The above figure shows a belt-type electrophotographic copier wherein a photoconductor (PC) belt exits a drive drum and is bent in a concave configuration by a vacuum column. Whenever the electrophotographic copier is in operation, vacuum is attached to the vacuum column and pulls the belt into the column. However, in a down situation the belt tends to remove itself from the vacuum column. In order to retain the belt in the column, a pair of knobs are positioned, one on each side of the vacuum column, to hold the belt therein.
