Frequently Asked Questions

What does the second cartridge in this pack really cost?

Less than the first. A single Canon GPR-40 black cartridge (GPR40BK) is $61.58; this 2 pack is $104.68, so the second cartridge effectively adds $43.10 — and bought separately, two singles would total $123.16, making the pack saving $18.48. Each cartridge in the pack works out to $52.34.

What does that do to the cost per page?

Across the pair's 32,000 pages, the running cost falls from about 0.38 cents per page on a single to roughly 0.33 cents. On a machine rated for this cartridge class, that difference repeats across every page the pair produces — it is a small number applied a very large number of times.

How much printing does the pack hold in reserve?

32,000 pages: 16,000 in the machine and 16,000 sealed on the shelf. At 3,000 pages a week, that is over ten weeks of output secured by one order — a comfortable buffer for an office that cannot afford a toner gap in a heavy period.

Should the second cartridge go straight in when the pack arrives?

No — it should stay sealed until the first cartridge is spent. Toner keeps best in its packaging, stored flat away from heat. When the changeover comes, the reserve cartridge is already on site, so the swap takes minutes and the machine is back in service the same morning.

What if the reserve cartridge turns out to be faulty when we finally open it?

Each cartridge carries its own 1-year warranty, and returns are free within the first year, so a problem found at opening is handled the same as one found on day one. The process is set out on our shipping and returns page.

Are these genuine Canon GPR-40 cartridges?

They are compatibles, manufactured to the Canon GPR-40 (GPR40BK) specification and sold under our own brand rather than Canon's. Fit and rated yield — 16,000 pages per cartridge — match the original; the lower pack price comes from the branding and the two-at-once purchase.
