It is the part number, and it identifies this as Kyocera's black toner cartridge for its heavy-duty monochrome printers. Matching that number to the one on the cartridge you are replacing is the surest way to know you have the correct unit in hand before anything is opened.
A full-size one. This TK3122 carries the family's standard 21,000-page rating — the same capacity as the cartridge a machine ships with once its initial unit is used up, not a reduced sample size. Ratings follow the usual standard test pages, so heavy page coverage lowers the real-world total.
It is built for the ECOSYS M3550idn. Because that model prints in black only, there is exactly one cartridge type to keep track of, and this is it — no color variants of the same number exist to confuse the order.
That the carton label reads TK3122 and the cartridge's seal is intact. Give the box a quick look for transit damage before signing off on the delivery, and keep the cartridge in its wrapping until the moment you fit it — the seal is what keeps the toner settled and the contacts clean.
Usually not. Take the cartridge out and seat it again firmly, then let the printer finish its start-up routine and print a few pages; the level reading normally settles once the new unit has been recognized and run briefly. If the message persists after a reseat and a short run, contact us while the cartridge is still near full.
A 1-year warranty and 1-year free returns stand behind it. Our support team is on hand Monday through Friday, 9 AM to 5 PM CST for anything from a fitting question to a cartridge that underperforms.
At the purchase price of $35.77 against the rated 21,000 pages, the arithmetic lands at roughly 0.17 cents per page under standard test coverage. Real pages vary — a dense form costs more toner than a short memo — so treat the figure as a planning number rather than a promise. Even allowing for heavier coverage, the TK3122 sits in the fraction-of-a-cent range that makes high-capacity monochrome printing cheap to run, which is why cost per page rarely decides anything on this class of machine.
At the first low-toner warning, not when the machine stops mid-job. The warning arrives with useful pages still left in the cartridge, and that margin is your delivery window. Offices that want a firmer trigger can note the page counter once a month: once you know roughly how many pages a month the M3550idn turns out, the counter reading at install tells you within a few weeks when the next order should be placed, long before output starts to fade.
Usually, yes. As a cartridge empties, the remaining toner settles unevenly, so pages fade while usable toner is still inside. Take the unit out, rock it gently from side to side several times to redistribute what is left, and refit it — density often returns for a worthwhile extra run of pages. Treat those pages as borrowed time, though: the fade will come back, and the moment it does is the moment the replacement order should already be moving.
Pages with heavy toner coverage: full-page forms, dense tables, bold graphics and large solid headings all lay down far more toner than an ordinary text letter. The 21,000-page rating assumes light, standard test coverage, so a diet of coverage-heavy documents will land well short of it, while plain correspondence can meet or exceed it. If your output is mostly dense paperwork, judge the cartridge by your own page counter history rather than the headline rating when planning reorders.
At $35.77, this is the single-cartridge order for an ECOSYS M3550idn that needs toner now: the TK3122 in its full 21,000-page capacity, ready to fit straight from the box. It ships from our warehouses in IL, PA, GA and CA, with delivery and returns information on our shipping & returns page.
