B-3Appendix B: Troubleshooting
5 When you scan an 8-1/2-inch wide image, the left or right side of the image is
cut off.
Solution: This may happen if you are using a ScanMaker III scanner, which
has a maximum scanning width of 8.3 inches. Therefore, a small margin on
each side which will be cut off when you scan.
6 While scanning images, the scanner carriage (lamp) keeps going back and forth
or idles, resulting in very long scan times.
Solution: This is called backtracking. Microtek scanners have a feature that
allows for recovery from image defects that result from the carriage
scanning and stopping during the scan. The carriage usually goes back and
reads part of the image once, then goes back a second time to patch the
images together and create a smooth picture. On some machines, due to
low amount of memory or a large virtual memory size, the software forces
the scanner to stop and start too many times, causing backtracking (which
may happen on almost every scan line). To resolve this, you can:
• Increase RAM in the computer by purchasing more memory.
• For Windows 3.1 x users: Reduce or turn off virtual memory in the
Windows 386 Enhanced module inside the Main group.
• If using the OmniPage software, turn off the Auto Intensity feature under
the Options menu.
7 Your scanned images do not have the same color as the original.
Solution: Generally, scanners, monitors, and printers all see and output
color differently. In order to come close to the original colors, you need to
calibrate all three devices. Microtek's DCR color correction system ensures
that your scanner captures colors accurately, but to have these colors output
correctly to a monitor or printer, you need a color management system
such as Kodak's Color Management Software. These third-party color
management systems ensure color integrity throughout the color produc-
tion process from input to output. Usually, all scanners scan a little darker
or lighter than the original (for instance, a scanner may scan red as ma-
genta). This is not a fault of the scanner but is a situation inherent to
calibration of the equipment.
8 Scanned images have vertical white lines from top to bottom.
Solution: The mirrors of your scanner may be dusty or dirty. To resolve
this, open the cover and spray some air on the bottom mirror which is
roughly 8-1/2" long and is directly below the carriage (but moves with the
carriage). Do not clean the mirrors with glass cleaners such as Windex or
with cloth. If you want to use a liquid, use alcohol and lens tissue paper
(other materials may scratch).
