Chapter 3 Symptoms The scanned image is abnormal for certain documents. Problem Functions such as [Auto-detection], [Deskew], or [Border Removal] were used when scanning documents containing text or photos up to their edges. (The scanner cannot accurately process the edges of documents.) Solution Turn off functions such as [Auto-detection], [Deskew], or [Border Removal] when scanning documents containing text or photos up to their edges. (See "Software Settings," on p. 49.) Symptoms The scanned image is abnormal in some applications. Problem A function not supported by the application was used. Solution Some applications do not support functions such as auto-detection of the paper size. Scanning documents with an application such as this will result in an abnormal scanned image. Try scanning with auto-detection of the paper size set to "off." Adjusting the Scanner To adjust the scanner, set the supplied Adjustment Sheet (Shading Sheet) in the scanner. Orient the adjusting sheet in the direction indicated by the arrow when setting it in the scanner. After setting the Adjustment Sheet in the scanner, click the Windows [Start] button, and then click [Programs] (All Programs in the case of Windows XP) Æ [Canon Document Scanner], and then [DR-2050C & 2080C Adjustment Tool], or use the [Scanner Adjustment] function of the ISIS/ TWAIN driver. Follow the instructions on the dialog box that appears on the screen to adjust the scanner. Refer to Help for the ISIS/TWAIN driver for information about the ISIS/TWAIN driver [Scanner Adjustment]. Adjustment Sheet (Shading Sheet) CAUTION Before performing scanner adjustment, be sure to clean the scanning glass (see p. 59). Attempting to perform scanner adjustment while the scanning glass is dirty can cause vertical lines in the scanned image. Note that performing scanner adjustment will cause previous adjustment data to be deleted. Once deleted, adjustment data cannot be recovered. Appendices 77
