4.2 DETERMINING YOUR
RESOLUTION
A good control of the resolution results a
satisfactory detail of an image that scans. The
resolution is measured by dots per inch(dpi).
Normally, the greater the dpi number, the higher
the resolution and the image file size.
Be aware that the greater resolution takes more
time, memory and disk space, therefore, up to a
certain degree of dpi, the resolution will not visually
be improved, on the contrary, it makes your files
more unmanageable.
Resolution: 50 dpi
Resolution: 100 dpi
4-2
Tips:
1. For your information, an A4 size color image
scanned at 300 dpi at True Color mode
consumes approximately 25 MB of disk space.
A higher resolution (usually means over 600 dpi)
is recommended only when you need to scan a
small area at True Color mode.
2. You can also refer to the following table to
choose a proper resolution while applying your
image to other application.

4.3 SELECTING A PROPER IMAGE
TYPE
Select image type through the mode from
the scanner user interface for your own purpose.
Each image type is described as follows:
Line art(Black and White)
LineArt presents the image in black and white
only and there are no intermediate shades of
gray in between. That means each pixel of
the image is 100% black or 100% white.
LineArt is the best choice of image type if you
want to scan text, pen or ink drawing. Since
only 1-bit of black or white information is
required for each pixel*, the disk space
required for saving lineArt image is only about
1/24 of that required to save 24-bit true color
images.
4-4
Lineart Image
*Pixel: A combination of two words: picture and
element, a pixel is a single dot on a computer
display or in a digital image.
4-5
Halftone
In addition to the black and white display,
Halftone simulates gray scale by using
different size of dots. Particularly when you
view the image at a certain distance, it looks
very closely like a gray image yet it consumes
the least disk space. Halftone is the picture
that we usually see in newspapers or
magazines. Since Halftone is one type of
black and white image, the disk space required
to save a halftone image is 1/24 of that
required to save a 24-bit true color image.
Halftone Image
4-6
8-Bit Gray
A single-channel image consists of at least 256 shades
of gray. An 8-bit scanner produces a grayscale image
with 1024 shades of gray between pure black and pure
white. Choose this option if you are scanning black and-white photographs.
With 8 bits of color information per pixel, the file size of
an image is eight times larger than a Black and White
image and 1/3 the size of a 24-Bit Color image.
Gray Image
4-7
8-Bit Color
an 8-Bit Color image provides 256 color hues in the
image. The file size of a 256 color image is 1/3 the size
of a 24-Bit Color image.
8-Bit Color Image
24-Bit Color
A 24-Bit Color image consists of three 8-bit color
channels. The red, green, and blue channels are mixed
together to create a combination of one billion colors
which give a more tr ue-to-life quality to the image.
Choose 24-Bit Color if you are scanning color photos.

7. TROUBLE SHOOTING
The scanner will automatically perform a simple
self-test each time it is turned on. This will help
spot major system errors in the scanner itself.
When the test is initiated, the READY LED is
flashing. When the test is completed, if no error
occurs, the READY LED is steadily on.
If you have problems with the operation of your
scanner, please check the following
troubleshooting hints.
7.1 QUESTION AND ANSWER
Question: The LED indicates that the
scanner is ready, but the
scanner does not respond to the
scan command from the host
computer.
Answer: a) Please check if the signal
cable is firmly seated, and
invoke the scan command again.
If there is still no response,
please reset the scanner by
turning it off and then on again,
and reboot your host computer
as well.
b) Check if the driver is correctly
installed.

Question: When I power on the scanner, it
makes noises and will not stand
ready.
Answer: There are two possibilities:
a) You forgot to remove the
shipping switch from the
scanner. Please remove the
shipping retainer first.
b) You did not place the
scanner on a flat desktop
surface. This may cause the
scanner to function improperly.
Question: When I power on the scanner,
the lamp does not light.
Answer: The possibilities are as follows:
a) The lamp is out of order. In
that case, contact your
authorized local dealer to
change the lamp. The life time
of the lamp is about 5000 hours.
b) Check whether the power
LED on ADF cover steadily
lights or not.

If it flashes, the power adapter
malfunctions or the main board is
short-circuited.
Contact your authorized local
dealer to replace the power
adapter or main board.
Question: Getting image from the scanner is
not a problem, but when scanning,
the scanner or system will often
crash.
Answer: Please check
a) If the cable is firmly seated;
b) Only two SCSI terminators can be
connected to your SCSI daisy chain.
One is at the end of the SCSI device,
and another is already in your host
adapter.

Question: The scanned image always
comes out to be too dark.
Answer: a) Use your application to
modify the Gamma setting to
2.2 and 1.8 for your printer and
monitor respectively.
b) Use Brightness setting
from the TWAIN user
interface to get a brighter
image.

otherwise, but for the line art,
the lines scanned seem much
thicker than those of the
original.
Answer: Use the Brightness or Threshold
setting to adjust the line art
image.
