When scanning continues, make sure that the last document scanned was scanned correctly.
If documents are not scanned normally even if the scanner setup is OK, a probable cause is that the scanner driver or application software is not running correctly. Re-install the scanner driver or application software.

⋅Scanning Is Not Performed

Check the following if the scanner does not scan an image even though the scanning operation is performed:

•Has the scanner been properly recognized by the computer?

•Has the scanner driver been installed?

•Has the application software been installed correctly? Has the application software been set up correctly?

•Is there a problem in the PC system?

•

• When system errors result in the scanner not functioning at all, turn OFF the scanner and wait at least ten seconds before turning it ON again. If the error

• continues to occur, restart the computer.

⋅Documents Do Not Feed Properly

The following are possible causes of a document failing to feed properly. Check each possible cause.

(See "Feeding in the Page Separation Mode," on p. 21.)
