4. Scanner Operation & Document Printing
There are two types of application software interface to use with
AV100III color image scanner. They are TWAIN and ISIS.
TWAIN is the most popular interface among image-editing
application software, while ISIS is most popular among archiving
application software.
Scanning Images from within an Application (TWAIN)
Open your application and choose Select Source from the
File menu. If the Select Sourcemenu options are not
available from the File menu, see the user’s guide of your
application to learn how the TWAIN link is used.
A dialog box appears containing the different TWAIN
sources you can choose to bring an image into your
application.
Select Avision Sheet-fed as the source.
You need to select Avision Sheet-fed for just once except
when you have used the dialog box to select a different
source. In that case, you will need to select Avision Sheet-
fed as the source again before you can resume your use of
AV100III color image scanner.
Do Calibration: Place a sheet of white, A4-size paper on
the ADF and press the Calibration button to do
calibration. This should be done each time you power on
the scanner to use. Also, It is suggested you do it after the
scanner has been powered on for 2 minutes, so that the
lamp may have enough time to warm up. Or you should

do this whenever the scanned image seems to be too dark.
Place the image to be scanned face down on the scanner.
From the File menu, select Acquire.
Avision Sheet-fed TWAIN user interface will pop up on
the screen. Click on the Prescan or Scan button to get
the image.
The TWAIN user interface:

4.1 Image Type
You can select the Type menu for the mode you want to use with
your document or image.
Line art
Line art includes only black and white areas.
There are no intermediate shades of gray in
between.
Halftone
Halftone simulates different shades of gray by
varying the threshold value of a matrix.
Error Diffusion
While taking up but a minimum storage space,
error diffusion gives good image texture and
excellent image details.
Gray (256 levels gray scale)
Scanner recognizes each point in the image as a
shade of gray (continuous tone). 8-bit gray gives
more detailed information about the image.
True Color (16.7 million colors)
Color image have continuous tones along with its
color hues.

Note: For best OCR and article print-out effect, we recommend
the scanning parameters to be that of 300 dpi, black and
white mode. To scan pictures or photos, the color or gray
scale mode is necessary But then, these modes invariably
take up much more disk space. An A4-size color image
scanned at 300 dpi, for instance, takes up as much as
24MB of disk storage space. To save disk space, then,
we suggest you set the scanning resolution at 100 dpi for
those images intended for screen display use only, now
that a scanning resolution of 100 dpi can do quite all right
for the said purpose.
4.2 Resolution Control
Resolution: The number of dpi (dots per inch) that AV100III
uses for a scan.
