Just the axle on to which the ribbon is winding is pushed, and also the ribbon assembly is meant to operate with an axle-driving mechanism that reverses the course of rotation when the undriven axle reaches the point in which there is almost no ribbon left wound all around it.
An operator who judges a ribbon's ink source to become way too depleted normally manually winds the whole ribbon on to the fuller reel, releasing it from your empty one, and discarding the ribbon as well as reel on which it really is wound.
