[Misc] Ineo+ 287 (Biz C287) , not enough toner

[pinspin]

The copier does not add toner Y and M during copying. After Drum Units (Y,M) replacement, it began to work correctly .But after performing Gradation copier stopped adding toner again. In manual mode toner is added, but not enough (by about 25%) . We replaced Main Board , Motor&Hoppers toner ,but ineffectually . Toner is original , firmware new , counter about 6000. We will be grateful for any suggestions .

What was complain by customer?
How do you know its not adding toners?
What T/C ratio is it showing for both Y and M in level history.

1. Colors become pale.
2. Toner bottles do not rotate.

M = 3.6 , Y = 4.2 and both are decreasing.

Quite confusing as you replaced boards and other mechanical parts before hand????

What are TCR level settings for all colors, should be 0 by default. Increase the Y M values by 1 and Do Manual Toner Add, see what happens. Just to check you can try inc. TCR values of Y M to 2 also for quick response.
