Problem The CRT display image is not what you expected. The scanned image does not look the same as the original image. A line of dots is always missing on the scanned image. When using halftoning mode A, textured dots appear on particular areas of an image. Solution Problems and Solutions Try different settings and combinations of the scanner functions. (See Chapter 2.) Check that your software is correctly installed. Check the capability of your software and computer. (See your software and computer manuals.) If you are importing an image file into your application software, check that the file format is acceptable for your software. Also check that the settings on your software and your image match. (See your software manual.) If this happens on your printed image only, it is probable that your printer or its print head is malfunctioning. (See your printer manual.) If this happens both on your screen and printout, the scanner's sensor may be malfunctioning. Consult your dealer. The scanner is working correctly. This effect appears on areas of consistent color or luminosity because the scanner tries to simulate tones from such input. To decrease this effect, use halftoning mode B. (See Chapter 2.)
