paper loading
manual/automatic
With manual loading, you position the original in the slot and then
press the down button on the scanner.
With automatic loading, the scanner detects and loads the original
as soon as you insert it.
See how do I define scanner setup options? on page 39.
side/center
You can load your original into the scanner from the scanner’s
center or side. Center loading is handy with standard sized
originals (A4, A3, E-size, and so on). Center loading is strongly
recommended when scanning thick originals such as cardboard or
foam-board. Side loading is convenient when you want to use the
ruler imprinted near the scanner’s insertion slot to read the width.
See how do I set preferences? on page 44.
delay factor
A delay factor can be set for automatic paper loading giving you
time to position the original correctly.

correction factor in scanning
This option allows you to fine-tune the scanner’s vertical precision
setting and mainly refers to copying where the relationship between
lengths on the original must be kept in proportion. Examples are
engineering drawings, maps, and perhaps even some types of art
posters.
During scanning, an original image is digitized as it is propelled
through the scanner. One at a time, thin strips of the image are
processed as they pass the cameras. Vertical precision is directly
affected by the speed in which this happens. Inaccurate vertical
precision makes vertical lines in the scanned image become longer
or shorter than the same lines in the original. The vertical scan
accuracy is adjusted and set mechanically during production of the
scanner. This setting is extremely precise and more than adequate
for most purposes.
