Thank you Allen for taking the time to answer my questions,

I believe there is also a scanner model that has a flat-end extension
so, the ADF prefix could make sense then, however "back", front",
duplex" would be my preferred choices.

Yes the front is the side which touches the paper tray and the
beginning seems to be the point where scanning starts. This means you
have to turn the paper on top and rotate the front to back before
placing the paper in the tray. This is really counter intuitive. Is
this hard coded in the firmware of the scanner or something of the
device driver?

I tried to reproduce the results I encountered yesterday, but the
scanner is now responding in a different way. (see the attachment)

The datasheet(1) is saying it can scan A4 paper and automatically
recognizes document size, is this not supported in the device driver?

Please see the attachment and the links(2) for the images I tried

Is it really that hard to scan A4 paper with a more then 500 Euro
scanner? So far I only have been trying to get the basis functionality
of the 100 Euro all in one HP scanner that I previous used, let alone
get the functionality I really wanted like automatic different size
business card scanning. Am I now just bitching and making no sense or
is there something wrong? I know I am a perfectionist but I need it
for the quality of the work I do.

I want to be able to just input a bunch of different sized documents
and execute the scan command and get a bunch of images returned that
contain the data on the source documents and not more and not less. So
I can process them to my other automatic systems for OCR, archiving,
DjVu, meta tagging etcetera.

Any help/advice would be appreciated,
