Preventing Information Leaks by Sending Data to a Wrong Destination

Restrict the connection of external media to avoid the data being removed.

Preventing Information Leaks from the Media Slot

/ Prevent unauthorized copying or printed paper stolen by embedding a pattern on the printed surface or restricting normal printing.

Preventing Data Leaks from Printed Sheets

Prevent the leak of information when the machine is stolen or disposed by encrypting data.

Encrypting Data to Prevent Data Leaks Caused by a Stolen or Disposed Machine

  • Before setting this machine's security features, the administrators must read the descriptions on security completely and thoroughly. Pay particular attention to the section entitled Registering Administrators Before Using the Machine.

  • Administrators must inform users regarding proper usage of the security functions.

  • If this machine is connected to a network, its environment must be protected by a firewall or similar security measure.

  • For protection of data during communication, apply the machine's communication security functions and connect it to devices that support security functions such as encrypted communication.

  • Administrators should regularly examine the machine's logs to check for irregular and unusual events.

Checking Firmware Validity

When the machine starts up, this function is used to check that the firmware is valid.

If an error occurs while a verification process is performed, a verification error is displayed on the control panel.

Note that this can also be checked on Web Image Monitor after the machine starts. If an error occurs in a verification process of Web Image Monitor, Web Image Monitor cannot be used. If this is the case, check the control panel.
