Plustek or WideTEK 12 - speed
 

Hi
Is that right that
https://www.adorama.com/icdpa300.html
Plustek OpticBook A300 Large Format and Book Scanner, 12x17"
--- Scan Speed
2.48sec @ 300dpi, A3, Color Mode
2.10sec @ 300dpi, A3, Grayscale/ B/W mode
----
or
Image Access WideTEK 12
--Full Scan in less than 3 seconds
IS THIS REAL?
I do have Epson 11000XL,
and enjoy scanning of 1000's images..
Each image is 12x12 inches
each image is scanned at 300dpi and 500%magnification
SO my copies are more than 17000 pixels high/wide.

to get such copies I HAVE TO wait.. no less than 8 minutes
prescan, scan and transfer via USB 2.0 to the computer.

during my 5 hours job I was able to scan no more than 30 images.

so.. how come they publish "scan speed , full page in 3..4 seconds..

Am I missing something?
or they do great commercial job?
