The book2Net V-Scan Cobra does not use automated page turners; a human must flip each page manually as the images are being made. Book2Net reports that the Cobra V-Scan does not damage the pages in the manner of some of the automated page turners.
If you have a delicate and rare book, would you want an automated robot turning the pages for you, or would you prefer a trained human to do the work? This is especially important when the pages are stiff or brittle and may not turn easily when using a robotic device.
In fact, the robotic page turners cannot operate in a truly unattended fashion. A human operator must always be nearby to handle jams or any situations in which the pages do not turn smoothly.
