The most common error that HP printer users encounter is the “Door Open” error message on the control panel of their printer or on the computer screen. Although the solution for this problem may seem simple, which is to close the opened printer door, but it actually gets complicated when all the doors are already closed. In such a case, most users don’t know what to do and how to fix this error in their HP printer. Don’t worry, because in this guide, we will tell you how to fix ‘Door Open’ problem in HP printer, but all the doors are closed.

Causes behind the Door Open Problem

There can be multiple reasons behind the ‘Door Open’ error of your HP printer. However, they can be broadly classified into two categories: door related and printer hardware related. Sometimes this error is related to the doors of the printer, but other times there can be some hardware problems due to some damaged part. We will discuss both these causes below:

1) Issues with Printer Doors

At first you would say that the doors of the printer are closed and there is no problem with the printer cartridge door, but it’s not that simple. There can be multiple issues with the cartridge door of your printer which can cause the ‘Door Open’ error in your HP printer.

• Faulty Cartridge Door: If you have a habit of frequently opening and closing the cartridge door of your printer, then its joints can get loose and the door may not shut properly. It may seem to you that the door is closed, but the printer door sensor is unable to determine that the door is closed because the door is not properly aligned with the door sensor and you will end-up seeing ‘Door Open’ error on your HP printer control panel.
• Obstructions in Door Path: Sometimes there is some unwanted substance obstructing the path of the cartridge door of your HP printer. Due to this obstruction the door of your printer will be unable to get in proper contact with the sensor of your printer and you will experience ‘Door Open’ error on your HP printer. Also, any obstruction in the door path can create a gap between the printer’s body and the cartridge door.
• Cracked or Broken Door: If the cartridge door of your printer is cracked/broken somewhere, then you are bound to experience the door open error. Sometimes the damage is more severe, like the door hinges are broken or the door locking mechanism which is supposed to lock the cartridge door with the printer body is broken or damaged. There can be several types of minor damages to the printer door.

2) Issues with Printer Hardware

Issues with printer doors are easier to detect and resolve. However, sometimes the ‘Door Open’ error on an HP printer is due to hardware damage to the printer components. Primarily there is only one hardware component which can cause this error:

• Door Sensor: Door sensor is there in an HP printer to determine whether the printer doors are closed or not. If this sensor gets damaged or broken, then even if the door is properly closed you will experience the door open error since your HP printer is not getting the confirmation from the door sensor that your printer door is closed. The door sensor is sometimes mentioned as a door sensor activator in printer hardware manuals.

As you can see that the ‘Door Open’ error can be caused due to printer door issues as well as printer hardware issues. In case, of the hardware damage, you will have to replace the door sensor of your printer, which should be done by the HP service engineer. However, for solving the error related to the printer cartridge door functioning, you can follow the solutions given below.
