Hi @Jesús_Alvizo ,

Welcome to The HP Support Community.  

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

I understand you are facing an issue with  your HP OfficeJet Pro 9020 All-in-One Printer is stuck on the startup screen with a black screen, white lines, and a full loading bar, follow these steps to troubleshoot the issue:

1. Perform a Hard Reset

• Turn off the printer and unplug it from the power source.
• Disconnect any USB or Ethernet cables.
• Wait for at least 2-3 minutes.
• Plug the printer back into the wall outlet directly (avoid power strips).
• Turn the printer back on.

2. Check for Screen or Power Issues

• Ensure the power cable is securely connected and not damaged.
• If possible, try a different power outlet.
• Observe if the issue persists or if there are changes in the display.

3. Enter Diagnostic Mode

• Turn the printer off.
• Press and hold the Power button and Cancel button (or a similar button combination specific to your printer model) simultaneously.
• Release the buttons when the printer powers on.
• If the printer enters diagnostic mode, follow the on-screen instructions or perform a firmware recovery.

4. Update or Reinstall Firmware Update the firmware on an HP printer

• If the printer is recognized on your computer, update its firmware:
  1. Download the latest firmware for HP OfficeJet Pro 9020 from the HP website.
  2. Follow the on-screen instructions to install the firmware.

5. Perform a Semi-Full Reset

• Access the Support Menu:
  1. With the printer off, press and hold specific key combinations (like Power + Cancel) to access the support menu.
  2. Look for an option to reset the printer.
• Be aware this may reset your printer to factory settings and require you to set it up again.

6. Test Without Network or Connection

• Disconnect the printer from your network:
  • If connected via WiFi, disable your router temporarily.
  • If connected via Ethernet, unplug the cable.
• Restart the printer and check if it initializes correctly.

7. Check for Hardware Faults

• If the above steps fail, the issue might be hardware-related (e.g., a corrupted display panel or internal component failure).

I hope this helps. 

Take care and have a good day.
