Where can I find service/repair manual for HP Photosmart 7515 printer?

Cut a hole on the bottom of the printer (with Dremel tool). Drill a whole through paper feeder driving slipping gear and its shaft (I used Dremel and 0.70 mm drill). Then put a pin in the whole (I used a solid copper wire). That is it. P.S.Before drilling the gear move it ( on the shaft) toward the center line of a printer. So.the gear is fully engaged with the opposite gear, but potion of the gear is free of engagement . That is where you drill the gear and shaft. So , the pin/wire wont impede with the gears rotation. Ooops, totally forgot.Before you flip your printer to cut a whole REMOVE ink cartridges!!!!!! Update (11/10/2017):
