Unfortunately you have come to a dilema of the printer world. The rollers are mearly chunks of rubber, expected to last forever and pick up pieces of paper. Every time a piece of paper is picked up, it drys out the rollers, and dust covers the rollers. Here is a temporary solution.
Temp Solution: Open the printer, look for rollers, you will likely find several small black in color, rollers. You may see cracking, or white powder on the rollers. Even if you don't, here is your solution. Take a damp paper towel, and wipe each roller thoroughly. Make sure you look all around to make sure you are getting all rollers.
Longer solution: Purchase a maintenance kit for your printer. I know HP carries them for their printers (HP is the way to go with printers). They will include rollers, and little tools to obtain the rollers along with detailed instructions. If they do not make one, find one broken on ebay for 12 dollars and get that. The kit would have cost you between 12 and 30 dollars anyways.
I wish you the best of luck. Please e-mail me if you still have issues.
