Haven't held fiche in years), which would give you (.25 * 2400) = 600bits/wide. Assuming it's from an 8-1/2" sheet, (600 / 8.5) = 70, which would come to about 70 dpi relative scan density. A little low for OCR, but is it readable? If you need larger size, how hard would it be to project a microfiche image onto a sheet, and to scan that? You shouldn't need to make a single page image much larger than a 1" wide to get something scannable. (2400 * 1")/8.5 = 282 dpi equivelent. Probably good enough for OCR if it's not to blurry. Just thinking strange ideas. Wish I had some fiche to try.
