Can you help me fix my printer?

I have a Lexmark X-5150 printer. (It's a 3 - in - 1 combination printer - scanner - fax). While I was printing something, a sheet of paper went through the printer crooked. The page printed O.K. (but at an angle), and then I got a message saying the printer was jammed. I opened it and didn't find anything jamming it (the crooked paper had gone all the way through the printer). Now, when I try to print anything, the printer accepts the paper and it runs through, it sounds just like it should when it is printing, but it comes out blank, with nothing printed on it. The cartridges are only a few days old and have ink in them. The computer does not indicate there are now any problems with the printer. I have gone through the troubleshooting procedures that came with the printer software and I have tried to print test pages, but they always come out blank.

I think that the crooked sheet of paper damaged something in the printer, and I would appreciate any help in fixing it.
