For details: Assigning an Application

When pressing a scanner button, an application program other than CanoScan Toolbox starts.
 
Cause: The application programs linked to the scanner buttons are changed.
Solution: Change the settings on CanoScan Toolbox. The application programs linked to the scanner buttons are managed by CanoScan Toolbox. You can link a different program to the scanner button by changing the CanoScan Toolbox settings.
  Assigning an Application

You can assign an application to open the scanned image for [OCR], [Photo-1], [Photo-2], and [PDF] in CanoScan Toolbox.

Method 1
To link a different program, click the [Set] button, select the program you wish to use, and click the [OK] button. The program file you choose must be an executable file.

<Windows>
Most application programs are contained within a folder labeled with its name or the software manufacturer's name inside the [Program Files] folder. The [.exe] file name extension is always appended to an executable file*. Double-click the file to confirm in advance that it starts the intended program.
*   If file name extensions are set not to display, open the Windows Explorer, select the [Tools] menu, followed by [Folder Options] and the [View] tab, and remove the check mark from the [Hide extensions for known file types] option.

<Macintosh>
Most application programs are contained within a folder labeled with its name or the software manufacturer's name inside the [Applications] folder. Since file extension names are not appended by Macintosh systems, you must find the executable file by searching for the file icon*. Click or double-click the icon to confirm in advance that it starts the intended program.
*   Please note that folders may also be represented by icons. Ensure that you select an executable file.

Method 2
You can link a program by dragging and dropping an executable file or its shortcut/alias from its folder on the desktop (or the [Start] menu for Windows) into the [External Program] box.

• Some applications do not work with CanoScan Toolbox.
• Some applications do not work if linked to its shortcut or alias.

To Delete a Link to an Application
To delete a link to a program, click the [Delete] button. In the confirmation dialog, click the [Yes] button ([OK] button for Macintosh).

• If no program is specified in [External Program], a message that asks you to link an application program will appear. Click the [OK] button and select an application program in the selection window.

Scan quality is poor (Image displayed on the monitor).
 
Cause 1: Scan resolution is low.
Solution: Increase the resolution.
For details: Resolution Settings
 
Cause 2: Error arising from application program specifications.
Solution: Some application program does not display the image clearly if the image is too small. Set the view mode to 100%.
 
Cause 3: Moiré appears.
Solution: Select [Magazine (Color)] for Select Source in the Simple Mode or turn on the [Descreen] option in the Advanced Mode of ScanGear. Turn off the [Unsharp Mask] function if the moiré effect is still too strong even when the Descreen option is on.
For details: Image Settings

• Moiré may also appear when a digital print photo is scanned.
 
Cause 4: Low display color depth.
Solution: Set your display settings on your computer to Medium (16 bit) or higher.
Windows: Right-click on the desktop and select [Properties]. Set the monitor color depth to 16-bit or higher.
Macintosh: In the System Preferences dialog, click the [Displays] icon and select the [Display] tab. Set the [Colors] list box to [Thousands] or a higher setting.
 
Cause 5: Dirty document glass or document cover.
Solution: Clean the document glass or the document cover of the scanner, taking special care not to press strongly on the document glass.
 
Cause 6: The scanner needs recalibration.
Solution: Recalibrate the scanner in the Advanced Mode of ScanGear.
For details: Image Settings
 
Cause 7: The status of the original is poor.
Solution: In Advanced Mode/Image Settings of ScanGear, correct the image using the Reduce Dust and Scratches, Fading Correction, and Grain Correction functions.
For details: Image Settings
 
Cause 8: The color may be different when scanning images that have uniformity of appearance (i.e., blue sky).
Solution: Set [Auto Tone] to [OFF], and then scan again.
For details: Image Settings
 
Cause 9: External light is causing partial overexposure of the image.
Solution: Cover the document with a thick dark cloth.
• If a print out of an image does not appear satisfactory or the same as what you see on the monitor, you may need to change the printer's settings, or the printer itself may have engaged in problems. See the printer's manual for details.

Scanned image is surrounded by extra white areas.
 
Cause: The area larger than the original is cropped.
Solution 1: Crop an appropriate portion of the image. Use [Auto Crop] in ScanGear to automatically set the scan area for your document. You can also manually specify the scan area, for example when there are white margins along the document.
For details: Cropping Frame in Preview Area
Solution 2:

Change the Paper Size setting in CanoScan Toolbox when you scan using the scanner buttons. Press a scanner button and click the [Cancel] button on the scanning progress dialog when it appears. A CanoScan Toolbox settings dialog will display. Reset the Paper Size setting. For non-standard sizes, select [Custom] and specify width and height values. Then click the [Scan] button to scan. See the Paper Size topic for details.
For details: CanoScan Toolbox

Trouble scanning with Multi Scan or Multi-Crop function.
 
Cause 1: Photos (items) positioned outside the supported area.
Solution: Check the position of the photos on the document glass.
For details on Multi Scan: Multi Scan Functions
For details on Multi-Crop: Advanced Mode Functions
 
Cause 2: Error arising from application program specifications.
Solution: Some application programs do not support multiple image scanning. Scan each item individually without using the Multi Scan or Multi-Crop function.
 
Cause 3: Dirty document glass or document glass cover.
Solution: Clean the document glass or the document cover of the scanner, taking special care not to press strongly on the document glass.

Slow scanning speed.
 
Cause 1: Resolution is set higher than necessary.
Solution: To view the image on a monitor, set the Output resolution to 150 dpi. To print, set the Output resolution to a value such as 300 dpi.
For details on resolution: Determining Resolution Settings
 
Cause 2: Image settings (i.e., fading and grain correction) are applied in ScanGear.
Solution: Turn these settings off.
For details: Image Settings

"There is not enough memory." message is displayed.
 
Cause 1: There is not enough memory to continue scanning.
Solution: Quit other applications and try again.
 
Cause 2: Resolution set too high or output size too large.
Solution: Reduce the resolution and/or output size and try again.

Computer stops operating during scanning.
 
Cause 1: Output resolution set too high.
Solution: Reboot the computer, lower the ScanGear's output resolution and rescan the document.
 
Cause 2: Insufficient hard disk space.
Solution 1: Error message may appear when scanning oversized document with high resolution. Obtain sufficient free hard disk space and scan again.
For details: Installation is unsuccessful (Insufficient free hard disk space).
Solution 2: When the progress bar displays 0% and stops, click [Cancel] at the window, change the scanning area smaller or set the resolution lower, and then scan again.
Solution 3: Open ScanGear from within the application program, click the [Preferences] button in the Advanced Mode, and change the folder listed in the [Select Folder Where Temporary Files are Saved] category to one on a disk with sufficient free space.
 
Cause 3: Multiple devices connected to the USB port.
Solution: Disconnect all other devices but the scanner from the port.
