Are you trying to print a document to a paper size you do not have loaded? This is quite typical if you trying to print a document that is legal size, and you have letter size paper inserted, for instance.
Might need a bit of a clean. I'm not sure about that model but if you can get to the rollers easy enough, give them a wipe with a cloth thats been dampened with soapy water. If they're not turning at all then it might be a sensor, even giving it a little bit of a blow should clear any dust from it. Printers are prone to dust because paper is full of it, particularly the cheaper kind as the fibres break down in the packet, if you can get a bendy straw and blow gently around in the paper tray, but only if the rollers arent working.
