a protective enclosure for an image - recording drum of the type used in electrophotographic printer / copiers comprises a pair of spaced guides that serve to slidably support the drum within the enclosure . such guides , when aligned with similar drum guides located within a printer / copier frame , enable the drum to be transferred from the enclosure to the copier / printer by merely sliding the drum from one pair of drum guides to the other . a mounting mechanism operates to couple the drum enclosure with the printer / copier frame to properly align the respective drum guides . by virtue of the invention , the image - recording drum can be installed in copier / printer without physically contacting the drum &# 39 ; s delicate photosensitive surface , thereby eliminating any image artifacts that may arise from inadvertent scratching or marring of the drum surface during installation .
