My HP Photosmart 812 has stopped taking pictures.
No matter what I do, what setting I use, change the batteries, trying different memory cards, etc., when I take a picture, I get a black image. Nothing.
Sometimes, if I remove the batteries and let the camera sit for a couple of days before replacing them, the camera will take ONE ore TWO images before returning to my problem: black, empty pictures. NO IMAGES.
Any ideas as to why this may be happening?
