Troubleshooting Common Problems and Solutions This section provides recommended solutions to common problems. If you have a problem that is not solved by the following, contact your local authorized Canon dealer. Problem 1 Solutions Problem 2 Solutions Problem 3 Solutions The scanner will not turn on. (1) Confirm that the power switch is set correctly. (2) Confirm that the AC adapter is plugged firmly into a power outlet. (3) When the power switch is in the AUTO position, the scanner only turns on when the computer is on. The scanner is not recognized. (1) Confirm that the scanner is properly connected to the computer with a USB cable. (2) Confirm that the scanner is turned on. See the previous problem (1) if the scanner does not turn on. (3) The computer's USB interface may not support the scanner. The scanner cannot be guaranteed to work with all USB interfaces. (4) Confirm that the supplied USB cable is used to connect the scanner to the computer. The scanner cannot be guaranteed to work with all available USB cables. (5) If the scanner is connected to the computer via a USB hub, try removing the hub and connecting directly to the computer. Documents feed askew (scanned images are slanted). (1) Align the document guides to fit the documents as closely as possible, and load the documents so that they feed straightly. (2) Enable the [Deskew] scanner driver setting. (3) If many pages have been scanned since roller cleaning, clean the rollers. If documents still feed askew, roller replacement or other maintenance may be needed. See "Replacing Consumables" on p. 26 for roller replacement procedures. Problem 4 Solutions Problem 5 Solutions Problem 6 Solutions Problem 7 Solutions Both sides are not scanned even when the Duplex scanner driver setting is enabled. Before executing a CaptureOnTouch job, ensure that the registered job settings are appropriate for the intended scanning. If [Simplex] is selected on the [Scanner Setting] tab of the [Job Register] dialog box, scanning will always be single-sided (simplex). To perform duplex scanning, either change the job setting or create another job for duplex scanning. If white lines or streaks appear in scanned images. Clean both sides of the scanner glass, and the rollers (both rubber and metal). If a sticky substance such as glue or correction fluid is found, carefully wipe with just enough pressure to clean the area where the lines appear. If the problem cannot be solved by cleaning, the internal glass may be scratched. Contact your local authorized Canon dealer. Pages are missing. When the scanner driver's [Scanning Side] setting is [Skip Blank Page], documents with very little black may be unintentionally skipped. Select another scan mode setting such as [Simplex] or [Duplex], or decrease the [Ratio of black pixels]. If pages are skipped due to the document double feeding, see "Problem 7 Documents jam (or double-feed)". Documents jam (or double-feed). (1) Confirm that the roller is installed in the scanner according to the Setup Guide page insert. The roller is not installed in the scanner when shipped, and proper feeding is not possible until it is installed. If the roller has been installed correctly, clean it if necessary. (2) Proper scanning may not be possible when document pages stick together due to static electricity. Fan the documents before you load them. (3) Set the feed selection lever to (Bypass), and manually feed the scanner one page at a time. 23
