How long does it take to scan a book?
It depends on the speed and options of your scanner and the condition and size of the book. A high speed scanner with an ADF can scan a 400 page book with pages in good condition in less than ten minutes. For a standard flatbed scanner doing manual page turning, once you get into a rhythm, you can probably do a scan every 20 to 40 seconds or about 3-6 pages per minute (two pages per scan), 180-360 per hour. Allowing for glitches, short breaks, etc. a 400 page book will probably take in the region of two hours to scan.
Putting the book flat on the glass means that you scan two pages at a time. A reasonable modern scanner will scan the area of two typical pages at 400dpi in anywhere from 20 to 40 seconds–let’s call it 30 seconds for two pages. That’s four pages a minute, or 240 pages an hour. You could reasonably get through a 400 page book in two hours, even allowing for an occasional break or glitch. Of course, you should also allow time for scanning a few trial pages with different settings before you start, to decide which settings to use. Ten minutes spent here can save you hours of proofreading time. There are two big tips that can save you a lot of scanning time: If your OCR or scanner control package has a timer setting, that automatically keeps scanning without user intervention, you can forget about the screen and just keep turning the pages as needed. You should set your scanner just to scan the area the book covers on the glass. By default, your software will probably scan the full area o
