The original Kyocera DK-8720 drum, together with the toner, produces the printouts from the printer. The high capacity drum is very suitable for offices and does not need to be replaced often. This drum has a capacity of approximately 600,000 pages.
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.
