The IS520 will scan fold out pages directly in most cases. For the REALLY long pages, I scan them in overlapping sections and append a letter to the page number. The first piece is the left side of the page, so as you page through the document the overlapping sections scan across the long sheet left to right. Variable width documents add another level to the scan directory A convention I came up with a long time ago was to add '_number' to the file name. Changing scanning size is fairly easy between sections (changing the scan width, normally) in the program. So, if you scan a doc that has an 11x17 page, you'll end up with the following directories foo_f foo_b foo_f_1l (the 'l' is a marker that let's me know it's a long page) foo_b_1l foo_f_2 foo_b_2 ..and on an on for all the alternating page sizes Then I have to flip the filters around for all the differing page sizes and orientations Eventually, this produces sequentially numbered tiffs of differing sizes which are then 'tumbled' ..also forgot that I rotate 8x11 pages to 11x8 if the page has horizontal data on it. DEC tech manuals are the worst.. they will often have a single 11x17 page so I'll end up with dozens of directories that need to be manipulated.
