I just replaced my black cartridge and my Aficio 41000 still says replace blank pcu - why?

The life counter of the black pcu has run out. It had nothing to do with replacing the toner. The replace pcu message comes on at around 50k on this model I think.

Resetting the photoconductor unit

After replacing the PCU, you can clear the counter by going to Clear mode, 107, push and hold Clear/stop. Screen should change. Push Copier, 7804 should clear drum counter.
