:-D
It is possible for the D Max to drop off on an individual color at the 95% range. Density and VFF and V00 readings will be normal.

Version 36 DC Con allows the technician to boost the D Max of an individual color.
In service mode level 2 select COPIER>OPTION>BODY>DMX-OF-X (where X is the color of the curve that drops off at about 95%, Y,M,C or K).
Change the setting from 0 to 1. You must power cycle the machine then run Autogradation and Calibration. Check the curves again. If you need more improvement, you can change the setting to + 2 or +3. You must power cycle, perform Autogradation and Calibration each time.
**Knowledge is time consuming, exhausting and costly for a trained Tech.**
I have changed DMX-OF-C to 1 then 2 then 3. Power cycled then did Full Auto Graduation and then calibration. I have no change in the calibration curve.
I found it. I had TNR-DOWN set to 1, changed to 0 and power cycle, auto graduation, calibration. Level are now low, but within the .15 to be in spec. Thanks.
