This can be an issue with one of the faulty sensor across the printer.
Please check if you are able to print from tray 1, e.g. a configuration page.
A config page can be printed by holding the Green Button and releasing it as soon as the Triangle light comes on. This would take approx 5 secs.
If the printer is able to print from tray 1, then it could be an issue with the tray 2 pickup sensor.
Check if the tray 2 pickup sensor ( a black plastic piece to the right of the tray 2 pickup roller) is moving freely (front and back), also check if tray 2 pickup roller is not able to rotate completely.

If the tray 2 sensor is not moving freely and of the pickup roller is rotating completely, then reseat the pickup roller.

Are you positive that this is a 'roller' problem.  Black smudges usually indicate a drum problem (your toner cartridge).  If you pull it out, you'll see a flap that should move back and forth.  If you move that flap, you'll see a shiny cylendar.  That's the drum.  See if you can see any marks on it (don't touch it with your hands.) 

The problem is, it's hard to tell whether or not it's the drum just by looking.  Your best bet is to see if replacing the cartridge takes care of the problem.
