Chapter 6 Practical Examples
■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.
✔Are the rollers dirty?
✔Are the 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.
If this does not solve the problem, consider the following possible problems and causes:
Problem | Cannot scan from the feeder. |
Cause | The scanning side setting for the ISIS/ |
| TWAIN driver is set to [Flatbed]. |
Solution | Set the scanning side to a setting other than |
| [Flatbed]. |
|
|
■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 | The application does not support multi- |
| page TIFF files. |
Solution | Open the files using an application that |
| supports |
| images as |
| CapturePerfect 3.0. |
|
|
Cause | The compression format used by |
| CapturePerfect 3.0 is not supported. |
Solution | 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 | The scanned image is too dark (or faint). |
Cause | The [Brightness] setting is not set to an |
| appropriate value. |
Solution | If the image is too dark, set a higher brightness |
| setting, or if the image is too faint, set a lower |
| brightness setting. |
