Blocked Ports and Processes Affecting MarkVision's Ability to Communicate over a Network

Overviewand Article Contents

This article describes the ports and protocols used by MarkVision™ Professional (MVP). Any network firewall blocking these ports between any MVP version server and a client/remote device will break basic functionality, such as discovery, policies, job accounting, etc.

Identify the failing communication path for MVP and consult or contact your firewall provider or manufacturer for additional troubleshooting assistance.

  1. MarkVision Client and Server Communication

Communication between clients and the MarkVision Server is based on Java RMI (Remote Method Invocation) technology. MVP uses randomly selected ports on the server to communicate to devices and MVP leaves the specifics of ports selection to the underlying java virtual machine. This facilitates its multi-threaded functionality.


NOTE: The initial binding for a client-server session occurs on the 9188 port on the server side. All successive calls are made through Ephemeral ports on either side.

Still Need Help?

Please contact Lexmark Technical Support if you need additional assistance.
NOTE: When calling for support, you will be asked for your machine/model type and Serial Number (SN).

Please call from near the printer in case the technician on the phone asks you to perform a task involving the printer.
