Cool Toner 4-Pack CLT-K504S/C504S/Y504S/M503S Toner Cartridge Set

Four-colour laser toner set

This four-pack supplies black, cyan, magenta and yellow cartridges for Samsung colour laser printers. It fits models including the CLX-4195 series, CLP-415 series and Xpress SL-C1810W and SL-C1860FW. The set is intended for home offices or small workgroups that need full-colour output from a single purchase. Buyers with mono-only printers or machines that use separate high-capacity drums will not be served by this kit.

Consistent page yields across colours

Black cartridges are rated at 2500 pages while each colour cartridge is rated at 1800 pages under standard test conditions. Because all four units are installed together, colour balance remains stable over long print runs without the drift that can appear when cartridges are replaced individually. The ratings reflect continuous printing rather than short bursts, so daily workloads see predictable depletion rates. Users who regularly print heavy graphics should plan for earlier replacement than the rated figures suggest.

Low thermal impact and quiet operation

Laser toner produces minimal heat during normal printing cycles and the cartridges add no moving parts, so system noise stays at the printer's baseline level. Power draw is limited to the printer's own fuser and engine, with no additional consumption from the supply items. The sealed design prevents toner dust escape, keeping internal components clean during extended use. Environments that require silent operation or strict temperature control will not notice any change from these cartridges.
