TROUBLESHOOTING►GENERAL PROBLEMS THE SCANNED IMAGE IS CLIPPED Check Is the original scan size setting smaller than the actual original size?  Solution ■ Set the scan size to the actual original size. If you have intentionally set a smaller size than the actual original size, place the original considering the reference placement position for the selected scan size. For example, when scanning an A4 (8-1/2" x 11") original using a B5 (5-1/2" x 8-1/2") setting on the document glass, align the original using the document glass scale at the left edge to fit the area you wish to scan into the B5 (5-1/2" x 8-1/2") scanning area. THE QUALITY OF THE SCANNED IMAGE IS POOR Check Is the original printed matter such as a book or magazine? When scanning a color or grayscale original, is the color mode set to [Mono2]? Are Internet fax addresses included in the transmission? Is the resolution setting too low? Is the compression ratio too high?  Solution ■ To reduce the moire effect, take the following procedure: When the original is printed matter, vertical patterns (moire) may occur. Select [Others] → [Sharpness] in the Base Screen of normal mode and soften the edges of image to reduce the moire effect (only in "E-Mail", "FTP/Desktop", "Network Folder", and "Scan to External Memory Device"). It may also be possible to reduce the moire effect by changing the resolution setting or shifting the original (or changing its angle) slightly on the document glass. ■ Setting the color mode to [Mono2] replaces the colors in the original with either black or white. This is suitable for text-only originals; however, for originals that contain illustrations, it is best to use the [B/W Start] key with the color mode set to [Grayscale], or set the color mode of the [Color Start] key to [Full Color] or [Grayscale] and then scan. ■ If you wish to send an image scanned at high resolution to destinations for "E-Mail", "FTP/Desktop", and "Network Folder", send the image to scanner and Internet fax destinations separately. ■ A low resolution setting results in a coarser image. Increasing the resolution setting produces a smoother image. (The higher the resolution, the larger the file size.) ■ If the compression ratio is set to a high value when "Color Mode" transmission is set to full color or grayscale, noise may be noticeable and colors may appear dull. Set [File Format] → "Compression Ratio" to a lower value to reduce noise and dulling of color. (The lower the compression ratio, the larger the file size.) This is set in Normal Mode. 10-51
