This conssomable "timely" is not announced by the original vendor of the printer, fax, scan (very large house of VPC for specialized professionals) nor clearly by the manufacturer. Moreover neither the seller nor the manufacturer sells the product, which was quite complicated to find. The end supplier found via AMAZON was perfect on all points. Without this imaging unit, your device no longer works even if you have a stock of all encres.Il Note the great weaknesses SAMSUNG site that supply and the possibility of finding it. When you exceed the 15,000 copies, do not store too much ink, or be able to find on an imaging unit.
