Hello Zhao (also known as zCanon),
Sorry, I mixed up the model number. However, the information is still the same with the exception of the web site location and drivers. Here's the updated information for the imageCLASS MF4350d.
1. Click HERE to go to the Drivers & Downloads page for your MF4350d.
2. The Drivers & Downloads page will open for the selected model.
Note: This page automatically detects your computer's operating system so that only the compatible drivers and software will be available for download.
3. Click on the SELECT button next to [Windows 32bit] imageCLASS MF4350d MFDrivers (UFR II / FAX / ScanGear) or [Windows 64bit] imageCLASS MF4350d MFDrivers (UFR II / FAX / ScanGear) to download the drivers.
4. After clicking on the SELECT button next to the file name, click on the DOWNLOAD button to save the file to your computer.
5. Once the download is complete, double-click the file from its download location to decompress them. A new folder will be created in the same folder. The new folder will have the same name as the compressed file. (When you select [RUN], it unpacks the setup folder.)
6. If the Setup Wizard doesn't start automatically, open your Downloads (or Documents) folder.
(1) You will see two icons with the name: MF4350MFDriversV270W32usEN or MF4350MFDriversV270W64usEN. Double-click on the yellow folder icon with this name.
(2) In the folder you will see two listings for Setup. Double-click on the Setup that has the type as 'Application'.
7. The Setup Wizard will open. Proceed through the on-screen steps.
8. Connect the USB cable and allow the installation to complete.
9. Once complete, return to the Drivers & Downloads web page and click on Software to view the section.
11. Click on the SELECT button next to [Windows 32bit & 64bit] Tool Box Ver.4.9.1.1.mf18.
12. After clicking on the SELECT button next to the file name, click on the DOWNLOAD button to save the file to your computer.
13. Once the download is complete, double-click the file from its download location to decompress them. A new folder will be created in the same folder. The new folder will have the same name as the compressed file.
14. In the new folder, double-click the decompressed Setup file to start installation.
Next, please follow these steps to set MF4350d as your default printer:
1. Open the Printers Folder:
* Right click Start ->Settings ->Devices ->Devices and Printers.
2. If there is more than one Canon printer icon shown, right-click on the printer driver you wish to use and Left-Click 'Set as Default Printer'.
3. If the printer icons are stacked, right click on the printer icon shown and hold the mouse on 'Set as Default Printer' until the full list of drivers appears. Left click on the UFR II printer driver to use.
4. When the printer has been set as the default printer, a check mark is displayed beside the printer icon.
