System Is Not
Responding
If the scanner and/or host computer are not responding, perform the
following steps.
1. Power down the computer.
2. Power down the scanner.
3. Disconnect the IEEE-1394 (FireWire) cable from the IEEE-1394 port on
the back of the scanner.
4. Power up the computer.
5. Power up the scanner.
After you power up the scanner, the red and green indicator lights will
illuminate. After approximately one minute, both lights go out. When
the green indicator light comes back on, the scanner is ready to begin
scanning. However, the host computer may require a few more seconds
to detect the scanner.
6. Wait until the scanner light is green and no longer in the power-up mode.
7. Attach the IEEE-1394 cable to the IEEE-1394 port on the back of
the scanner.
8. Wait a few moments for the host computer’s operating system to recognize
the scanner.
The scanner is now ready to use.
Color Image Quality
Color image quality is highly subjective. Here are some things to consider
when scanning in color:
• The difference in the color outputs of scanners, printers, and monitors can
affect the perception of the scanned document.
• Computer displays and printer output can vary from model to model, and
from manufacturer to manufacturer. An image may be acceptable on one
display and unacceptable on another.
• Area lighting (fluorescent, natural, incandescent) can affect
color perception.
• The appearance of a colored area within an image can be perceived
differently, based on what surrounds it.
• The characteristics and condition of a document can have an impact on
color consistency.
• Color requirements may differ between environments (e.g., in a business
document environment, images are generally viewed on a monitor, whereas
in a “print on demand” environment, scanned images are printed).
To ensure that your scanner is delivering the best image:
• Clean the scanner. Contamination within the scanner degrades image
quality. (Refer to the Maintenance section for cleaning information.)
• Calibrate the scanner occasionally and make sure that the calibration target
is clean and unwrinkled.
