These ports include the following:

  • 9100 and 9400 used by MFP for basic communication over the network
  • 137, 138, 139 used by NetBIOS for names resolution
  • 445 used by the SMB protocol

IMPORTANT! If a WINS or DNS server is being used for host name resolution, the required NetBIOS ports may be closed or blocked.
