Frequently Asked Questions

Which of the family's codes belongs to the black cartridge?

The black is 1T02LC0US0, also marked TK-8507K — the code in this family with no letter group in the middle. If the code on the cartridge you are removing reads 1T02LC0US0, this $124.73 replacement is the one for that slot.

Why is the black rated at 30,000 pages when the colors are rated at 20,000?

Because the black unit is the larger workhorse cartridge of the family. Text and everyday office documents lean almost entirely on black, so Kyocera's design for this platform gives the black slot the bigger fill. The 30,000-page figure is its rated yield at standard coverage — the benchmark for a cartridge that, in most offices, is changed more often than any color despite the higher rating.

Is this a full-capacity cartridge or a small starter unit?

Full capacity. This is the standard replacement cartridge rated at 30,000 pages, not a reduced-fill starter of the kind that ships inside a new printer. A starter can run out surprisingly fast; this one is the full-size refill the machine takes for the rest of its working life.

My first prints after fitting look pale. Should I be worried?

Usually not. Pull the cartridge back out, rock it slowly from side to side to level the toner inside, refit it firmly and run a few pages. Fresh cartridges commonly print light for the first sheet or two and then settle to full density on the TASKalfa 4550ci. If pages stay gray after a dozen prints, contact us rather than forcing anything.

Can I swap it myself, or does it need a technician?

You can do it yourself in a couple of minutes. Open the front cover, slide the old black unit out, remove the seal from the new one, slide it in until it clicks and close the cover. No tools, no settings to change, and the color cartridges stay exactly where they are.

What protection do I get with this cartridge?

A 1-year warranty with 1-year free returns, covered by our shipping & returns policy. If the cartridge develops a fault inside that year, it is dealt with on its own — there is no need to involve the rest of the set.

What does the black work out to per page at its rated yield?

At $124.73 for a TK-8507K rated at 30,000 pages, the rated cost comes to about 0.42 cents per page at standard coverage. Dense work — financial statements with heavy tables, bold headers and shaded forms — will sit above that figure, while plain correspondence tracks close to it. For budgeting, the useful habit is to cost your black supply on the rated figure, then adjust once your own page counters show how your document mix compares with the test standard.

How many months should one black cartridge last at our volume?

Divide the 30,000-page rating by the pages your machine prints in a month. At roughly 1,500 pages a month, a TK-8507K is a twenty-month cartridge; at 3,000 a month it lasts about ten months; a hard-working department at 6,000 a month will see around five months from it. Those are standard-coverage estimates — a workload heavy in graphics and solid fills shortens them — but they turn the rating into a calendar you can plan purchases around.

Is a spare black worth holding when the rating is already this high?

Yes, because the black is still the cartridge these machines change most often: everyday documents lean almost entirely on black, so the 1T02LC0US0 turns over faster than any color despite carrying the largest fill in the family. One sealed spare on the shelf converts the next empty black from a stalled queue and a rush order into a two-minute swap, and a sealed cartridge waits in a normal office cupboard without any attention until its turn comes.

What do I do with the empty black cartridge afterwards?

Hold on to the spent TK-8507K until the replacement has run cleanly through a few days of ordinary printing; with the old unit still available, any early problem with the new one is straightforward under the 1-year warranty and 1-year free returns. After that, the empty goes out through whatever route your office already uses for used toner cartridges — there is no special handling it needs, beyond keeping it boxed so loose toner stays contained.
