Dude, you’re destroying your own arguments. This makes perfect sense if the certificate was unbound and placed flat on the scanner bed, but it would not work with someone holding a bound volume that was 500 pages thick, trying to hold it flat on the scanner bed. No one is going to hold that and simultaneously try to enter the dimensions of the image they were scanning.
“No one is going to hold that and simultaneously try to enter the dimensions of the image they were scanning.”
Which is why I would type in the dimensions and other settings before I placed the bound volume on the scanner bed. In the similar sized document (the sheets were legal size -14”x8.5” in landscape, which made it tougher) that we copied, the results were actually quite clean and well aligned.
And of course, there’s those textbooks in college that I might have somehow managed to accidentally drop onto a scanner and just happen to hit the copy button...
