Hi Adam,
I suspect that you are talking about the tray 2 pick up roller. Here are the directions for that:
1.)Remove paper tray
2.)Unlock left locking tab and rotate forward untill bushing slides off
3.)Remove black plastic roller retaining bracket
4.)Slide roller to the left untill right side of shaft clears the bushing
5.)Lift roller out of printer
6.)Place spring loaded end of roller shaft into left housing
7.)Slide roller to the right and rotate until roller locks into pickup shaft
8.)Reinstall black plastic roller retaining bracket. Left side first.
9.)Reinstall left bushing and lock into place
Let me know if you where sucessfull,
Printer Piete
