Re: C450i eat toner

I found the C450i Toner(K) running out faster than usual.
I tested the Drum(K) DV(K), any advice for me?
I tested the upgraded F/W to AA2J0Y0-F000-G00-J9.
I have found an abnormal TCR(K) value, is there anything else I need to check?
please help me at

Re: C450i eat toner

I had a similar problem with a C250i, tried drum, dev, HV-board, and last try was "print head skew adj." from service-mode.
I planed to replace the laser but the adjustment seems to have fixed it.
If its the same problem as this machine, check if machine is doing color stabilization way to often from the management list, mine had more stabilizations then TC, while our demo-machine had 24 when the TC was about 500.

Check out temp/humidity sensor readings.
