Note: You can enforce a security policy when the printer has EC3 (P3xx) firmware or below.
Affected printers
This issue has been seen on Lexmark CS / CXxxx, MS / MXxxx, and XM / M / Cxxxx printers, but other models not listed here could be affected.
Note: An x denotes any number within a given printer model series.
Explanation
This concern may occur after updating the printer firmware to EC4 or EC4.1. The firmware levels P43x – P47xmodify some security building blocks which in turn cause the policy enforcement failure.
Solution
Update the printer’s firmware to PE Release code P480 or higher. To obtain this version, please contact Lexmark Technical Support and reference this article ID. Support personnel can assist with the update procedure if necessary.
