Digital BW, The Print

Has anybody had any problems with the paper feeding mechanism on a 
Epson 2200 printer. After about 2-3 years of use, the mechanism that 
feeds the paper from the top will no longer work by itself. You either 
have to help the paper get picked up, or feed the paper in the back 
from the roll-paper input.

Does anybody know how to fix this?

Thank you
