Appendix B: Troubleshooting...
16 The Color Correction button is grayed out and you cannot select it.
Solution: This button turns gray when the DCR or Dynamic Color Rendi-
tion files are missing from the Microtek\DCR directory. To fix this prob-
lem, run the calibrator program and calibrate your scanner, or reinstall the
ScanWizard so that the default profiles are copied onto your system. A new
set of profiles will then be generated.
17 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 #11.
18 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 3.0 does; others may not).
