You have not answered questions about other parts volume. Replace K PCDU after clearing PM counter, see how it goes.

Did you replace PCU?

What do I do???

with your fingers, turn the gear of the black development group a few turns, back and forth a dozen times, to clean a doctor blade, and try, then try to reverse the pcu of black (pcu only), with that of yellow, and see what happens, if you don't solve.. at this point you just have to do as I do, go to the customer with (ITB unit, pcu, dev unit, and possibly another power pack, all of another machine

On my earlier post, I mentioned I cleaned the optics very well.
