[Atropa]

Lighting on my printer, control panel (touch panel) is blocked on error B3273538.
No way to light off the printer, except by disconnect it from AC cable.
No way to reset the printer.
Have you any idea of the meaning of this error?
Have you any idea about to solve it?

Thank you in advance.

Hi @Atropa,

Welcome to HP Support Community.

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

The error code B3273538 on an HP Photosmart 7520 usually indicates a problem with the printer's firmware or hardware, potentially related to the control panel or other internal components.

Here are some steps you can take to troubleshoot and potentially resolve the issue.

Perform a Hard Reset:

• Unplug the printer from the AC power source.
• Wait for about 60 seconds.
• Plug the printer back in and turn it on to see if the error persists.

Check for Hardware Issues:

• Inspect the printer for any visible damage or loose connections, especially around the control panel and internal components.
• If you feel comfortable doing so, you can open the printer (following any safety guidelines) and check for any disconnected or misaligned cables.

Update or Reinstall Firmware:

• Sometimes a firmware update can resolve persistent errors. If the printer's control panel is unresponsive, you might need to use HP's support website to download the latest firmware and instructions for installation.

I hope this helps.

Take care and have a good day.
