Appendix B: Troubleshooting...
12 The Photoshop File-Acquire option is grayed out, and you cannot select the
option for your Microtek scanner.
Solution: You need to reinstall Photoshop.
13 Color images are washed out with little detail in the light or highlight areas.
Solution: Sometimes on certain images that are light, enabling the Color
Correction option or the Auto button (both in the Settings window) might
make the images very light and thus cause certain areas to wash out. To
resolve this, you may want to turn off these options.
Also, if you are scanning very light highlight areas and they're coming out
white, try reducing the exposure control (through the Brightness, Contrast
and Exposure tool) to a negative number.
14 Color images seem to have a pattern on them when scanned.
Solution: Check the following:
• Make sure that your display option in your Windows setup is set to 16.7
million colors.
• If you scan an image that came from a magazine or brochure, you will
get an artifact on the image called a moiré. Moiré patterns show up when
you scan an image that has been printed already. To reduce the patterns,
select the More Options tool in the Settings window, and then select the
Descreen filter. In the Descreen filter are options for newspaper, maga-
zine, and art magazine. For more details, refer to the Reference section
in the manual.
