Frequently Asked Questions

What does two complete refresh cycles in one box do to a production schedule?

It takes toner off the schedule almost entirely. This set holds eight cartridges across the full GPR-36 family — GPR-36BK black, GPR-36C cyan, GPR-36M magenta and GPR-36Y yellow — enough to refresh the machine completely and hold a full second cycle in reserve. Every cartridge is rated at up to 19,000 pages, so the box represents a long runway: swaps become a five-minute task done from the shelf, and reordering becomes a quarterly habit rather than a recurring interruption.

How much does the 8-pack save against two 4-colour sets?

Two of the family's 4-colour sets at $235.74 would total $471.48. This set is $453.00 — $18.48 saved, with the per-cartridge average down to about $56.63 against $58.94 in the 4-pack and $71.06 to $78.02 for the singles. The per-step saving in this family is modest; across eight cartridges it still adds up, and it arrives in one shipment instead of two.

Black and colours are matched at 19,000 pages here — why does that simplify stocking the big box?

Because no slot in the GPR-36 family is rated to outlast the others. In families where black is rated double the colours, a two-cycle reserve means colour turns over twice while black sits — a stocking puzzle. Here each of the GPR-36BK, GPR-36C, GPR-36M and GPR-36Y carries the same rating, so the two cycles in this box deplete in roughly the same rhythm, and a simple count by colour tells you where you stand.

How should eight cartridges be split between the machine side and the store room?

Keep one full cycle within reach of the machine — that is the working reserve, the cartridges that answer a warning the same day. The second cycle can sit in proper storage: sealed, flat, cool and out of sunlight. Date both cycles on arrival. Splitting them this way means the shelf by the machine never has to hold more than it needs, and the reserve never gets picked apart casually.

When is eight cartridges too much stock for one machine?

When the machine's colour and black volume is low enough that the second cycle would sit for a very long time, or when the machine itself is near replacement and its successor takes a different family. Toner stores well, but capital sitting in a cupboard is still capital. A site running one lightly used imageRUNNER will usually be better served by the 4-colour set and singles as needed.

If a cartridge from the second cycle is needed months from now and fails, what cover remains?

Each cartridge carries our 1-year warranty and 1-year free returns on its own merits, so rotate oldest-first, keep the boxes dated, and install the first cycle before touching the second. If a cartridge underperforms when installed, it goes back under the same terms as any other — the details are on our shipping and returns page, and support is available Monday to Friday, 9 AM to 5 PM CST.

This is the largest GPR-36 listing: eight compatible cartridges spanning the GPR-36BK black, GPR-36C cyan, GPR-36M magenta and GPR-36Y yellow, each rated at up to 19,000 pages — a full refresh for an imageRUNNER production or copy-room machine plus a complete second cycle in reserve. It ships from one of our four US warehouses in Illinois, Pennsylvania, Georgia or California, and every cartridge is covered by our 1-year warranty and 1-year free returns. The rest of the GPR-36 family is on the Canon toner page.

The GPR-36 fit list for this 8-cartridge set runs to the ImageRunner Advance C2030, ImageRunner Advance C2225, ImageRunner C2020, and ImageRunner Advance C2020. The rest of the GPR-36 family: the black cartridge (GPR-36BK), the yellow cartridge (GPR-36Y), the magenta cartridge (GPR-36M), the cyan cartridge (GPR-36C), and the GPR-36 4-cartridge set.
