C451/ineo 451+ image units (urgent)

[Zilviux]

Hi in my Bizhub c451 end life of Image units. But how i think it's only counters coz quality still good was.
So my quastion is the way to by pass trought in service mode and keep working? Or only solution is to reset chip in image unit?

enter tech rep mode press stop,0,C set image unit life to no stop and exit out. You will still get a warning message about the IU life but the machine will still function.
