Before you begin, you will want to place the object that you want scanned face down in
the scanner, with its corner square with the top right of the bed of the scanner. It is
marked with an arrow.
Once you have placed your object in the scanner, load a program called “Imaging”. You
can locate this program by click on
selecting “Imaging”.
and going to “Programs”, “Accessories” and
2
Once in imaging, you’ll have to go to the “File” menu and select “Acquire Image…”
Alternatively, you can press the
“Scan New” button
in one of the toolbars in Imaging, below the file menu.
3
This brings up the scanning window. This is where you can change scanning options. The
first thing you do in this window is press the
“Preview” button. Pressing this
gives you an idea of how the scanner is viewing your object.
4
Once you have your preview, click and drag a box (a marquee) around the portion of the
preview image that you want to be scanned. You’ll see a dashed box around the option to
be scanned. As you can see, I’ve selected the top portion.
These are a few tools across the top left of the scanning window that will help you orient
and display your image properly.
Marquee – defines a box around a portion of the image you want to be scanned

Auto fit – attempts to automatically marquee the image

The next part is sort of tricky, as you’ll have to choose options that will best fit your final
goal with the scanned image.
The two most important settings that affect your scanned image output quite drastically
“Color Mode” and
“Resolution”.
are
Color Mode defines how much color information you want the scanner to pick up. All of
which are pretty self explanatory, except for maybe “Text Enhanced”. Text Enhanced
would be good for scanning in a page with just black and white on it, no shades of grey or
color.
Resolution is how much detail you want the scanned image to have. Resolution is
measures in DPI, which stands for “Dots Per Inch”. The higher the DPI, the nicer your
final output will be. But be warned, if you select a really high DPI (say, anything higher
than 600DPI), your computer will act sluggish, as it takes much more processing power
to process the large image. Also, when you go to save the file, it will take up a lot of
space to store it.
NOTE – when scanning in an image (or even a document with fine detail), if you select a
preset, I would recommend checking “Magazine – Reduce Moiré” ON, as the image will
come out MUCH clearer.
6
For almost all scans though, choosing an “Image Type” preset will do you just fine
“Color Screen” – used most commonly for scanning in a color picture or color document
(but not with fine detail, as it is lost in the scan) for use in email or a website.
“Color Photo” – useful for scanning in a color picture or color documents at a higher DPI
for inserting into documents.
“Color Photo Fine” – same as Color Photo, just a higher DPI. Your prints will come out
much clearer.
“BJ Printer” – for use if you intend on printing out the image to an inkjet printer.
“B&W Photo” – same as Color Photo, only grayscale.
“B&W Photo Fine” – same as Color Photo Fine, only grayscale.
“Line Art” – useful for scanning in sketches done with a pen or pencil.
7
“Laser Printer” – when printed to a laser printer, and when the original is of black and
white laser quality, this setting will yield an almost perfect duplicate, as if you used a
photocopier.
“Fax” – useful if you are going to fax the scanned image, as it enhances the clarity of the
text at a decent DPI.
“OCR” – useful for when you want to scan in a document and send it to an OCR (Object
Character Recognition) program. OCR programs can convert an image to an editable
document.
8
Once you have selected all your options, click
“Scan”. Wait a moment for the
scanner to warm up and scan the image. Once its done, you will be put back to Imaging
where you initially started.
9
Once your back in Imaging, you might notice that your image looks a little weird, or
perhaps garbled. If this happens, make sure you are viewing the image at 100%. As you
can see above, I am viewing the image at 65.50%.
To do this, go to the zoom dropdown and select
100%.
Alternatively you can type in 100% and press
enter.

Now you have 3 choices, either print out your scanned image using the
save your document by clicking the

“Print” icon,

When saving scanned images, I would save them as .JPG format, as they take up the least
amount of space and are easily emailed. If quality is a must, then save then as a .BMP, as
Bitmap format saves all the quality, but JPEG looses quality slightly to save space.
For use on the web, you should ALWAYS use JPEG, unless otherwise requested.
