4.2.2 OTHER IMAGE OPTIONS

Binarization This is the process of converting a

grayscale or color image to a bi-tonal
image. There are several different methods
of performing this conversion. Two of the
options are Dynamic Threshold and

Fixed Processing.
Dynamic Threshold: Selecting

Dynamic Threshold allows the scanner to

dynamically evaluate each document to
determine the optimal threshold value to
produce the highest quality image. This is
used to scan mixed document containing
faint text, shaded background, or color
background with a single setting. If
Dynamic Threshold is selected, Threshold,
Brightness, and Contrast are not available.

4-

8

Fixed Processing: Used for black-and­white and other high contrast documents.
A single level is set to determine the black­and-white transition. The threshold is
programmable over the entire density
range. Fixed Processing sets Contrast
to 0. If Fixed Processing is selected,
Contrast is not available.

4-

Threshold Used to convert a grayscale image to a

bi-tonal image. The value ranges from 0 to

255. A low threshold value produces a
lighter image, and can be used to subdue
backgrounds and subtle, unneeded
information. A high threshold value produces
a darker image, and can be used to help pick
up faint images.
Adjust the threshold setting by dragging the
Threshold sliding bar to the left or right to
achieve the desired threshold setting.

4-1

Resolution

A good control of the resolution results a
good 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 greater
resolution takes more time to scan, and
more disk space for the scanning image.
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 only
recommended when you need to scan a
small area at True Color mode.

Choose a resolution value from the drop
down list. The default value is 200 dpi.
Available resolutions are 75, 100, 150,
200,300, 400 and 600. Or you may
choose your desired value by clicking the
box in the right side of the drop down list
and press the arrow key to select your
desired value and then click the Add
button to include it in the drop down list.

4-11

Resolution: 75 dpi

Resolution: 150 dpi

Invert Reverses the brightness and the colors in the

image. The default setting is Black on a White
background. Reverse mode is White on a Black
background. For color images, each pixel will be
changed into its complementary color at the
command of Invert.

and there is document in both the auto
document feeder (ADF) and the flatbed, then
the scan source will be automatically set to
ADF. If Automatic is selected and there is
document only in flatbed, then the scan
source will be set to flatbed.

4.3 THE COMPRESSION TAB

The Compression tab allows you to compress your
scanned image and choose the level of compression. Bi­tonal images are normally compressed using CCITT
standard called Group 4 (G4). Color and grayscale images
are often compressed using JPEG technology. Move the
JPEG Quality slider to the right or left to increase or
decrease the level of compression. Note the greater the
compression level, the lower image quality. Default is 50%.

Note that the compression depends on your image editing
application. If your image editing application does not
support the type of compression format, then either a
warning message will appear or the image quality of the
compressed file will not be acceptable.

JPEG (Joint Photographic Editor Group). This group
developed and lent their name to a file compression
standard for color and grayscale images that is widely used
by scanners, and software applications. On Microsoft
Windows-based systems, a file with the extension .jpg has
normally been compressed using this standard.

For scanning color or gray images, the following
compressions are available:

y None
y JPEG

For scanning B&W images, the following compressions are

available:

4.4 THE COLOR DROPOUT TAB

4.4.1 COLOR DROPOUT SELECTION

Color Dropout tab allows you to drop either of the red, blue,
or green color in your scanned image. If your image
contains red color watermark or background, choose the R
(Red) channel then any red watermark or background will
be removed. This feature is used to sharpen your text
when using OCR (Optical Character Recognition) software.

Note that this function supports only black & white and gray
images. Therefore, be sure to choose any black & white or
gray image type while applying this function.

4.4.2 OTHER COLOR DROPOUT OPTIONS

Advanced Processing provides two options that can
adjust your scanned image in the best optimal result.

Filter

Threshold

This value is used to determine the color
which will be dropped out. A lower value
will drop more of the selected color out,
while a higher value will leave more of the
selected color in.

Background

Level

The pixel which is higher than the
background value will be adjusted to the
lightest point. Adjust the value for both the
Filter Threshold and Background Level to
produce the best optimal result.

Example, slightly adjusting the background value
makes your text more clear.

6.1 CLEANING THE ADF

The scanner is designed to be maintenance free.
However, it still needs to be cleaned occasionally to ensure
optimum image quality and performance.

From time to time the pad assembly and feeding rollers
may become contaminated with ink, toner particles or
paper dust. In this case the scanner may not feed
documents smoothly or several documents may feed at
once. If this occurs please follow the cleaning procedures
to return your scanner to its original state.

The cleaning procedures

i). Moisten a cotton swab with isoprophyl alcohol (95%).

(Cleaner kits are available from PictureVision.)

ii). Carefully open the ADF to the left . Wipe the feeding

rollers by moving the swab from side to side. Rotate
the rollers forward with your finger and repeat the
above cleaning procedures until the rollers are clean.
Be careful not to snag or damage the pick springs.

iii). Wipe the pad in the direction from top to bottom. Be

careful not to hook the pick springs.

iv). Close the ADF unit. Your scanner is now ready for

7. TROUBLE SHOOTING

The scanner will automatically perform a simple self­test 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: Paper becomes jammed during scanning.
Answer: a) Open the ADF unit.

b) Pull out the jammed paper carefully.

c) Close the ADF unit.

7-1

Question: More than one sheet of paper were

fed into the scanner.

Answer: a) Open ADF unit.
b) Remove the multi-fed sheets of paper.
c) Close the ADF unit.
d) Flatten the corners and edges; loosen the

paper before reloading it in the paper
guide.

e) Check the feeding roller condition and

do the cleaning if necessary.

Question: Paper becomes skewed in the scanner.

Answer: a) Check the feeding roller cond ition; do the

cleaning if necessary.

b) Use the paper guide when feeding the

paper.

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.

7-2

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 SCSI cable or the USB 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.

7-3

Question: The scanner works well 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.
