The Toshiba drum OD-FC556 is indispensable in the printing process. This part ensures that the printout can be built up correctly. To do this, the drum works together with the toner in your laser printer. The drum has a very long life and will last approximately 520,000 pages.
Note: this is not a toner, but a drum!
A drum is not a substitute for empty toner. Only order a drum if your laser printer indicates that the drum needs to be replaced.
