Use the Brightness and Contrast, Hue and
Saturation, or Tone Adjustment settings in your
PhotoPlus software. Exact reproduction of colors is

PhotoPlus scans pictures in 24-bit color (16.7 million
colors). Make sure your Windows display palette
(video driver) is set to high color or true color, or at
least 256 colors. See your Windows documentation
and the manuals for your computer or video card
for more information.
❙
Image quality also depends on the software you’re
using. If your application doesn’t support 24-bit
color, try converting your image to 8-bit color. See
pages 3-13 to 3-14 for information about converting
image types.
❙
Your images do not display the best quality if your
monitor or your computer’s video controller doesn’t
support 24-bit color. You may need to upgrade your
system to achieve the best on-screen resolution.

To prevent electrical interference, plug the AC

If you have an air conditioner, vacuum cleaner, or
other power-intensive appliance operating on the
same outlet as the scanner, it doesn’t scan correctly.
Move the scanner to another outlet and try again.
❙
Make sure you don’t touch the parallel connector
during the scanning process. Discharge yourself by
touching a metal object before you scan.
