Query: Dark Shadow

I ordered this for when my toner ran out. I just opened it and put it in the printer 12/08/2012. Every sheet that printed had a dark shadow all over the paper. I put my old cartridge back in to make sure it was not the printer itself. The old cartridge had enough toner still to print a very clean & white copy. I put the new one back in and the dark shadow covered the page again. Repeated the process with the old cartridge - clean. Thought I would save money buying this toner. Not so much. Probably too late to send it back and not worth the postage.
