Xpress C1810
The Xpress C1810 is the entry Samsung-engine color laser in the CLT-504S family — compact four-color printing for the small office. It takes CLT-K504S black plus C504S/M504S/Y504S colors. Even entry color printers feed four cartridges, so the compatible CLT-504S set pays for itself with the first full replacement. Our cartridges fit perfectly.

Frequently Asked Questions
Do I have to replace all four toner cartridges in the Xpress C1810 at the same time?
No. The Xpress C1810 is a single-function color laser printer that lays down toner in four separate CMYK channels, so each cartridge — CLT-K504S black, CLT-C504S cyan, CLT-M504S magenta and CLT-Y504S yellow — is tracked and replaced independently. Black almost always empties first on text documents, while the three color cartridges drain together on graphics and photos. Replace only what the printer flags; buy a full set only when several colors are low at once.
Why do color prints from my Xpress C1810 look washed out even though the cartridges are not empty?
Check that toner-save or draft mode is not stuck on in the driver, because the Xpress C1810 will keep printing pale pages long after you forget enabling it. If density is set normally, pull the weakest cartridge, rock it gently side to side to redistribute the toner, and reseat it — that often restores rich color for a while. When all four colors fade together, the transfer belt or another imaging part is the likelier culprit than any single CLT-504S cartridge.
My Xpress C1810 rejects a brand-new cartridge as unrecognized. What actually fixes this?
Power the Xpress C1810 down, remove the offending cartridge, and wipe its chip contacts with a dry lint-free cloth before pushing it back in until it seats with a firm click. Cartridges that sat in a hot delivery truck or cold warehouse can also throw chip errors, so let a new one rest at room temperature for an hour first. If a third-party cartridge still will not register, the printer firmware may simply be refusing that chip revision.
