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.

SOURCE: Error: rear access panel open, but it's not and now it won't print. Help!

Check VERY closely edges, rollers etc, you likely have a small shard of paper mucking up the works.
