General Notes (Scanner Driver)
ScanGear (scanner driver) is subject to the following restrictions. Keep these points in mind when using
it.

When using the NTFS file system, the TWAIN data source may not be invoked. This is because the
TWAIN module cannot be written to the winnt directory for security reasons. Contact the computer's
administrator for help.
Some computers (including laptops) connected to the machine may not resume correctly from
standby mode. In that case, restart the computer.
Do not connect two or more machine or multifunction printers with scanner function to the same
computer simultaneously. If multiple scanning devices are connected, you cannot scan from the
Operation Panel of the machine and also may experience errors while accessing the devices.
Software screens may not appear correctly on Windows Vista when font size is set to Larger scale. If
you want to display the screens with Larger scale fonts, change the theme in Appearance and
Personalization to Windows Classic as follows:
1. From the Start menu, select Control Panel.
2. Select Appearance and Personalization > Personalization > Theme.
The Theme Settings dialog box opens.
3. On the Theme tab of the Theme Settings dialog box, select Windows Classic under Theme.
4. Click OK.
Desktop changes to Windows Classic view.
Use the default display font size of the OS. Otherwise, software screens may not appear correctly.
Scanning may fail if the computer has resumed from sleep or stanby mode. In that case, follow

1. Turn off the machine.
2. Exit ScanGear (scanner driver), then disconnect the USB cable from the computer and reconnect

Do not enter the computer into sleep or hibernate state during scanning.
