Best Settings for Scanning Old Invoices (dot matrix impact not hard enough)

May 11, 2015

I have the wonderful task of scanning several thousand of our old invoices dating back to 1970 many of which are on a yellow carbon copy paper printed with a dot matrix. We have about 2000 or so that are very light and not scanning well even with changing around the darkness, color, contrast, sharpness, dpi, etc.

I've come to the conclusion that perhaps a color extraction might be the best option but the Lexmark only allows for 1 of the 3 primary colors to be taken out a time. i.e. R, G, B.

My ultimate goal is to make the file readable using OCR in Adobe acrobat pro so I can "search" for invoice numbers. Everything else is somewhat not needed for indexing purposes.

2-1/2 hours on tech support didn't help much.

Does anyone have a clue on how best to get the lightly impacted type to best show up?
