Abstract: A document production apparatus includes a plurality of operator-selectable features, at least two of which mutually conflict and differ in level of assigned priority. A lower priority feature is automatically deselected when a conflicting higher priority feature is selected. The lower priority feature is automatically restored upon subsequent deselection of the higher priority feature. The restoration system either effects restoration of the lower priority feature or leaves the lower priority feature deselected based on a history of operator interactions between selecting and deselecting said higher priority feature. The lower priority feature may have a plurality of option configurations, and the lower priority feature is restored with the same option configuration as existed before the conflicting higher priority feature was selected.

Abstract: A subprocess is useful in start-up and shutdown of electrophotographic apparatus of the type designed to tone discharged areas. During the subprocess, a photoconductive member passing through a toning station is subjected to an electrical field tending to inhibit toning even of discharged areas. This permits discharging of the photoconductive member as part of shutdown, start-up or sitting idle. Preferably, the photoconductive member is uniformly discharged directly before the toning station which reduces pickup of developer carrier as well as otherwise benefiting the member.
