Pro Tip

Frequently Asked Questions
Can I mix standard 133 cartridges with high-yield 138 cartridges in the WorkForce 525?
Yes. The WorkForce 525 accepts any combination of 133 and 138 individual cartridges. You can run a high-yield 138 Black cartridge alongside standard 133 Cyan, Magenta, and Yellow cartridges without operational issues.
Why do individual colour cartridges deplete at different rates during black text printing?
Even when printing black text documents, Epson printhead technology periodically uses tiny amounts of colour ink to keep the micro-nozzles primed and prevent clogging. Heavy document users often find colour cartridges lower slightly over time even if photo printing is minimal.
What is the benefit of buying 138 high-yield cartridges over standard 133 cartridges?
High-yield 138 cartridges contain more usable ink inside the same cartridge shell size. They yield approximately 380 black pages compared to 230 pages from standard 133 black cartridges, offering lower cost per page and fewer cartridge swaps.
