Magenta decides whether faces look healthy or sunburnt and whether reds print red or orange. This is the Claria family's standard-tier magenta: our compatible T078320, Claria Hi-Definition dye ink.


Its shelf-mates complete the six: T078120 black, T078220 cyan, T078420 yellow, T078520 light cyan and T078620 light magenta. The high-capacity tier above them is the 77 series — this colour's sibling is T077320 — and the two tiers can be mixed position by position, as Epson's own printer guides describe; our shelf carries the 78 tier. And the family's yield rule applies here too: no official Epson yield table exists for these codes, so this page states no page count rather than borrowing a seller's figure.
Fits all seven verified models — Artisan 50, Stylus Photo R260, Stylus Photo R280, Stylus Photo R380, Stylus Photo RX580, Stylus Photo RX595, Stylus Photo RX680. It carries a new compatible chip; the recognition note in the questions below is worth reading. Lifetime warranty, free returns for the first year.

Frequently Asked Questions
What ink is inside?
Claria Hi-Definition dye ink — Epson's six-colour photographic dye system for this printer generation. Dye ink is what gives these Stylus Photo and Artisan models their smooth photo gradations; it is a photo ink, not a pigment document ink.
Can the printer run with one colour empty?
No. Epson's support answers for these models are explicit: the printer will not operate if any cartridge is expended or removed. That is why the six colours are sold as singles — one empty position is all it takes to stop the machine.
My prints have a green cast. Could magenta be the cause?
Yes — a low or under-delivering magenta lets cyan and yellow dominate, and prints drift green. Check levels first; if magenta is the expended position, replacing this single cartridge is the fix, not a full set.
How do I install it?
Have the new cartridge ready before you remove the old one — these printers should not sit with a slot empty. Remove only the yellow tape, do not touch the green chip, press the cartridge into its colour holder until it clicks, close the cover and let the printer charge the ink.
Does changing ink affect CD/DVD printing?
No — the R260, R280, R380 and the RX all-in-ones print to ink-jet printable discs with the same six cartridges; there is no separate disc ink. Use ink-jet printable media and let a printed disc dry before handling it.
How should I store a spare cartridge?
Sealed in its vacuum pack, upright, at room temperature and out of direct sunlight; open it only on install day. (A specific shelf-life figure is not published for this product; see Specifications.)
Is this a genuine Epson cartridge?
No — it is a Clever Supplies compatible cartridge built to the genuine cartridge's specification and code, labelled compatible on the box and on this page. It is not manufactured by Epson.
What warranty and returns cover this cartridge?
A lifetime warranty: a cartridge that fails to perform is replaced. Free returns run for the first year. (Returns note: the 1-year returns period is our standing compatible-product policy, applied to inkjet as an assumption pending Emrah's inkjet-specific confirmation.)
How many pages will I get from it?
Honest answer: Epson does not publish an official per-cartridge yield table for the 78/77 family — its fact sheet gives no yield figures — so we do not print a page number for this cartridge, here or in the specifications. Photo yield depends heavily on image coverage in any case. Third-party listings quote figures for these codes, but they are seller claims, not Epson ratings, and we will not present them as specifications.
Which printers does it fit?
All seven officially verified models for this family: Artisan 50, Stylus Photo R260, Stylus Photo R280, Stylus Photo R380, Stylus Photo RX580, Stylus Photo RX595, Stylus Photo RX680. The list comes from Epson America's own Claria 78/77 fact sheet (CPD-32251) and Epson's support documentation.
Can I mix 78 and 77 cartridges in the same printer?
Yes. Epson's own printer guides for this family state the two tiers can be combined by position — their example is a standard 78 magenta installed alongside a high-capacity 77 black. Every slot reads its own cartridge. Note that our shelf carries the 78 standard tier; 77 high-capacity cartridges are a separate tier (see the family note on this page).
Will this cartridge be recognised by my printer?
This cartridge carries a new compatible chip. Recognition ('cannot recognize') errors are a known failure mode in this cartridge class, so seat the cartridge firmly until it clicks and restart the printer before assuming a fault. These printers have been out of production for years, so new firmware locks are unlikely — the realistic risk is chip quality, and a cartridge that will not recognise is covered by our lifetime warranty. We do not claim recognition is guaranteed in every case.
