■ Documents Do Not Feed Properly If a document does not feed properly, first confirm the following: ✔ Are pages sticking together because of static electricity or another cause? ✔ Are you attempting to scan a document with size, paper thickness or quality that is not supported by the scanner? (See "Documents" on p. 3-3.) ✔ Are the feed rollers dirty? ✔ Are the feed rollers worn out? IMPORTANT • Double feeding occurs when document pages stick together, and incompatible paper thickness or quality can cause paper jams. Check your documents carefully before loading. • Replacement rollers can be purchased as consumables. If performance is not improved after cleaning the rollers, contact your local Canon dealer or service representative to purchase a Roller Replacement Kit, and replace the rollers (pickup, feed and retard rollers). (See "Replacing the Transport Rollers" on p. 5-5.) If this does not solve the problem, consider the following possible problems and causes: Problem Cause Solution Documents do not feed. The Continuous Manual Feed Mode is enabled. Set the Continuous Manual Feed Mode to [OFF] from the User Mode. (See "Continuous Manual Feeding Mode Setting" on p. 3-12.) Chapter 6 Practical Examples ■ Saved Image Files Do Not Open If image files saved by CapturePerfect 3.0 cannot be opened by another application, first confirm the following: ✔ Does the application you are using support CapturePerfect 3.0 image file types (*.bmp, *.tif, *.jpg and *.pdf)? If this does not solve the problem, consider the following possible causes: Cause Solution The application does not support multipage TIFF files. Open the files using an application that supports multi-page TIFF files, or save the images as single-page TIFF files using CapturePerfect 3.0. Cause Solution The compression format used by CapturePerfect 3.0 is not supported. Open the image file with CapturePerfect 3.0, set the compression format to [None], and save it again. ■ Scanning Results Are Not as Expected If the scanned images do not appear as expected, one or more ISIS/TWAIN driver settings may be incorrect, or your application may not support certain scanner functions. Problem Cause Solution The scanned image is too dark (or faint). The [Brightness] setting is not set to an appropriate value. If the image is too dark, set a higher brightness setting, or if the image is too faint, set a lower brightness setting. 6-7
