1. Unplug the power cable from printer when the printer is powered on and wait for 20 seconds.
2. Then, press and hold # and 6 while plugging in the power cord.
Continue holding until it displays Semi Full Reset message in the front panel of the All-in-One.
The printer will turn off or shows Semi Full reset message.

The L7780 usually has a duplexer which has a rear access panel on it but this is NOT the panel that the printer detects as open.
In the L7780 anything that is connected/slotted into the rear slot/hole is considered to be the rear access panel. This means the duplexer (which is standard on the L7780) is seen as the "rear access panel".
Stand looking at the back of the printer
Inside the slot on the right side you will see a green circuit board with four metal contacts on it. Check that these are not soiled or damaged in any way. Clean if necessary.
On the right side of the dupler you will see only TWO metal pins that spring out and should make contact with two of the contact points. It's possible that these are damaged and/or broken. You may need to free, re-bend, etc... these CAREFULLY so that they stick out properly. Ultimately the goal is to ensure that the metal pins touch the appropriate contacts on the circuit board.
If all else fails, check your warranty and contact HP to see if they can provide a replacement duplexer. If the circuit board itself (in the printer) is damaged though you may need to return the printer itself.
Hope that helps.

Is this a refillable cartridge you're using or a genuine HP OEM...
If it's a CIS, refillable or some kind of cartridge which is not made by HP then chances are the ink nozzle has failed and allowed the yellow ink to leak everywhere...
There are a lot of problems with these 3rd party cartridges and I would never recommend using anything other than a refilled HP cartridge or a genuine one.
Hope that helps.
