Pickup Foot

Release the foot from the shaft by pulling up on the tiny little arm just to the right of the foot, at the shaft. Just under my thumb nail in the picture.

Work the foot out of the printer up and over the shaft.

Clean or replace the rubber

Work the foot back in, behind the shaft. Bring the left side forward first, then the right.

Pull the foot up against the shaft to snap it into place.

Make sure the foot is pressed to the left to engage the splines on the shaft.
