What to do if Canon Scanner is not recognized?
If your Canon Scanner is not recognized by your computer, first ensure that the scanner is properly connected via a USB cable and that the scanner is turned on. Also, verify that you are using the USB cable supplied with the scanner. The computer’s USB interface may not support the scanner. If you're using a USB hub, try connecting the scanner directly to the computer instead.
What to do if Canon Scanner jams documents?
If documents jam or double-feed in your Canon Scanner, and the roller has been installed correctly, clean it if necessary. Proper scanning may not be possible when document pages stick together due to static electricity. Try manually feeding the scanner one page at a time.
Why Canon Scanner image doesn't appear after scanning?
If the scanned image does not appear on the application after scanning all placed documents with your Canon Scanner, and [Panel-Feeding] or [Automatic Feeding] is selected as the feeding method on the scanner driver's Detail Settings screen, a scanning operation will not continue after all of the documents are fed. You can finish the operation and send the scanned images to the application by pressing the Stop button on the operating panel.
Why can't Canon imageFORMULA R40 save multiple pages to one file?
If multiple pages of scanned images cannot be saved to a single file with your Canon Scanner, it may be due to the file format you are using. Depending on the file format, multiple scanned image pages cannot be saved as a single file with CaptureOnTouch.
Why Canon imageFORMULA R40 Scanner stops due to insufficient memory?
If memory becomes insufficient and scanning stops on your Canon Scanner, configure scanning conditions that use a large amount of the computer’s memory, scanning may stop because of insufficient memory. If an error message appears due to insufficient memory while scanning is in progress, exit the application, change the scanning conditions (e.g. reduce the resolution or page size) and then try scanning again. Also, the amount of memory used can be contained by turning off [Moire Reduction] and [Prevent Bleed Through/Remove Background] if they are set to on.
Why do white lines appear on Canon imageFORMULA R40 images?
If white lines or streaks appear in your scanned images from the Canon Scanner, try cleaning both sides of the scanner glass and the rollers. If there's a sticky substance like glue, carefully wipe it off the area where the lines appear. If cleaning doesn't solve the problem, the internal glass may be scratched.
Why is Canon imageFORMULA R40 Scanner skipping pages?
If pages are missing when scanning with your Canon Scanner, and the scanner driver’s [Scanning Side] setting is [Skip Blank Page], documents with very little black may be unintentionally skipped. To resolve this, decrease the likelihood of skipping blank pages, or set the [Scanning Side] to another mode, such as simplex or duplex. If pages are skipped due to document double feeding, see 'Problem 7 Documents jam (or double-feed).'
How to fix slanted images from Canon Scanner?
If your Canon Scanner is feeding documents askew, align the document guides to fit the documents as closely as possible, and load the documents so that they feed straightly. Open the document feed extension support and place the document. Enable [Automatically straightens skewed] in the scanner driver settings. 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.
How to stop double feeding on Canon Scanner?
If double-feeding occurs when scanning a document with multiple pages on your Canon Scanner, press the scanner's DFR button to continue the scan. You can also clear the [Detect by Ultrasonic] check box on the scanner driver settings screen.
Why Canon imageFORMULA R40 size detection is failing?
If the size detection and deskew functions fail on your Canon Scanner, and [Carrier sheet] is set to [Carrier sheet] in the [Feeding] tab of the scanner driver settings screen and you scan a document with black edges without inserting it in a carrier sheet, the size detection and deskew functions may fail. In such cases, disable the size detection and deskew functions, or set [Carrier sheet] to [None] in the [Feeding] tab.
