Frequently Asked Questions

Why buy two of a cartridge that already lasts 24,600 pages?

Because the second cartridge is not about volume — it is about the day the first one dies in the middle of a job. Swapping in a shelf spare takes two minutes; waiting on a delivery takes days. With the 106R03584 rated at up to 24,600 pages per cartridge, this 2-pack puts 49,200 pages of cover in the building, and the spare sits there precisely so a deadline never depends on a courier.

What does each cartridge work out at in this pack, and what do I save?

The pack is $50.53 for two cartridges, which is $25.27 per cartridge. Bought one at a time at $34.51, two singles would come to $69.02, so the pack saves $18.49. Across the pair that works out to roughly 0.10 cents per page — the same extra-high-capacity 106R03584, just bought ahead instead of in a hurry.

The first cartridge has just run out — what is the reorder routine?

Fit the spare, then reorder the same day. That discipline is the whole point of the pack: the shelf spare buys you the delivery window, and replacing it immediately means the cupboard is never sitting empty when the next cartridge fades. Offices that wait until the spare is half-used before reordering eventually end up back at square one — one cartridge, no backup, and a job due Friday.

How should the second cartridge be stored while it waits its turn?

Leave it sealed in its box, lying flat in a cool, dry cupboard away from direct sunlight and radiators. Toner keeps well stored that way, and the seal keeps dust and moisture off the unit until fitting day. Only open it when the old cartridge actually comes out — an unsealed spare gathers dust and invites mix-ups with the empty one.

Are both cartridges in the box the same unit?

Yes — two identical 106R03584 extra-high-capacity black cartridges, each rated at up to 24,600 pages at standard 5% coverage. There is no standard-capacity cartridge mixed in and nothing to sort out at fitting time: whichever box you pick up second is the same cartridge as the first.

What happens if a cartridge in the pack turns out to be faulty?

Then it goes back: every cartridge carries a 1-year warranty, and returns stay free for a full year — the full terms sit on our shipping and returns page. Your order ships from one of our four warehouses — Illinois, Pennsylvania, Georgia or California — and the support desk is staffed Monday to Friday, 9 AM to 5 PM CST.
