The Epson XP-4100 has a poor inkjet cartridge system. It has multiple color cartridges, which is good since you don’t have to replace colors you don’t use as often. However, the page yield is quite bad, and the printer will stop printing entirely if even just one color cartridge runs out. The black page yield is especially terrible, so you’ll likely need to change the black cartridge fairly often. On the upside, there are high-yield cartridges available that last longer.
This printer will accept third-party cartridges, but they could void its warranty.
