load
With this option you can select whether to load your original in the
center of the scanner or aligned to the right. See loading
preferences on page 44.
auto-size method
There are two methods the scanner software can use to detect the
length of the image: Paper detects the end of the paper by
mechanical means, while Image performs a prescan of the image
and uses software to work out the length of the prescanned image.
The Paper method is quicker because it doesn’t require a prescan;
but the Image method may be more accurate (if the paper is longer
than the image).
limit auto-detect scan length
This option is provided so that you can set a maximum to the auto-
detected length of an image.
