Real, tested page yield
Straight from this cartridge's spec sheet.
Page yield is tested to ISO/IEC standards and may vary with content, print settings and environment.
What does 5% coverage mean?
Page yield is measured using the industry-standard 5% coverage page - not a fully inked page.
Most of the page stays blank at 5% coverage. A fully inked page uses far more ink, so you'd get far fewer pages from the same cartridge.
≈6 essays
from a 1,000-page cartridge (about 1,500 words each)
Text uses small type and lots of white space, so coverage is usually around 5%.≈300 photos
from a 1,000-page cartridge (standard 4×6 prints)
Photos use more colour and full-page coverage, so you'll get fewer than with text documents.
Won't damage your printer — guaranteed
We know some people worry a budget cartridge could harm their printer. Ours won't. In the unlikely event it does, we'll repair or replace your printer free of charge — no matter how old it is.
Your printer's warranty stays protected

Bottom line: there's zero risk in switching.
