Abstract
A squeeze roller retraction assembly for use with electrophotographic copying machines of the type in which a photosensitive drum is removable from the machine, for inspection or other purposes, through an opening formed in a sidewall which opening is normally covered by a coverplate. A squeeze roller which normally engages with the peripheral drum surface has its engagement therewith automatically released once the coverplate has been dismounted from the sidewall, and also is returned to its operative position as the coverplate is remounted, to thereby prevent damage of the drum as well as a wrong usage of the machine which may be caused by forgetting to replace the squeeze roller to the operative position.
