9 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.
10 The options billions of colors and 1000s of shades of gray are grayed out.
Solution: These two options are available only with the ScanMaker III. The
option billions of colors is a mode in which you scan 67.8 billion colors,
and this requires a 36-bit scanner like the ScanMaker III. The option 1000s
of shades of gray is 12-bit (equivalent to 4,096 shades of gray) and is also
available only through a 12-bit-per channel scanner like the ScanMaker III.
These options can be used only if your application supports them (Photo-
shop does; others may not).
11 This message appears: "Not enough disk space."
Solution: You may get this error message if you try to scan an image larger
than the space available in your hard disk. Keep in mind that when
scanning into Adobe Photoshop, you need hard disk space that's 2 to 2-1/2
times the file size of the image. In addition, Windows virtual memory takes
up a substantial amount of disk space to emulate memory or RAM,
resulting in reduced disk space for your program and scanned images.
Another situation in which this message may appear is when you use the
descreen function. With the descreen option selected (under the Filters tool
in the Settings window), you need a hard disk space that's 8 times that of
the image's file size. For example, to scan a 5-megabyte color image with
descreen, you need 40 megabytes (5 x 8) of available disk space. If you
turn off descreen, you will need a hard disk space that's 2.5 times that of
the image's file size (12.5 MB, or 2.5 x 8).
12 When you preview or scan, the scanner will not move, but an image appears in
the software as if the scanner was working.
Solution: This problem may be due to the scanner selection under the
Scanner pull-down menu in the Preview window. If you select ScanMaker
Demo, the program will go through all the motions of scanning an image,
but it will use a sample image file instead of the scanner as the source. To
fix this problem, select your scanner model from the Scanner menu. This
will change the source from the sample image file to the scanner. If no
scanner model appears in the Scanner menu, you may have a communica-
tion problem with your scanner. See troubleshooting tip #13.
