Epson 102 EcoTank Cyan Ink Bottle (genuine, 70 ml)
By Seb Clark, Editor, UniDoc Solutions·Updated
One of the three 102 colour bottles — buy whichever tank is lowest.
Colour pages cost about 0.6p all-in across the three colour bottles.

Our take
Cyan, magenta (C13T03R340) and yellow (C13T03R440) are identical 70 ml bottles at the same price. Colour tanks drain at different rates depending on what you print, so buy singles as needed rather than a set. Each bottle is good for around 6,000 pages at ISO coverage.

Genuine vs compatible — which should you buy?
Genuine cartridges cost more per page but carry the maker's warranty, hit the quoted page yield reliably, and never trip firmware "unrecognised cartridge" blocks.
Compatible (third-party) cartridges are typically 40–70% cheaper. Quality is fine from reputable sellers, but yields are optimistic, colour accuracy varies, and some brands (HP with HP+ in particular) actively block them. For a mono laser printing text, compatibles are usually the sensible buy; for colour or warranty-critical kit, stay genuine.
