Large scan jobs

ok, our DF holds 220 pages at one time.  If one of my accounts wanted to do this I would program in a batch feed mode. 

First fill the document feeder, when the document feeder empties the system will them prompt you to put the rest of the originals in the feeder and then continue the scan job until all of the documents have been scanned.

Does this help?

yes this helps however I believe the problem may be memory capacity. Is any manufacturer touting the ability to scan large files on their mfp?

I don't know of any MFP manufacturer that touts that's ability, however our Ricoh's seem to be able to do it with no issues,
