The original Konica Minolta DR-618 (ACV80RD) black drum, together with the toner, ensures the build up of detailed prints. With a capacity of approximately 240,000 pages, the drum does not need to be replaced often.
Note: this is a drum, not a toner!
A drum is not a substitute for an empty toner. Only order a drum if your laser printer indicates that the drum needs to be replaced.
