You can install a CA certificate into your printer by either one of the following methods.

> Using EWS (Embeded Web Server)
> Using the Printer Setting Tool (Communication Settings)

Installing a CA certificate using EWS (Embedded Web Server)

1. Make sure the printer and your computer are connected via Wi-Fi®.
2. Start your web browser.
3. Type "https://machine's IP address" in the browser's address bar (where "machine's IP address" is the machine's IP address).
      E.g. https://192.168.1.2
4. If required, type the password in the Login field, and then click Login.

   The default password to manage this printer’s settings is located on the back of the machine and marked "Pwd".

   For more information, see [User's Guide] on the [Manuals] page.

5. Go to the navigation menu, and then click Network > Security > CA Certificate.
   
6. Click Import CA Certificate.
