In an automatic document feed (ADF) device, a machine operator places a stack of documents in the device, turns the machine on, and documents are fed in a serial manner to a processing station. To feed the documents, a feed wheel is lowered onto the top of the stack to move the top sheet into the grip of nip rolls. At this time both the feed wheel and nip rolls are deactivated until the machine indicates that it is ready for the next document. In that manner, next documents are staged at a queuing position, ready for movement to the processing area. Should the operator realize a mistake and attempt to remove the stack, the staged document is removed from the nip rolls, thereby deactivating a sensor which causes the feed wheel and nip rolls to resume feeding activity.
