Frequently Asked Questions

What exactly arrives when I order this 2-pack?

Two individually sealed TK6307 black cartridges in one shipment, each rated at 35,000 pages and each priced within the $216.27 pack total. The working pattern most buyers follow: one cartridge goes into the machine today, the second stays boxed on the shelf as the standing spare.

How should the spare cartridge be stored while it waits?

Keep it in its sealed packaging, flat, in a cool dry cupboard away from radiators and direct sun. Stored that way, a toner cartridge waits patiently for many months without the powder inside degrading, so there is no race to use the second unit.

Can the two cartridges be split between two different machines?

Certainly. They are two complete, independent units, so one can serve a TASKalfa 3501i on one floor while its twin runs in a TASKalfa 4500i elsewhere. Nothing about the pack ties the pair to a single device.

Why keep a spare for a cartridge that already lasts 35,000 pages?

Because big shared machines rarely run dry at a convenient moment. With the second TK6307 already on site, a change takes minutes instead of becoming an urgent order plus a delivery wait, and work on the device never queues up behind an empty toner warning.

If one cartridge from the pair misbehaves, what happens to the other?

Nothing — coverage is handled per unit, not per pack. A faulty cartridge is dealt with on its own under the 1-year warranty and 1-year free returns, while the healthy twin stays in service and your printing continues.

How is the pack shipped to us?

Both cartridges travel together from whichever of our warehouses — IL, PA, GA or CA — is closest to your address. Transit expectations and the returns process are set out on our shipping and returns page; support answers Monday through Friday, 9 AM to 5 PM CST.

Should the second cartridge go in at the low-toner warning, or only when printing stops?

Fit it at the warning if the next job matters. The low-toner warning is the machine telling you the end is near, and with the second TK6307 already on the shelf there is no delivery wait standing between the warning and the swap — a couple of minutes and the printer is back. For routine internal drafts you can run a little longer, but for anything client-facing it is better to change at the warning than to have the printer stop halfway through the job.

Which of the two cartridges should go in first?

Either one — the two TK6307 units in this pack are identical, each rated at 35,000 pages, so there is no better or worse choice. The tidy habit is first in, first out: fit the cartridge that arrived first and keep the second sealed on the shelf as the standing spare. That way the spare is always the freshest unit, and the shelf never holds a forgotten cartridge at the back while newer stock cycles through.

What if both of our machines call for a cartridge in the same week?

The pair splits. Each unit is a complete, independent TK6307, and because the TASKalfa 3501i, 4500i and 5500i all take the same cartridge as the 3500i, one unit can go into each machine with nothing to adapt. That is the quiet advantage of a shared shelf: two machines emptying in the same week is a pair of two-minute swaps, not two rush orders, and neither machine waits on a delivery.

The spare has sat sealed for months — anything to do before fitting it?

Check the seal and the code on the carton first: it should read TK6307, confirming the spare is the cartridge your machine takes. Then give the cartridge a few gentle side-to-side rocks to level the toner that has settled during storage, slide it in until it seats, and run a test page to confirm full density. If output stays faint after a proper reseat, contact us Monday through Friday, 9 AM to 5 PM CST — each unit carries its own 1-year warranty with 1-year free returns.
