HP 6978 Printer says door open but the door is not open

[Twistedmyriad]

I just replaced the ink cartridges in my printer. Now when I close the top, it says on the display that the door is still open. It’s not open. I’ve tried unplugging and replug going and moving the toggles around to no avail. I can’t do anything as long as the display shows that the door is open.

@Twistedmyriad, Welcome to the HP Support Community!

I understand you are not able to use the printer due to this error. Let us try these steps:

Reset the printer

1. With the printer turned on, disconnect the power cord from the rear of the printer.
2. Wait at least 60 seconds.
3. Reconnect the power cord to the rear of the printer.
4. Turn ON the printer, if it does not automatically turn on.
5. Wait until the printer is idle and silent before you proceed.

Note: HP recommends connecting the printer directly to a wall outlet rather than a surge protector or a power strip.

Check the cartridge door for obstructions. Close the cartridge door completely.

If the error persists, I'm afraid this is a hardware failure. we cannot perform a factory reset as the printer is stuck at this error. Please reach out to the HP Technical Support team in your region regarding the service options for your printer.
