Permanent "Validating... Please wait." status with genuine HP toner.

[MJSANVO]

HP LaserJet MFP M234dwe. Windows 11.

Replaced old ink cartridge with brand new 134/135 W8007x. Status on validating for 4 days at this point. I've cleaned contacts, cycled power, removed and reinstalled printer and software on pc, including HP Smart, and checked for a firmware update (it's current). I need to force it to validate or bypass the validation check like yesterday.

@MJSANVO, Welcome to HP Support Community. 

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

I understand you're experiencing a persistent "Validating... Please wait." message after installing a genuine HP toner cartridge in your HP LaserJet MFP M234dwe printer. You've already done a great job troubleshooting, 
cleaning contacts, reinstalling software, and checking firmware.

Here are some additional steps that may help resolve this issue:

Check HP+ Enrollment and Internet Connection

• The M234dwe is an HP+ printer, which requires:
  • An active internet connection.
  • The printer to be signed in to your HP account via the HP Smart app.
• Ensure the printer is connected to Wi-Fi and not in offline mode.
• Open the HP Smart app and verify that the printer is claimed to your HP account.

Use HP Smart’s Diagnose & Fix Tool

• Open the HP Smart app on your PC.
• Go to “Printer Settings” > “Advanced Settings”.
• Select “Diagnose & Fix” and follow the prompts.
• This tool can often resolve firmware or validation loop issues.

Reset the Printer

• Turn off the printer.
• Unplug the power cord from the wall and printer.
• Wait 60 seconds.
• Plug it back in and power on the printer.

Reinstall the Toner Cartridge

• Power off the printer.
• Remove the toner cartridge.
• Gently clean the metal contacts on the cartridge and inside the printer using a lint-free cloth.
• Reinsert the cartridge firmly and power the printer back on.

I hope this helps. 

Take care and have a good day.
