Point to check
Did you connect the machine to your
computer before installing the printer
driver?
In Windows 2000/XP/Server 2003/Vista/Server 2008, if
the machine was connected to your computer with a
USB cable before the printer driver was installed from
the installer, check if information on the unsuccessful
installation remains in "Device Manager". (For
information on "Device Manager", see Help in
Windows.)
If the model name of the machine appears in "Other
devices" in "Device Manager", delete it, restart your
computer, and install the printer driver again.
4
Check the settings in "What action do
you want Windows to take?" ("File
signature verification" in Windows 2000).
If [Block] is selected, the printer driver cannot be installed.
Select [Warn] and install the printer driver again.
