Hello LOBO,
Yes, the % shows you the amount left on the consumable. I suggest calling into the support department 1-800-821-2797 to see if maybe the drum 46% had a defect.
I have an issue with print quality. It is faded and have looked at the drum cartridge kit which is at 46% , but when I swapped it with another machine which has a drum cartridge of 34% it prints OK. So are the %'s meaningful?
