Roland Sign & Display vs Density Control

[cybernalin]

I do have problem with Cyan print head
i can't print 100% cyan with Sign & display profile it's printing faded cyan like 50%
But density control works fine
I Cleaned dampers and pump unit but i can't find issue related hardware
Test print is 100% Okay
Reinstalled software and still can't find the solution
Do you guys have any ideas about this issue

Mostly i used sign and display for prints
But now i can't use sign and display at all
when i'm using sign and display for portrait or something cyan is not printing at all
