The ink isn't that old I'm using Ricoh Priport Ink HQ 90
I go through it pretty quick doing 11x17 newsletters

How old is your ink?

This is happening with both of my drums, make new master prints are nice and dark after initial proofs, after about 75 to 100 sheets I begin to get uneven prints.
These are the steps I have taken so far, adjusted ink detection pulse to 6.0 on both drums, adjusted the thermal head voltage to 16.40, changed the pressure cylinder setting to on to override the speed and temperature sensor, then I set the pressure to it's highest setting 6, also checked the ink pump rotation counter seems that the pump is rotating, count number changes. Anyone with additional suggestions would be greatly appreciated.
