4.3 Resolution Control

Resolution: A good control of the resolution results a
satisfactory detail of an image. The resolution is measured by
dots per inch(dpi). Normally the greater the dpi number, the
higher the resolution and the image file size. Yet 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.

5. Maintenance

5.1 Cleaning the Copyboard Glass

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

The scanner document glass may be contaminated with ink, toner
particles or paper coatings. As a result, the scanner needs to be
cleaned occasionally particularly if the scanned image looks
smeared.

The cleaning procedures (See Figure 5-1)

1) Open the document cover.

2) Soak a cotton swab with some isopropyl alcohol. (95%).

3) Wipe the copyboard glass by moving the swab from side to

side. Repeat this step until the whole copyboard glass is
cleaned.

4) Close the document cover. Your scanner is now ready for

use.

6. Troubleshooting

The scanner will automatically perform a simple self-test
each time it is turned on. This helps spot major system
errors in the scanner itself.

During the test, the READY LED and ERROR LED will light
on and the scanner reading head will move a bit forward.
Once the test is finished and if no error occurred, the READY
LED will stay solid and the ERROR LED will extinguish and
the scanner reading head will back to its leftmost position.

If you have problem with the operation of your scanner,
please check the following troubleshooting hints.

6-1

6.1 Questions and Answers

Question: The LED indicates that the scanner is ready, but

the scanner does not act to the Scan command
from the host computer.

Answer: Please check that the signal cable is firmly seated,

and invoke the Scan command again. If there is
still no response, please reboot the host computer
as well as reset the scanner by turning it off and
then on again.

Question: When the scanner is powered on, it makes noises

and won’t stand ready.

Answer: There are two possibilities:

1) You forgot to remove the shipping retainer
from the scanner. If this is the case, please
remove the shipping retainer first.

2) The scanner is not placed on an even, flat
desktop surface. This may cause the scanner
to function improperly.

Question: The scanner is powered on, but the lamp does not

light on.

Answer: The possible causes are as follows:

1) The lamp is out of order. In this case,
contact your local dealer or distributor to
change the lamp. The average life time of the
lamp is about 50,000 hours.

2) The fuse on the main board of the scanner is
burned. You can check the main board of the
scanner. If the fuse is burned, replace it with a
new fuse that is 250V/2A .

6-2

3) If the fuse is burned again after the changing,
it means the invertor of the lamp is burned.
Call your local dealer or distributor to replace
the invertor.

Question: To get image from the scanner is no problem. But

when scanning, the scanner or the system will often
crash.

Answer: 1) Please check that the cable is firmly seated.

2) Only two SCSI terminators can be connected
to your SCSI daisy chain. One is at the end of
the SCSI device, the other already in your host
adapter. (Please see Section 2-2 for more
details.)

Question: Scanning, the scanner will often make noises, or it

scans back and forth.

Answer: Please select a lower speed from the TWAIN

user interface for low-speed PC.

Question: Why is it the scanned images always come out to

be too dark.

Answer: 1) Modify the Gamma setting to1.8 for your

monitor and, when printing, set the Gamma
setting to 2.2 for your printer.

2) Adjust the Brightness setting from the TWAIN
user interface to get a brighter image.

Question: The scanner works well otherwise but for the

line art, of which the lines seem to be much
thicker than those of the original.

Answer: Use the Brightness or Threshold setting to

control the line art image.
