Encrypting Communication (IPsec)
You can configure the settings in this section to encrypt and prevent tampering with
communication between the computer (client) and printer at the network layer level.
The IKE protocol supported by this printer is “IKEv1”. The communication mode supported by
this printer is “Transport Mode”. It does not support “Tunnel Mode”. Printer response may slow
down while IPsec is enabled, depending on network communication conditions.
Note: IPsec does not operate with the mail send function or SNMP Trap function.
