i would say your dev is over life or there is a blockage from toner hopper to your developer unit. Manually add toner and if the value changes then its probably the dev.

Ok, add toner to developer Unit?
if that is too high is missing toner ?

Y testing and report.

You can try to de-tone it, then reset it but the real problem is there is not enough developer left.

Yes, the developer unit did not have enough starter.
Y change the developer unit and the bizhub running normal, TCR ~7.4

Just to add you can save all the old image units inc black dev unit then if any unit has a print quality issue due to low dev you can easily top up the toner/dev mix from the old units works great (assuming the drum isnt worn)
