Workaround Method

In order for customers to use the product safely and securely, please install and configure it according to the security guidebook here.

  • Installation according to the security guidebook
     
    1. Connecting to the internet

      The product should not be directly connected to the Internet and should be installed in a network protected by a firewall.

      In that case, please set a private IP address and operate.
       
    2. Administrator Password

      Set an administrator password for each product.

      The administrator password should be a complex string that is difficult for others to guess, such as mixing not only English characters but also symbols and numbers to make it 8 characters or more.
       
  • Stronger workaround - Block HTTP (TCP/80 port) access to the product

    1. Blocked by product

      For the following products, you can block HTTP access (TCP/80 port) in Web Config*.
       
      • Commercial and Industrial Printers

        SureColor T5200 Series, SureColor T7200 Series, and SureColor T5200D Series
         
    2. Shut off network equipment in the installation environment

      After configuring the product, block HTTP access (TCP/80 port) to the product with a network device (router or switch).

      Open the port only when you need to update the application settings or firmware.

*Due to blockage, the functions in Web Config may not be available.
