This is my first post to the list. I come here for advice not directly related to PG. I have a number of physical books that have had their spines cut off and I need to scan them so they can be OCR'd and stored digitally. I am encountering two problems. All of the bulk page-feed scanners I have tried have one or both of the following issues: Duplex scanning happens simultaneously, so extreme contrast changes (such as borders) from one side of the page show through (about 5%) to the other side. Remnants of glue left on the edge of a page (from the removed spine) get stuck to the inside of the scanner or feeder, ruining the scans of subsequent pages until the scanner is cleaned. Can anyone recommend a solution to either of these problems that can hopefully be applied automatically or in a batch operation? Reduction of human intervention/effort is my goal.
