Abstract

It is desirable to provide automatic or semi-automatic document feeders or document handlers, as they are variously known, for automatically feeding the document sheets to be imaged to a scanner, and merging the electronic pages scanned in into a collated electronic document for printing. Typically, such document feeders have limits set for the number of document sheets to be loaded therein at one time, e.g., 50 sheets or less, for reliable sheet separation and feeding.

It is desirable to provide automatic or semi-automatic document feeders or document handlers, as they are variously known, for automatically feeding the document sheets to be imaged to a scanner, and merging the electronic pages scanned in into a collated electronic document for printing. Typically, such document feeders have limits set for the number of document sheets to be loaded therein at one time, e.g., 50 sheets or less, for reliable sheet separation and feeding.

Disclosed is a control sequence for generating a large multipage electronic document with a scanner having a document feeder with such a limited capacity, i.e., a document feeder which can only feed a lunited number of sheets of originals in one batch or set, as is often the case with document feeders. With this control sequence, with three software commands, for start, appending, and end session, the set of original sheets can be broken up into two or more subsets and fed in two or more such batches through the document feederhager. These batches or subsets can be less than the maximum number of sheets allowed by the document feeder. The system is instructed to hold the first part of the scanned job in memory from the first batch fed until the rest of the job has been fed in to be scanned in the subsequent batch(s), and then, after the entire job has been scanned in, the later batch page images are appended to the previously scanned in batch page images from the first part of the job and send to the destination of the job as an integral docu...
