Please advise if you know what is the usual schedule for service of C6501, if it is contracted with KM. Preciselly, does it mean that parts (drums, developers...) are to be changed when their life is over 100%, no matter what number of cliks counter list shows, or they should be replaced after 200.000 clicks, although their life will be over 130% at that time, as I was told by KM (counter list is attached). If so, what is the purpose of percentages?
