SOURCE: HP Officejet Pro L7780 constantly gives false"paper jam" error
Step 1:
======
The rollers should be cleaned if the paper fails to feed smoothly into the unit. All document and media rollers should be cleaned using a lint-free cloth lightly moistened with water.
1. The unit must be powered down and the power cord unplugged before cleaning the rollers. This will allow the rollers to be turned by hand in most cases. The paper should also be removed before cleaning the rollers.
2. Remove the rear access door to access the rollers. Clean any dust and debris from the rollers.
3. Open the unit and check the four small metal paper rollers (not the rubber rollers) in the interior of the unit. They should be clean and move freely. If these are not bright and shinny or have buildup on them, they should be cleaned. Also clean any dust and debris off of the rubber rollers.
4. Close the unit and reattach the rear access door.
5. Plug the power cord back in and power the unit up. It should reinitialize for about 20 seconds.
6. Print another extended self-test page.
Step 2:
======
==== Partial Reset ====
Press and hold # and 3 button on the unit while plugging in the power cord.
Note: For models that are not fax capable, press Plus (+) instead of #.
==== Semi Full Reset ====
Press and hold # and 6 button on the unit while plugging in the power cord.
NOTE: For models that are not fax capable, press plus (+) instead of #.
==== NVM RAM Reset ====
Press and hold OK and Cancel button while plugging in the power cord

Try This :
Connect the printer directly to the wall outlet ; not through any Power strip
Then Unplug the Power cable from the back of the printer
Keep on tapping the power cable for next 30 seconds
Plug in back the power cable;
Open the rear access door and you will get to see some rollers
Clean the rollers with a Lint free cloth Moistened with some distilled water
Try to do a copy if still it doesn works
Then Unplug the Power cable from the back of the printer
With one hand press and hold down the (#) and the (6) button and with the other hand plug in back the power cable ; it will do a Semifull reset on the printer; This will take some time ; Follow the instruction on the screen;
If still it doesn't work then you need to contact HP ;

Unplug the power cord and open the cover and remove all the cartridge and try to look I inside around the roller and try to manually roll the roller and if you can see the paper try to pull is slowly.
