❙Use the Brightness and Contrast, Hue and Saturation, or Tone Adjustment settings in your PhotoPlus software. Exact reproduction of colors is very difficult, but you can experiment to get as close as possible. See Chapter 4 for instructions.

Your scanned image looks “posterized,” with obvious steps between colors rather than blends, or it displays poor image quality on the screen.

❙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.

Your images don’t look as good printed out as they do
on the screen.

❙You may need to upgrade your printer. An EPSON color ink jet printer, for example, provides excellent image quality at an affordable price.

Your scanned image looks distorted or doesn’t havethe quality you expect.

❙To prevent electrical interference, plug the AC adapter into a surge protector.

❙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.
