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.
