Contact Lexmark Technical Support, reference this article ID# SO7869, and request back-level LW50.##.P589 firmware for testing purposes. You may also inquire about any new EC6 versions of PE firmware that corrects this issue.
Explanation
This performance issue was addressed with a previous EC5 PE-release level of firmware. The schedule required for regression testing, and the time required for planning EC6 .P632/.P633, prevented the inclusion of this fix.
