Frequently Asked Questions
Which cartridges are in this box?
Four cartridges, one for each slot: TK542K black, TK542C cyan, TK542M magenta and TK542Y yellow. The codes are printed on every cartridge label, so when one slot runs low you can pull the matching color out of the box and leave the rest sealed until their turn comes.
Why is the black rated at 5,000 pages while each color is rated at 4,000?
Those are the per-cartridge ratings for this family: the TK542K black is rated at 5,000 pages and each of the TK542C, TK542M and TK542Y colors at 4,000 pages, all at standard coverage. It simply means black is filled for a longer run; a color cartridge that empties sooner is behaving normally, not underperforming.
Do all four cartridges have to go in at the same time?
No. The slots work independently, so install whichever color the printer is asking for and keep the other cartridges in their sealed packaging. A full four-color change is only worth doing when several slots are running low together; replacing a cartridge that still has toner left just throws pages away.
A new cartridge is printing streaky on its first pages. What should I check?
First, that the protective seal was pulled all the way out before fitting, and that the cartridge was pushed home until it seated firmly. Then print several dense color pages. A fresh cartridge sometimes needs a short run before the toner distributes evenly and the streaks clear.
How should the cartridges I am not fitting yet be stored?
Keep them sealed in their original packaging, lying flat, in a dry room away from direct sunlight and heat sources. Stored that way, the spares wait without any attention until the printer calls for them — there is no benefit to opening a cartridge early.
What cover comes with this set?
Every cartridge in the set is covered by a 1-year warranty with 1-year free returns under our shipping & returns policy. The cover is per cartridge, so a problem with one unit never affects your rights on the other three.
How do I check the set is complete when it arrives?
Count four cartridges and read the code on each label before you shelve the box: one TK542K black, one TK542C cyan, one TK542M magenta and one TK542Y yellow. The labels make the check quick, and catching a missing or duplicated color on delivery day is far easier than discovering it months later when a slot runs dry and the box holds the wrong cartridge.
Which cartridge in the set is likely to run out first?
That depends on what the printer actually does. On text-heavy paperwork the black works hardest, even though the TK542K carries the higher 5,000-page rating. On brochure and presentation work the colors drain faster, and one color often leads the others down — the one your documents lean on most. Watch the supply readings rather than guessing, and replace only the slot the printer asks for.
What does standard coverage mean for how long this set lasts?
The ratings — 5,000 pages for black and 4,000 for each color — are measured at standard coverage, a typical mix of text and modest graphics. Pages dense with color use far more toner than a letter, so a month of full-color flyers can draw a color cartridge down well ahead of its rating, while light office printing can stretch the set considerably further. Treat the ratings as a planning guide, not a promise.
Four cartridges will eventually come out of the printer. How should I handle the empties?
As each spent cartridge comes out, put it straight into the packaging its replacement arrived in and keep the empties together in one spot. That keeps toner dust contained and makes the eventual trip to a recycling collection point a single errand instead of four. Because the cover on this set runs per cartridge, an empty that turns out to have failed early can still be dealt with on its own.
This is a complete four-slot refresh for the Kyocera FS-C5100DN: one TK542K black rated at 5,000 pages plus one each of the TK542C cyan, TK542M magenta and TK542Y yellow cartridges rated at 4,000 pages apiece, priced at $152.84. It suits a printer whose colors have aged together and reached the end of their run at roughly the same time. The set is part of our compatible Kyocera-Mita range, orders ship from our warehouses in IL, PA, GA and CA, and support is available Monday to Friday, 9 AM to 5 PM CST if you would like the codes checked against your old cartridges before you order.
