Hi @martin69126,

Welcome to the HP Support Community. 

I'd be glad to help you! 

I understand that you are having issues with Error 049834E8

The error code 049834E8 on your HP OfficeJet Pro 9012e All-in-One Printer typically indicates a firmware or hardware issue. To troubleshoot and resolve this problem, you can try the following steps:

1. Restart the Printer (Power Cycle)

• Turn off the printer by pressing the power button.
• Unplug the printer from the power outlet.
• Wait for about 60 seconds.
• Plug the printer back in and turn it on.
• Check if the error code disappears.

2. Reset the Printer

• If a simple restart doesn’t work, you can perform a full reset:
  • Unplug the power cord from the printer while it is still turned on.
  • Disconnect the power cord from the wall outlet.
  • Wait for about 60 seconds.
  • Plug the power cord back into the wall outlet and the printer.
  • Turn on the printer and see if it starts without the error code.

3. Check for Firmware Update (If Possible)

• If the printer starts normally, check for any available firmware updates:
  • On the printer's control panel, go to Settings > Printer Maintenance > Update the printer.
  • Alternatively, use the HP Smart app on your computer or mobile device to check for updates.
• Ensure that the printer is connected to the internet for this process.

4. Clear Printer Memory (Partial Reset)

If the printer is stuck on the error screen, try the following reset procedure:

• Turn off the printer.
• Unplug the power cord from the printer.
• While unplugged, press and hold the Power button for 30 seconds to discharge any remaining electrical charge.
• Plug the power cord back in and turn on the printer.

Hi @martin69126 ,

Please find the remaining steps below.

5. Disconnect USB or Network Connections

• If your printer is connected to a computer via a USB cable or network (Wi-Fi or Ethernet), disconnect all connections.
• Restart the printer without any connections.
• If the printer boots up normally, reconnect the USB or network cable and try printing again.

6. Factory Reset (If Nothing Else Works)

• If the issue persists, a factory reset may be necessary. This will restore the printer to its original settings:
  • On the printer's control panel (if accessible), go to Settings > Printer Maintenance > Restore.
  • Select Restore Factory Defaults.
• Note: This will remove any custom settings on your printer, including Wi-Fi network settings.

If the error persists after trying all the above steps, there may be a deeper firmware or hardware issue.

You should contact HP Phone Support for further assistance.
