Frequently Asked Questions
The cartridge we pulled out is stamped 1T02HG0US0 — is this listing that same cartridge?
Yes. 1T02HG0US0 is the part number Kyocera prints on the cartridge itself, and TK-572K is the series name the same black cartridge is sold under. If the unit you removed carries either marking, this is its like-for-like replacement — same black toner, same fit, no adapters or workarounds involved.
What does the 16,000-page rating mean in a real office month?
The 16,000 pages are measured at the industry-standard 5% page coverage, which is close to a typical text page. An office printing around 150 pages of letters, invoices and reports a day would work through roughly 3,000 pages a month, so one cartridge can cover five months or more of ordinary monochrome output before the low-toner warning appears.
Is this a full-capacity cartridge or a small starter unit?
It is a full-capacity cartridge rated for the complete 16,000 pages. Printers often ship with a reduced-fill starter cartridge that runs out surprisingly fast; this replacement is filled to the full TK-572K specification, so the first replacement cycle lasts noticeably longer than the one the machine came with.
Our print is fading on the left side but fine on the right — is the black finished?
Usually not. Uneven fading across the page normally means the remaining toner has settled to one side of the cartridge. Take the unit out, rock it gently from side to side four or five times to redistribute the toner, and refit it. On the FS-C5400DN that simple step typically restores even density for the rest of the cartridge's life.
When should we order the next one?
When the low-toner warning first appears is cutting it close for a busy office; the sensible trigger is keeping one sealed spare on the shelf and reordering at $72.90 as soon as that spare goes into the machine. That way a cartridge running dry mid-run never stops a print job while a delivery is in transit.
What protection comes with this cartridge if it underperforms?
Every cartridge we sell in this range carries a 1-year warranty and 1-year free returns, with the full conditions set out on our shipping & returns page. If a unit leaks, streaks or simply stops being recognized well inside its rated life, you are covered without having to argue page counts.
What does this cartridge work out to per page?
At the listed $72.90 for a full 16,000-page rating, the TK-572K lands at roughly 0.46 cents per page at standard 5% coverage — under half a cent for the black on an ordinary text page. That figure is the useful way to judge the cartridge: not the size of the box, but what each invoice, letter and report costs in toner. Pages heavier than the standard test page pull the real figure up somewhat, and light text-only work pulls it down.
Which kinds of documents eat into the 16,000 pages fastest?
Anything that lays black across more of the sheet than a normal text page does. Dense forms with shaded boxes, pages carrying large charts or graphics, and full-page black backgrounds consume several times the standard amount per sheet. A month of plain letters and invoices will track close to the rating, while a month of presentation printing can shorten the cartridge's calendar life noticeably even at the same page count — coverage, not the counter, is what drains the 1T02HG0US0.
How should the sealed spare be stored so it is ready when needed?
Keep it sealed in its bag, lying flat, in a cool dry cupboard well away from radiators and sunlit windows. Toner is a dry powder and keeps patiently in those conditions for many months, but heat and damp work against it. When the day comes to fit the spare, rock it gently from side to side a few times first — toner settles during storage, and that simple motion levels it before the cartridge starts work.
What do I do with the old cartridge once the new one is in?
Hold on to it for the first few days while the replacement proves itself across your normal work. Once the new TK-572K is printing cleanly, the empty goes to a toner recycling collection point or an office-supply take-back scheme rather than the general trash. If the new unit ever gives trouble early in its life, contact us before disposing of anything — the old cartridge is useful evidence, and every unit in this range is covered individually by its 1-year warranty.
