Hi @Prof77,

Welcome to HP Support Community.

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

The error code OXC4EB827F HWLMICC12 C on your HP Envy 4500 printer usually indicates a hardware issue related to the printhead or ink cartridges. The printer also showing as "offline" adds another layer of complexity. Here’s how you can address these issues:

1. Troubleshoot the Error Code

Check and Reinstall Ink Cartridges

• Turn off the printer and unplug it from the power source. Wait about 60 seconds.
• Open the printer’s access door to reveal the ink cartridges.
• Remove the ink cartridges and then reinsert them firmly into their slots. Ensure they click into place securely.
• Gently clean the contacts on the cartridges and in the printer using a soft, lint-free cloth slightly moistened with distilled water. Let everything dry completely before reinstalling the cartridges.
• Plug the printer back in and turn it on.

Check the Printhead

• Remove the printhead if possible (refer to the printer's manual for instructions).
• Check the printhead for any visible damage or clogging. Clean the printhead contacts gently with a dry, soft cloth.
• Reinstall the printhead and test if the error is resolved.

2. Resolve the Offline Issue

• Ensure that the printer is properly connected to your computer via USB or is connected to your Wi-Fi network if it is a wireless printer.
• Restart both your printer and computer. Also, restart your router if you’re using a wireless connection.
• On your computer, go to Control Panel > Devices and Printers, right-click on your HP Envy 4500 printer, and select See what's printing. Make sure the printer is set as the default printer and is not paused or set to offline.

Update or Reinstall Printer Drivers

• Visit the HP Support website and download the latest drivers for your HP Envy 4500.
• Go to Control Panel > Programs and Features and uninstall the existing HP printer drivers.
• Install the downloaded drivers and follow the setup instructions.

Printer Software Settings

• Open the HP Smart app (if installed) and check if it can detect your printer. Use it to troubleshoot and potentially resolve connection issues.
• If the printer has a display, navigate to the network settings and ensure it is connected to the correct Wi-Fi network.

3. Reset Printer to Factory Settings:

• Refer to the printer’s manual or the HP website for instructions on how to perform a factory reset. This can often resolve persistent hardware and connectivity issues.

I hope this helps.

Take care and have a good day.
