If machine is consuming more toner then there should be more toner in DV tank, but when i look in level history, Toner ratio /toner level is 6.3 which is normal according to service manual.
I think print is more contrast because of change of Developer type. Its the developer of 367 and i am using it in 458.
Ooo ok now i get it. So say the dev you add has a TC ratio of 10% and you initialize it it will read and determine that it is 6.5%. The factory premix is at 6.5 so the machine will calibrate against that. So machine read 6.5% but in reality its 10%. You could use more toner my apologies.
Whatever
