Hi @Home128,

Welcome to HP Support Community.

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

If you're having trouble upgrading the firmware on your HP OfficeJet Pro 8600 N911a, here’s a detailed troubleshooting guide to help you resolve the issue:

1. Verify Compatibility

• Firmware Version: Ensure that the firmware version you’re trying to install is compatible with your specific printer model (HP OfficeJet Pro 8600 N911a).

2. Check Internet Connection

• Network Stability: Ensure your printer is connected to a stable network. A poor connection might interfere with the firmware update process.
• Wi-Fi or Wired: If using Wi-Fi, consider connecting your printer directly to your router via an Ethernet cable to ensure a stable connection during the update.

3. Use HP Smart App for Firmware Update

• If you haven’t already, download the HP Smart app from the HP website or the app store for your operating system (iOS or Android).
• Follow the instructions to install the app and open it.r:
• Make sure your printer is added to the HP Smart app.

Check for Firmware Updates:

• Go to the app’s Printer Settings or Printer Maintenance section and check if there are any firmware updates available.

4. Update Firmware via HP Support Website

• Go to the HP Support website and search for your printer model (HP OfficeJet Pro 8600 N911a).
• Navigate to the Drivers & Downloads section.
• Look for the latest firmware version for your printer model.
• Download the firmware update file.
• Follow the on-screen instructions provided with the firmware update file to install it on your printer.

5. Manual Firmware Update

• Download the firmware file from the HP support site or any trusted source.
• Copy the firmware update file to a USB drive formatted in FAT32.
• Insert the USB drive into the printer’s USB port.
• Follow the instructions provided in your printer’s user manual to initiate a firmware update from the USB drive.

6. Check Printer Status and Errors

• Check Printer Display: Ensure there are no error messages or warnings on the printer’s display.
• Reset Printer: Sometimes performing a hard reset can help. Turn off the printer, unplug it for about 60 seconds, plug it back in, and turn it on.

7. Verify and Clear Print Jobs

• Clear Print Queue: Make sure there are no pending print jobs that could be interfering with the update process.

I hope this helps.

Take care and have a good day.
