The Epson WorkForce Pro WF-4830’s cartridge system is only alright. The black cartridge yields a disappointing amount of pages, meaning you have to replace it quite often. However, the color cartridge’s page yield is good and shouldn’t need changing as often, depending on how much you print in color. Although having three color cartridges means you can change the empty ones without needing to replace them all at once, the printer doesn’t let you print in color if any of them are empty. Likewise, you can’t print in color if the black cartridge is out of ink. On the upside, there are high-capacity versions that should last longer, although we didn’t test these. We couldn’t find any third-party ink.
