The feed rollers and separation rollers on a laserjet 4100 are identical. Each lower tray uses one feed roller and one separation roller. If you have one lower tray you only need two rollers. If you have a 4100T then you will need four rollers. If you have a 4100T with an optional lower cassette then you will use six rollers.

Pull the trays out of the printer and look up into the printer. You should see the roller circled in red below. Simply pinch the tabs together on the left side of the roller and pull the roller out. Push the replacement roller in place and move on the the remaining lower cassettes (if they are installed). The rollers will install in the same manner.

Place the paper tray in front of you and press the tab circled below forward. Then swing the hinged piece up. Pinch the two tabs on the roller and pull the roller out. Replace with a new roller and repeat this procedure for all of the installed lower trays.
