Introduction

These days, by connecting your printers to the network, you can enjoy various useful functions including printing via the network.
Introduced below are the points to protect your printers from unauthorized access when you use them in the network environment.
Points to protect your printers against unauthorized access:

1. Use a private IP address.
2. Use a firewall or Wi-Fi router to limit communication.
3. Set the password to your printer.
4. Note: Precautions when Using Remote UI

The setting procedures or illustrations given in this document are examples, and they may differ from the ones of your printer. For specific details, refer to the Instruction Manual of your printer.

Using Private IP Address

An IP address is a number that is assigned to each device on the network. An IP address that is used to connect to the Internet is called “global IP address,” while an IP address within a local area network (LAN) is called “private IP address.” If a printer uses a global IP address, it can be accessed by the general public, which will increase risk of information leakage by unauthorized access from outside. If a printer uses a private IP address, then it can only be accessed by users on the same local area network (LAN) as the printer is connected to. In general, Canon recommends that you use a private IP address for your printer. An IP address within the ranges listed below is a private IP address. Check if your printer’s IP address is a private one. Range of the private IP address:
10.0.0.0 to 10.255.255.255
172.16.0.0 to 172.31.255.255
192.168.0.0 to 192.168.255.255

MEMO
Even if your printer uses a global IP address, you can reduce risk of unauthorized access by blocking access from outside using the firewall, etc.

How to check your printer’s IP address (Example)

Note: For specific procedures for checking the IP address, refer to the Instruction Manual of your printer.

Using a Firewall or Wi-Fi Router to Limit Communication

Firewall is a system to protect against unauthorized access from outside and to prevent network attacks or hacking. By restricting communication with a certain external IP address, you can block suspicious access from outside. Home-use Wi-Fi routers have similar functions. Be cautious when you change their settings.

Setting the Password to Your Printer

By utilizing the password functionality, you can protect various information of your printer and significantly reduce risk of information leakage in case of malicious access to the printer. Note:

• If a default password has been set, change it.
• No password is set by default depending on the printer model. Set the password.
• Some printer models do not have the password functionality.
• For specific procedures for setting the password, refer to the Instruction Manual of the printer.

MEMO
Printers have the password functionality for printer protection. What is important for your security is the proper use of the password. Keep the following in your mind in using the password: Always set the password. Change the password periodically. Avoid using an easy-to-guess password. DO NOT tell the password to others.

Screen Examples

Remote UI
The screen to set the password you will see at login to the Remote UI:

MEMO
Remote UI (User Interface) is the software that lets you access to the printer from a web browser in hand. You can check and change various printer settings using Remote UI without coming to the printer. When you enter the printer IP address or host name in the web browser, you will see the portal page of Remote UI.
Note: For details of Remote UI operation, refer to the Instruction Manual of the printer.

Precautions when Using Remote UI
Do not access other websites when the browser is accessing the Remote UI of your printer.
Do not forget to close the web browser if you step away from the computer or after you finish changing settings.
