IP Ports Table
The Lexmark Communication System (LCS) handles all traffic to and from the printer. The applications use TCP/IP to talk to the LCS, which may trigger some firewall software. The TCP port used for communication between applications varies by product.
| Protocol or Function | IP Port Number |
| Default Print | (TCP 9100) |
| HBN3 | (TCP 9100) |
| HBN3 Scan | (TCP 9100) |
| FTP – File Transfer Protocol | (TCP 21) |
| HTTP – Embedded Web Server (EWS) | (TCP 80, 8000) |
| mDNS (Bonjour) – Auto Configuration and Discovery | (UDP 5353) |
| SNMP V2c/V1 – Simple Network Messaging Protocol | (UDP 161) |
| SNMP V1 Traps | (UDP 162) partial support |
| HBN3 HID – Human Interface Device | (UDP 162) partial support |
NOTE: Telnet sessions using port 9000 are not supported (e.g., c:/telnet <printer's_IP_address> 9000). FTP is supported for flashing files such as firmware, or for testing network connectivity; however, it is not suggested as a path for testing print files.
