Slow Scanning Speed
The following problems might cause the scanning speed to be slow.
×
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?
IMPORTANT
•
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.
•
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.
•
When scanning continues, make sure that the last document scanned was
scanned correctly.
