I wanted a one week holiday weitestgehent all the old documents of study and training digitize. The result is approximately 25,000 scans, created in a few days. Entire folders can be (as long as they are from and the like freed paperclips) scan in a short time. Depending on paper thickness fit different numbers of sheets in the feeder to avoid paper jams and overlapping messages I have placed each leaf 20-35. Are scanned automatically print on both sides of the leaves, causing the annoying turning omitted. The given 25 pages per minute (double sided and in color) could go.
Most of the problems caused by operating errors (the leaves stuck together, stuck sticky note, folded sheets, ...). Should conserve alone around the unit to scroll through the paper to be scanned once before. Overlaps (as glued notepad) are automatically detected and reported as a rule. The scanned pages look really good, here and there, there are blemishes. Thin lines or very bright colors can be applied to the scan sometimes only poorly or not at all recognized. Automatic Color Detection overlooks partially colors (colored notes on one side are partially scanned black). Once were streaks in the images, cleaning the device has helped here. These errors are but as I said very rarely occurred.
For software, I can not say much. Hochgeschraubt quality and converted to JPG Scan, otherwise nothing changes. From a certain number of images, however, you should empty the images folder, then the application will be much slower and stops responding partially. The software tries to rotate the pictures in the reading direction, but there are some other pages you must rotate manually later. Empty backs are automatically recognized and not stored. In typical school paper (checkered, lined), or perforated sheets are unfortunately regularly the blank backs stored (because it is not "empty").
So summarized: A small miracle scanner for all who regularly need to scan or or have to scan all the mountains. Small flaws have probably all devices.
