Error message 0X83C0000A NOS_LOADER_APP

[Pistachio2]

I've tried a semi and hard reset and neither has worked. Any other suggestions?

@Pistachio2, Welcome to HP Support Community. 

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

The error code 0x83C0000A NOS_LOADER_APP on HP printers is a critical firmware boot error, often meaning the printer is unable to load its operating system. Since you've already tried semi and hard resets, here are a few advanced steps to try before determining if service is required:

Power Cycle with Minimum Configuration

• Turn off the printer.
• Disconnect all cables, including:
• Power cord
• USB or Ethernet
• Remove any memory cards or USB drives.
• Wait 2–3 minutes.
• Reconnect only the power cord, directly to a wall outlet (not a surge protector).
• Turn on the printer. 
  If it boots normally, reconnect the other cables one at a time.

Firmware Recovery via USB (if supported by model)

This may only work if the printer supports "Firmware Recovery Mode" (you may see a USB icon, “Ready for update” message, or a blank screen with the power button lit). 
 

Steps:

• Go to the HP support page.
• Search your printer model.
• Download the latest firmware update tool (usually ends in .exe).
• Insert a blank USB drive (FAT32 formatted).
• Use the HP firmware tool to extract firmware to USB.
• Plug the USB into the printer while it's off.
• Turn on the printer and wait to see if it triggers a firmware recovery update.

Use HP Print and Scan Doctor (for connected printers)

If your printer still connects via USB or network, try:

Official HP Print and Scan Doctor for Windows | Free Download hppsdr.exe

Sometimes it can detect and prompt recovery options, even for firmware issues.

I hope this helps. 

Take care and have a good day.

What if my computer doesn't have a USB drive? Is there an adapter for that?

[Pistachio2]

Thank you for the suggestions. I tried unplugging it and plugging it back in, but that didn't work. As far as I can tell, it doesn't have a USB port, so I wasn't able to try your other suggestions. I'm afraid it's a goner, but I'm not sure.
