HP DeskJet D2400 Printer Series - 'The Cover is Open' Message Displays on the Computer

Issue

If top cover of the product is open or the open door sensor is broken, the following message displays: The cover is open. The document fails to print and the product driver status changes to Door Open. The document to be printed is added to the print queue.

Solution

Follow the steps to resolve the issue.

Step one: Check the door

  1. Close the door properly. Make sure it is closed and completely seated in the body of the product
  2. Click OK to print the document.
    If this does not resolve the issue, continue to the next step.

Step two: Reset the printer

  1. Unplug the USB cable from the back of the product.
  2. Remove the power cord from the electrical outlet on the wall and the power supply cord from the product. Wait for 30 seconds and connect the power cord back to the wall electrical outlet and the power supply cord into the product.
  3. After the product has turned on, connect the USB cable to the product.
    If the error message The cover is open still displays or if the driver status still shows Door Open, continue to the next step.

Step three: Check the door sensor activator

  1. Open the top cover and inspect the plastic sensor activator found on the lower left side of the top cover.
    If the plastic sensor activator is broken, go to Step four.

    If the carriage moves away from the middle of the product, there is no problem with the door sensor. The error message disappears from the screen.
    If the Cover is Open error message does not disappear from the computer, unplug the USB Cable and reinstall the product software.
    If reinstalling the product software does not resolve the issue, go to the next step.

Step four: Service the product

Service or replace your HP product if the issue persists after completing all the preceding steps.
Go to Contact HP Customer Support to schedule a product repair or replacement. If you are in Asia Pacific, you will be directed to a local service center in your area.
To confirm your warranty status, go to HP Product Warranty Check. Repair fees might apply for out-of-warranty products.
