IV. Epson 502 vs 522, What's the Difference

Let's take a closer look at the differences between Epson ink 502 and Epson ink 522 cartridges to help you learn more.

Epson 502 vs 522, What Is the Difference

1. Capacity Differences

The Epson 502 ink and Epson 522 ink cartridges are ultra high capacity ink bottles. The Epson 502 black ink cartridge prints approximately 7,500 pages. And the Epson 502 cyan/magenta/yellow cartridge has a page yield of 6,000 pages.

The Epson EcoTank ink 522 series, on the other hand, also maintains significant print page numbers, but the details differ. Its cyan/magenta/yellow ink cartridge produces about 7,500 pages, while the Epson 522 black ink cartridge yields 4,500 pages.

The above data are measured under specific industry standards and may contain errors. It is more accurate to focus on its ink capacity.

When printing the same thing, more ink capacity means more durability when printing: Epson 502 Black: 127 ml, C/M/Y: 70 ml each; Epson 522 Black: 65 ml, C/M/Y: 65 ml each. So, from this standpoint, both the Epson ink 502 and 522 inks offer excellent page yields, but 502 prints more pages than 522.

2. Print Quality Variations

The Epson 502 and 522 inks contain different ink formulas optimized for their respective printer series, resulting in slight differences in printing performance. However, these customized ink compositions ensure optimal print quality for their Epson printers. Every print maintains the sharpness, clarity, and vividness you expect from the first page to the last. Whether it's text or complex visuals, they produce clear, easy-to-read documents and vibrant, life-like images - for a variety of printing needs.

3. Price Comparison

For the 4-pack and black single pack, 502 Epson ink is more expensive than 522 Epson ink. For other color single packs, it's the opposite. The Epson 502 ink 4 pack is $58.95, with black ink cartridge priced at $19.99 and cyan/magenta/yellow inks priced at $12.99 each. Meanwhile, the Epson 522 ink 4 pack is $55.94, with black/cyan/magenta/yellow ink available for $13.99 each.
