The new automatic capturing mode in PFC3 may be the first that truly works as it should, but requires a little understanding to master it
Automatic scan initiation or "capturing" is an important prerequisite for a serious book scanner. With it, one has to just focus on flipping the pages and nothing else. All the machines that we know of have a button to initiate manual capturing and some of them have a timer mode whereby capture happens at fixed intervals. Timers greatly reduce the pain of having to hit a button for every single page to be scanned, especially when both hands are busy keeping the book open at the same time. However it has a drawback - you have to follow its pace.
