[KevTr]

Printer was functioning properly. Since I installed the HP+ app it now got stuck in a validating process (on screen). Not possible to execute any commands. When shutting down the printer (unplugging it from power for 60mins) and restarting it first shows the menu indicating there is no network available. However the WIFI network blue light is burning continuous so ok. Then is starts in it(s validating ... please wait screen and nothing can be done. Who has advise to help me out?

Hi @KevTr,

Welcome to HP Support Community.

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

It sounds like your HP OfficeJet 9120e is stuck in a validation loop after installing the HP+ app. Here are some steps you can try to resolve the issue.

Perform a Full Factory Reset:

• Unplug the printer from the power source while it’s on.
• Wait 60 seconds.
• Press and hold the printer's Power button while you plug it back in, continuing to hold the power button for 15-30 seconds.
• If the printer does not automatically power on, turn it on manually.
• The reset process should trigger, resetting the device to factory settings.

Check for Firmware Updates:

• If the printer responds after the reset, check for any firmware updates.
• You can do this from the printer’s control panel or via the HP Smart app if it re-establishes connection with your network.

Remove HP+ App/Reset Network Settings:

• Since the issue started after installing the HP+ app, uninstall the HP+ app from your devices (phone, PC).
• Reset the printer's network settings to ensure it isn’t caught in a miscommunication loop:
  • Go to Settings → Network Settings → Restore Network Defaults.
• After resetting, reconnect the printer to your WiFi network using the setup menu.

HP Support Diagnostic Tool:

• If the above steps do not help, try using the HP Print and Scan Doctor tool on your computer to identify and troubleshoot the issue further. You can download it from HP’s support page.

I hope this helps.

Take care and have a good day.
