A document copier having an automatic document handler is able to process jobs whose number of document sheets exceed the capacity of the document feeder by including control to stop feeding sheets whenever there is less than a predetermined minimum number greater, than one, of unfed sheets remaining, so that an operator can add more sheets of the same job. Feeding can be reinitiating after the automatic document handler has been stopped, and the stopping feature can be selectively disabled so that all received sheets are fed by the automatic document handler without stopping. Generally, the document feeder will be used with a job processor which treats the last sheet in a received stack, and all preceding sheets, as a job.
