Whilst the Samsung Xpress SL-C460FW and all other compatible printers are incredibly efficient machines, sadly they still produce a fractional amount of waste toner in every print and this toner has to go somewhere. In steps the genuine Samsung CLT-W406/SEE which prevents the waste toner from settling inside your printer, preventing the colours from reducing the quality of your prints. Maintenance items for laser printers tend to have a very long shelf life and the CLT-W406is no exception. You can expect to get an impressive 7,00 prints from the humbly priced CLTW406, which is a small price to pay for maintaining Samsung`s incredible print quality.
