This procedure can almost be applied to the similar 1350cnw printer (without scanner and fax feed tray). Open the back cover, release the blue tabs by lifting upwards and carefully remove any screws that are obviously holding the top cover in place (mine had already been removed and lost, I assume!). Then with a flat bladed screwdriver or similar tool, lever out the corners of the top cover. I broke the tabs of one that hold these in but they do go back with a bit of brute force and a small supply of ignorance. You will see two black screws - Do Not remove these, the cover lifts over them. Once you have the corners released, go round the rest of the back part of the top cover, releasing it from the sides and pulling the edcge up, until you can see the paper, possibly concertinered up against the roller. If you can get a purchase on the end of the concertina (or if you prefer, accordion) poke a screwdriver into the end and carefully drag it out to the side or back. Make sure you have a complete sheet and there are no tiny bits left inside. I have done this twice and no ill effects. Put the corners back as best you can, secure with tape if you have to, and tuck in the top cover as you do so. Replace any screws and relax, it should now work again. What a pity Dell don’t reveal these procedures. I guess they want to sell us another printer. Not me!
