The scanner driver is subject to the following restrictions. Keep these points in mind when
using the scanner driver.
Scanner Driver Restrictions
• If the computer is shared among multiple users or when you have logged out and back
on, a message indicating that the scanner driver is in use may appear. In that case,
disconnect the USB cable from the computer, then reconnect it.
• Scanning may fail if the computer has resumed from sleep state with the scanner driver
active. In that case, follow these steps and scan again.
1. Turn off the machine.
2. Exit the scanner driver, then disconnect the USB cable from the computer and
reconnect it.
3. Turn on the machine.
• Do not connect two or more scanner or multifunction printers with scanner function to
the same computer simultaneously. If multiple scanning devices are connected, you
may experience errors while accessing the devices.
• When using a network compatible model by connecting to a network, the machine
cannot be accessed from multiple computers at the same time.
• When using a network compatible model by connecting to a network, scanning takes
longer than usual.
• Make sure that you have adequate disk space available when scanning large images at
high resolutions. For example, at least 300 MB of free space is required to scan an A4
