SOURCE: hp officejet l7780 rear access panel

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: how do i clean the printheads on a hp officejet

hp printers have a utility program that cleans and purges the printer heads. Go to HP on your startup menu and look through the options....mine is located in the "hp solutions center".

It has an option for purging the printer heads.

Hi this appears to be part of a generic problem possibly caused due to power surges…

As recommended by HP on these types of errors:

1: Disconnect the USB cable from the back of the product, but leave the product turned on.
2. Open the cover of the product and remove the print cartridges.
3. Close the cover and wait for the Insert Ink Cartridges message to display.
4. Disconnect the power cord from the back of the product and wait for one minute.
5. Reconnect the power cord. If the product does not automatically turn on, press the Power button.
6. Open the cover and reinsert the print cartridges.
7. Close the cover. If prompted, print a calibration page.
8. Reconnect the USB cable, and try to print a print job from the computer.

If this works, please grade the answer... If the steps don’t work I would recommend you check with HP.
