Yesterday, I was going to print a document, when the first of the pages got stuck in the printer. I pressed the button on with a red cross on it, and the stuck paper got out. But now all of the alert lamps (the "Color", "Black/photo" and "Paper" lamps) are on!. But I have only printed a couple of pages; the inc cartridges where new just a few days ago. And the seven-segment display says "E", indicating that something is wrong. But what is wrong? I have almost not used the printer yet and it is already giving me trouble.
