Although the original Dell 593-BBSB is an exceptional product, our manufacturers have managed to produce an alternative that further reduces the running cost of your colour laser printer. Production costs are reduced by recycling many parts of the genuine product and replacing whatever cannot be reused with compatible Dell 6CVF8 parts.When fully assembled this remanufactured version of the Dell 593-BBSB is filled with a compatible black toner powder that offers the same page yield and comparable print quality.
