Frequently Asked Questions

• Why does this printer family carry two different black cartridges?

  Because the two blacks do different jobs. This dye black is the photo black — it lays down the deep, glossy blacks you see on photo paper. Everyday text on plain paper is printed from the separate pigment black tank instead. Both tanks live in the printer side by side, and each one is swapped out on its own schedule as it empties.

• Will ink levels still show on screen with this cartridge installed?

  Yes. The cartridge carries a new compatible chip that reports its ink level back to the printer, so the usual low-ink warnings keep working. It is a purpose-built compatible cartridge — not a refilled original shell fitted with a reset chip.

• Where does the XXL sit in the CLI-281 range?

  At the top. The XXL is the largest fill Canon makes for this family: in Canon's summary figures the standard tier is rated 200/250 pages, the XL 400/500 and the XXL 600/800. You pay more for the cartridge itself, but it works out the cheapest of the three per page printed.

• What page count should I expect from this black cartridge?

  Canon rates the XXL black at up to 6,360 pages in its published summary figures. Those ratings come from standard test pages at roughly 5% coverage, so treat the number as a benchmark rather than a promise: what you actually get follows what you print, and dense photos consume far more ink than plain text pages.

• Which PIXMA models use this black cartridge?

  It goes into the Canon PIXMA TR7520, Canon PIXMA TR8520, Canon PIXMA TR8620, Canon PIXMA TR8620a and 12 more printers. The full verified list sits in the Compatible Printers section of this page — confirm your model there before you order.

• Can this tank run alongside genuine Canon tanks?

  It can. The printer reads every slot independently, so this compatible black prints normally next to genuine Canon cartridges — and the reverse works too. There is no need to change the whole set at once; you can move over one color at a time.

• A message appeared right after I installed it — what now?

  Accept the on-screen message first, then take the cartridge out and reseat it until it clicks into place, and restart the printer. If the message comes back, wipe the gold chip contacts with a dry, lint-free cloth and put the cartridge in again.

• Is this an original Canon cartridge?

  No. This is a Clever Supplies compatible cartridge, built to the CLI-281XXL specification and covered by our lifetime warranty. Canon did not manufacture it; the Canon name is used only to identify the printers the cartridge fits.

• What happens if the cartridge leaks or the printer refuses to recognize it?

  Stop printing and contact us rather than pushing on with a faulty cartridge. Our lifetime warranty covers recognition failures, leaks and print-quality defects — we will replace the cartridge or refund you, and returns are free during the first year.
