Frequently Asked Questions
How do I know this box holds the right four cartridges for my printer?
Check the codes on the box against the ones your machine calls for: black 1T02KT0US0 (TK-582K), cyan 1T02KTCUS0 (TK-582C), magenta 1T02KTBUS0 (TK-582M) and yellow 1T02KTAUS0 (TK-582Y). Those four codes are the complete TK-582 set for the FS-C5150DN, one cartridge of each color, so a single order renews every slot in the machine.
Why is the black cartridge rated for more pages than the colors?
Kyocera rates the TK-582 black at 3,500 pages and each color at 2,800 pages, both at the standard 5% coverage. Most office pages are text, so the black cartridge does the heavy lifting and is built with the larger rating. In practice the colors often last longer in calendar time, because a typical document covers far less of the page in color than it does in black text.
Do all four cartridges have to go in at the same time?
No. Each unit is sealed separately, and swapping a color that still has life in it wastes the pages it has left. Fit only the cartridge the printer is asking for, keep the rest sealed in the box, and draw them down one slot at a time as the machine calls for them.
What does the $66.92 price actually cover?
All four cartridges — one black and one of each color — in a single shipment. There is nothing else to buy to complete the set, and keeping the four codes together in one box means the next change is a trip to the supply shelf instead of another order and another wait for delivery.
How should the unopened cartridges be kept?
Flat in their sealed bags, in a cool, dry cabinet away from windows and radiators. Heat and direct light age toner even through the packaging. When you do open one, rock it gently from side to side a few times before fitting so the toner spreads evenly across the cartridge.
If one cartridge from the set fails, does the whole box go back?
No — each cartridge is covered on its own, so only the faulty unit needs attention while the other three stay in the printer or on the shelf. Every cartridge in this set carries a 1-year warranty and 1-year free returns, with the full terms laid out on our shipping & returns page.
Which fading pattern points to which cartridge in this set?
Each slot announces itself differently. Text turning gray and weak points at the black 1T02KT0US0. Blues washing out and greens losing depth mean the cyan 1T02KTCUS0 is low. Reds going muddy and faces turning orange implicate the magenta 1T02KTBUS0, while greens sliding toward blue and highlights losing warmth mean the yellow 1T02KTAUS0 has run down. Matching the symptom to the code before you open the box means you fit the one cartridge that is actually empty.
How do the set's ratings hold up on color-heavy work?
The color ratings of 2,800 pages each are measured at 5% coverage of that color — a modest logo or a few chart bars. A full-page photograph can lay down ten times that amount of a single color, so a run of photo printing can draw a color cartridge down in a fraction of its rated count. The black's 3,500-page rating behaves the same way on dense pages. Treat the numbers as the comparison standard they are, and expect calendar life to follow your coverage, not the headline figure.
Is there a sensible order for working through the box?
Let the printer set the order — it will ask for the black first in most offices, then whichever color your documents lean on hardest. Note each fitting date on the box as you go; that simple record shows your real consumption pattern after one full cycle, so the next set can be ordered before the last cartridge is fitted rather than after. The box is stock, not a schedule: slots are renewed one at a time, exactly when each one empties.
What should happen to each cartridge as it comes out empty?
Keep each empty until its replacement has printed cleanly for a few days, then send it to a toner recycling collection point or office-supply take-back bin rather than general trash. Empties leave one at a time, matching the way the set is consumed — a black empty this month, a color empty later. Holding a faulty unit back from recycling matters too: a cartridge that failed early is covered on its own under the set's 1-year warranty, and having it to hand makes that claim straightforward.
About This TK-582 Four-Color Set
This set brings the four TK-582 cartridges for the Kyocera FS-C5150DN together in one carton: TK-582K black rated at 3,500 pages, and TK-582C, TK-582M and TK-582Y rated at 2,800 pages each. Each cartridge is sealed on its own, so the box works as a small rotating stock — fit what is empty today, hold the rest for the next change. It is a compatible set built to the original TK-582 specifications and sold under our Kyocera Mita compatible range. Orders leave from our warehouses in IL, PA, GA and CA, and if you want the codes double-checked before ordering, our support team is available Monday to Friday, 9 AM to 5 PM CST.
