Frequently Asked Questions

• How many pages does the CLI-8G print?

  It is rated at up to 280 pages — the cartridge supplier's rating — Canon published no official yield table for this family. Page counts are measured on standard test pages at around 5% coverage, so your own yield moves with what you print: dense photos use far more ink than text.

• Which printers take the CLI-8G?

  It fits Canon PIXMA Pro9000, Canon PIXMA Pro9000 Mark II. The complete verified list is in the Compatible Printers section on this page — check your model there before ordering.

• Which printers use the CLI-8G?

  Only Canon PIXMA Pro9000, Canon PIXMA Pro9000 Mark II have a Green slot. The other printers in this family do not use this tank.

• What does the green tank do?

  Green extends the color gamut into saturated greens that cyan and yellow cannot mix on their own.

• Does this cartridge have a chip?

  Yes — a new compatible chip that reports ink levels to the printer, so the low-ink warnings keep working. It is not a refilled original shell with a reset chip.

• Can I mix this cartridge with genuine Canon cartridges?

  Yes. Each slot is read independently, so a compatible tank beside genuine Canon tanks (or the other way round) prints normally — you can switch one color at a time.

• My printer shows a message after installing — what do I do?

  Acknowledge the on-screen message, reseat the cartridge until it clicks, and restart the printer. If the message persists, wipe the gold chip contacts with a dry lint-free cloth and reinstall.

• Is this a genuine Canon CLI-8G?

  No. It is a Clever Supplies compatible cartridge built to the CLI-8G specification and covered by our lifetime warranty. It is not manufactured by Canon; the Canon name appears only to identify the printers it fits.

• What if the cartridge leaks, is not recognized or prints badly?

  Stop and contact us — do not keep printing on a faulty cartridge. The lifetime warranty covers recognition failures, leaks and print-quality defects: we replace the cartridge or refund you, and returns are free for the first year.

• Why does the green tank seem to last forever in some printers and drain quickly in others?

  It comes down to what the printer is asked to print. The CLI-8G exists only in the PIXMA Pro9000 and Pro9000 Mark II, and it is a specialist tank: it lays down the saturated greens — foliage, grass, landscape work — that cyan and yellow cannot mix on their own. A photographer printing landscapes all week draws this tank down steadily, while someone printing portraits, documents or city scenes may barely touch it for months, because those subjects call on green only lightly. That uneven use is normal, and it is also why this tank's 280-page rating is a poor calendar guide: judge replacement by the printer's ink-level readings and by how your greens look — foliage turning dull or yellowish is the visible sign the CLI-8G is running down — rather than by how long the cartridge has been installed. Keeping a brief note of which tank you changed and when, over a few cycles, will show you your own pattern far better than any printed rating can.
