Frequently Asked Questions

The set is listed with four codes — 1T02LK0US0, 1T02LKCUS0, 1T02LKBUS0 and 1T02LKAUS0. What am I actually ordering?

One boxed set of four TK-8307 cartridges: black 1T02LK0US0 (TK-8307K), cyan 1T02LKCUS0 (TK-8307C), magenta 1T02LKBUS0 (TK-8307M) and yellow 1T02LKAUS0 (TK-8307Y). The four codes are simply the individual part numbers of the cartridges inside, so you can check each one against the label of the cartridge it will replace before you open anything. The complete set is $296.93.

How many cartridges of each color are in the box?

One of each. The set carries a single black, a single cyan, a single magenta and a single yellow cartridge — a full four-slot refresh in one carton, not multiples of one color.

Why is the black cartridge rated at 25,000 pages when the colors are rated at 15,000?

Because the ratings follow how the machine actually consumes toner. Most office output is black text, so the black cartridge is built and filled for 25,000 pages, while each color is rated at 15,000 pages. Both figures are the standard per-cartridge ratings for the TK-8307 family, measured the same way across all four.

Only one color has run out. Do I have to fit all four cartridges at once?

No. Fit the cartridge the machine is asking for and leave the other three sealed in the box. Each cartridge is individually wrapped, so the unopened ones keep their full shelf life in a drawer until their turn comes. On a TASKalfa 3050ci — and equally on the TASKalfa 3051ci or TASKalfa 3550ci — each color swaps independently through the front of the machine.

How should the unopened cartridges be stored?

Flat, in their sealed packaging, away from direct sunlight and heat vents. Kept that way, a cartridge from this set is ready to install months after the first one went in, with no loss of print quality.

If one cartridge from the set turns out to be faulty, what happens?

It is handled on its own — you do not send the whole set back. Every cartridge is covered by a 1-year warranty and 1-year free returns; the full terms are on our shipping & returns page. Orders ship from our warehouses in IL, PA, GA and CA, and support answers Monday–Friday, 9 AM–5 PM CST.

Which cartridge in the set will I replace first?

Almost always the black. Most office output is black text — letters, reports, invoices and forms — so the TK-8307K black does the heaviest work even though it starts from the biggest fill at 25,000 pages, while each color is rated at 15,000. Watch the black slot first: when it calls for a change, fit the black 1T02LK0US0 and leave the three colors sealed, because they will still have life left in them.

What should I check on the box when the four-color set arrives?

Open the carton and match all four codes against the list: black 1T02LK0US0 (TK-8307K), cyan 1T02LKCUS0 (TK-8307C), magenta 1T02LKBUS0 (TK-8307M) and yellow 1T02LKAUS0 (TK-8307Y), one of each. A minute of checking at delivery confirms the set is complete and catches a picking error while the shipment is fresh. Note any crushed packaging on the delivery paperwork, then shelve the sealed cartridges flat, away from sunlight and heat.

What does each cartridge in the set work out to?

The set is $296.93 for four cartridges, which averages $74.23 per cartridge. It is a blended figure — the black carries the longer 25,000-page rating and the colors 15,000 pages each — but it is the number to put on file when the next budget round asks what a full four-slot refresh costs. One order, one price, and every slot on the TASKalfa 3050ci covered in a single delivery.

What do I do with the empty cartridges from the set?

Keep them out of general waste. Slip each spent TK-8307 cartridge back into the box its replacement came in and collect the four together; most areas have a toner recycling drop-off or a waste hauler that takes spent cartridges, so one trip clears the whole set. Hold back any cartridge that failed early instead of recycling it — a faulty unit is covered on its own by the 1-year warranty with 1-year free returns.

About This Kyocera TK-8307 Four-Color Toner Set

This set restocks all four toner slots of a Kyocera-Mita TASKalfa 3050ci, 3051ci or 3550ci in a single order: the 25,000-page black TK-8307K plus the cyan, magenta and yellow TK-8307 cartridges at 15,000 pages each, for $296.93. It suits a supplies cabinet that serves one busy department — one delivery on the shelf, every color covered, and no mid-month scramble when a second or third slot reports low in the same week.
