Problem Solution
When the scanner is powered up, the lamp
does not light.
• The lamp is dead. Contact your dealer to change the lamp. Lamp
life is about 15,000 hours.
• If the power light on the ADF is flashing, the power adapter is
malfunctioning or the main board has short-circuited. Contact your
dealer to replace the power adapter or main board.
The scanned image is too dark.
• Modify the Curves setting to 2.2 and 1.8 for your printer and
monitor, respectively.
• Use the Brightness setting to get a brighter image.
The scanned lines of Black and White images
seem much thicker than those of the original.
• Use the Brightness or Threshold setting to adjust Black and White
images.
The color image quality is not acceptable. Color image quality is highly subjective. Here are some things to
consider when scanning in color:
• The differing color gamuts of capture, display, and output devices
can affect color perception. Computer monitor displays and printer
output can vary from model to model and from manufacturer to
manufacturer. An image may be acceptable on one monitor 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.)
• Make sure that the ADF and the glass areas are clean.
