Hi @hamlinda ,

Welcome to The HP Support Community.  

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

I understand you are getting the "access door open" error on your HP ENVY 4500 e-All-in-One Printer may indicate that the printer believes the cartridge or access door is open, even if it appears closed. Here are some steps to troubleshoot and resolve this issue:

1. Check the Access Door

• Ensure the cartridge access door is completely closed.
• Press down gently but firmly to ensure it's latched securely.

2. Inspect the Cartridge Area

• Open the access door and check for any obstructions, such as:
  • Loose bits of paper.
  • Dirt or debris around the hinges or sensors.
• Clean the area gently if needed.

3. Verify Cartridge Installation

• Remove the cartridges carefully.
• Reinstall them, ensuring they are seated properly.
• Close the access door after reinstalling the cartridges.

4. Restart the Printer

• Turn off the printer and unplug it from the power source.
• Wait for about 2–3 minutes.
• Plug it back in and power it on.

5. Check for Sensor Issues

• The printer has sensors that detect whether the access door is closed. If these are misaligned or dirty, the error may appear.
• Look for small switches or sensors around the edges of the door or cartridge bay.
• Clean them gently with a soft cloth.

6. Update Firmware Update the firmware on an HP printer

• Ensure the printer's firmware is up to date. Use the HP Smart app or visit the HP Support Website to download and install the latest firmware.

7. Reset the Printer

• Perform a factory reset if the above steps don't resolve the issue:
  • Disconnect the power cord while the printer is on.
  • Press and hold the power button for 30 seconds.
  • Reconnect the power cord and turn the printer back on.

8. Inspect for Physical Damage

• Check the access door and surrounding areas for any visible damage or broken parts that might prevent the door from closing properly.

9. Test Printing

• Once the error is resolved, print a test page to confirm functionality.
