Set the MP Navigator [Document Type] and [Document Size] to match
those of the originals being scanned. For more information, refer to the
Scan Guide.
Set the Setup CD-ROM and install the software.
Select this machine in [Select Source] or [Import] in your application
software.
Make sure that your application software supports TWAIN. You cannot
start ScanGear MP from within an application software that does not
support TWAIN.
Check the settings of the access point and modify the settings of machine
as same as those of the access point. For information on the access point
settings, refer to the access point manual.
For information on how to set a WEP/WPA/WPA2 key, refer to "How to set
a WEP/WPA/WPA2" of "Troubleshooting" in the Network Guide.
Make sure that the computer can communicate with the access point.
Adjust the installation positions and the antenna direction while
monitoring the radio status with Canon IJ Network Tool.
Relocate the machine and access point as closely together as is possible.
Communication between different rooms or floors is generally poor.
Adjust the installation locations of the devices.
There may be a device such as a microwave oven that is using the same
frequency bandwidth as the wireless station. Place the wireless LAN
devices as far away from the radio wave interference source as possible.
Complete the machine setup. If the MP driver is not installed, follow the
procedure described in the Setup Guide to install the MP driver.
On the access point, additionally register the IP address or MAC address
of the machine and the computer, or disable the MAC address filtering or
the IP address filtering.
