4-1

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.

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.

4-4

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 24­bit true color image.

Halftone Image

4-5

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 photo graphs.

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

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
true-to-life quality to the image. Choose 24-Bit Color if you
are scanning color photos.

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

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.

6-4

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.

seem much thicker than those of the
original.

Answer: Use the Brightness or Threshold

setting to adjust the line art image.
