Frequently Asked Questions

How do I identify this cartridge from the machine's supply information?

Check the supply status on the printer panel or pull the installed unit and read its label. The black cartridge across this TASKalfa range is the TK8309K, and matching that code is the reliable way to order — this single cartridge is $78.63.

Which TASKalfa models share this same black cartridge?

Four of them: the TASKalfa 3050ci, TASKalfa 3051ci, TASKalfa 3550ci and TASKalfa 3551ci. Kyocera specified one black unit — the TK8309K — for the whole group, which is why a single listing serves all four machines.

Does one cartridge really work in both the 3050ci and the 3551ci?

It does. These models differ in speed and features, but their black toner specification is the same TK8309K cartridge. If your machine is any of the four listed models, this is the black cartridge it was designed to take.

How far does a single cartridge go?

The TK8309K is rated at 15,000 pages at standard coverage. Routine office documents — correspondence, forms, statements, reports — track that number well. Pages with heavy fills, dense charts or large bold areas consume more toner, so high-coverage departments will see a shorter run.

What does the swap involve on these models?

Open the front cover, draw the spent cartridge straight out, prepare the new one with a gentle side-to-side rock, and slide it home until it seats. Close up and print a test page to confirm clean output. The whole job takes a couple of minutes and needs no tools.

What backing do I get, and how does delivery work?

The cartridge carries a 1-year warranty with free returns for a year, and support answers Monday through Friday, 9 AM to 5 PM CST. Orders ship from the nearest of our warehouses in IL, PA, GA and CA; times and return steps are set out on our shipping and returns page.

What does this cartridge cost per page?

At $78.63 for a 15,000-page rating, the TK8309K works out at just over half a cent per page at standard coverage. That is the figure to use when you are budgeting a print-heavy quarter: multiply your expected page count by it and you have the toner cost of the run. Heavy fills, dense charts and large bold areas will push the real figure up, so treat the rating as the yardstick for ordinary office documents, not a promise for solid-fill work.

How many months should one cartridge last in my office?

Divide 15,000 by your monthly page count. An office printing 500 pages a month will see about two and a half years from a single TK8309K; at 2,000 pages a month it is closer to seven or eight months. The simplest way to check your own number is to note the fitting date on the box and the page count when the low warning first appears — after one cartridge you will know your real monthly rate instead of estimating it.

How do I tell a genuinely empty black from a cartridge that just is not seated right?

Print a test page. If the black areas are pale across the whole sheet, with no streaks or bands, the toner is spent and a fresh TK8309K is the fix. If the page shows a sharp pale band or a streak in one place while the rest is solid, lift the cartridge out, rock it gently side to side to level the toner, and seat it firmly again — a settling or seating issue clears in a page or two, while a truly empty cartridge stays pale no matter how often you reseat it.

Is one spare worth keeping if I only run a single machine?

Yes, and this cartridge makes it easy: the same TK8309K fits the TASKalfa 3050ci, 3051ci, 3550ci and 3551ci, so one sealed spare on the shelf protects whichever of the four you own. A black empty in the middle of a print run is a two-minute swap when the spare is already in the room, and a stalled printer while a delivery is in transit. Keep the spare sealed and flat, and let the day you fit it be the day you order its replacement.
