1.Due to the different structure of both printer and ink cartridge, the different color & the different technology(ex, Gloria-dye based, or EverBrite-pigment based), different brands (ex Canon, HP, or Brother) are using different inks.


2. Universal Refill kits are using universal ink, for example, NR-T3111CMY’s ink model is UI-C309-D/CI-M09-B/Y07B, NI-052. They are different from the other compatible ink cartridges, such as CLI-8 (ink model: CI-M107-C), and NB LC103(ink model: BI-M322)
