Abstract

A damping device for a media feed mechanism for a peripheral device includes a media feedpath having a feed shaft and a downstream exit shaft. In one form a damping hub is mounted on said exit shaft, a resilient biasing member extending between the damping hub and the feed shaft to create a damping force on the damping hub. In another embodiment damping is provided by a brake structure engaging said damping hub. In yet another embodiment, a brake structure is pivotably mounted.
