firmware updates for your printer model.

Verify Internet Connection:

• The printer might be attempting to validate cartridges online. Ensure that the printer is connected to the internet.

Perform a Factory Reset (if necessary):

• This step will reset the printer to default settings. Access the printer’s menu and navigate to 'Settings', then 'Reset'.
• Follow the on-screen instructions to complete the reset. Note that this will require reconfiguring the printer network settings after a reset.

I hope this helps.
