Printer help?

I think my printer's drive wheels are out of place or something, because it will not take the paper through the feed. I tried to remove the back to figure it out, but even though I removed all of the screws, I cannot manage to remove it. I have a Lexmark X2500, by the way.

Replace the printer with something other then a lexmark.

Yeah, I wish

EDIT: Nevermind, I got it fixed. Yeah, one of the drive wheels popped out of place. I didn't have to open the back up, I just managed to reach it with a pair of pliers.
