Printer says printer door is open

[Kate_123]

My printer is telling me one of the doors is open and so it will not print. I have opened, closed, unplugged and shut off the machine in a million orders and nothing is working. 

I dont think we had a power outage and I dont think there was a paper jam. I think it happened when switching my ink cartridge.

Reset the printer-

1. Turn the printer on, if it is not already on.
2. Wait until the printer is idle and silent before you continue.
3. With the printer turned on, disconnect the power cord from the rear of the printer.
4. Unplug the power cord from the wall outlet.
5. Wait at least 60 seconds.
6. Plug the power cord back into the wall outlet.
7. Reconnect the power cord to the rear of the printer.
8. Turn on the printer, if it does not automatically turn on.
9. Wait until the printer is idle and silent before you proceed

Update the printer firmware

Download available firmware updates from the HP website

With the printer on and connected to the computer, go to HP Customer Support - Software and Driver Downloads, and then identify your printer. Look for and install any available firmware updates.

For more information, go to Updating or Upgrading Printer Firmware.

Also, check if there is any obstruction in the carriage path.
