Frequently Asked Questions
How do I confirm this is the correct cartridge before ordering?
Pull the spent cartridge out and read the label on its top face. You are looking for two codes printed there: the Kyocera part number 1T02H00US0 and the TK-677 series name. When both match what is printed on your old unit, this single black cartridge is the right replacement — no other code needs to be checked.
What exactly shows up when the box arrives?
One individually sealed black toner cartridge, nothing more and nothing less. The price for this listing is $159.86 for that single unit. It comes wrapped so the toner stays settled and protected in transit; open the packaging only when you are standing at the machine and ready to install it.
How far does one cartridge actually go in a working office?
The TK-677 is rated at 20,000 pages per cartridge under standard test coverage. On a departmental copier that runs reports, invoices and copies all day, that rating translates into a long stretch between swaps. Dense pages with heavy black coverage will shorten it, light text pages will stretch it — the rating is the yardstick, your page mix decides the real number.
Can our office staff swap it without calling a technician?
Yes. Open the front cover, slide the empty unit out, unwrap the new 1T02H00US0 cartridge, give it a gentle side-to-side shake to loosen the toner, and push it in until it seats. The whole job takes a couple of minutes and needs no tools, so a stalled print queue rarely stays stalled for long.
The first copies after the swap look pale. Should I worry?
Usually not. Toner settles during shipping, so the first handful of pages can come out light. Take the cartridge out, rock it slowly from side to side five or six times to redistribute the toner inside, and reinstall it. Output normally evens out within a few pages after that.
What cover do we have if the cartridge misbehaves?
Every cartridge we sell in this range carries a 1-year warranty and 1-year free returns, handled under our shipping & returns terms. If a unit fails early, contact support Monday through Friday, 9 AM to 5 PM CST, and we will sort out a replacement or a refund.
How long will one TK-677 last on our KM-2540?
Divide your monthly page count into the 20,000-page rating. A departmental copier running reports, invoices and copies all day covers a long stretch between swaps — at 2,000 pages a month, one TK-677 lasts roughly ten months, while a busier machine printing 5,000 pages a month will see about four. Dense pages with heavy black coverage shorten the interval and light text pages stretch it, so the rating is the yardstick and your page mix decides the real number.
What does the 20,000-page rating assume about our pages?
It assumes standard test coverage — ordinary office pages, mostly text with normal spacing. Pages packed with dense black areas, solid headings or heavy graphics lay down far more toner per page than the test standard, so a form-heavy office will land under 20,000 while a light-text office runs closer to it. The rating stays useful as the comparison standard between cartridges; it simply is not a fixed count for every kind of document.
Should we keep a spare TK-677 on the shelf?
Yes, because a departmental copier rarely runs dry at a convenient moment. With one sealed TK-677 already on site, the next empty is a two-minute swap — open the front cover, slide the spent unit out, shake the new 1T02H00US0 cartridge gently side to side, push it in until it seats — instead of an urgent order plus a delivery wait while the print queue stalls. Stored sealed and only opened when you are standing at the machine, the spare waits patiently until its turn comes.
What should I do with the empty cartridge after the swap?
Keep it for a few days until the new TK-677 has printed cleanly through a normal run of work. If a fault shows up in that window, the old cartridge and its label help the conversation, since the 1T02H00US0 and TK-677 codes on it confirm exactly what was in the machine. Once the replacement has proven itself, the empty can go out with your local recycling or waste collection under whatever rules apply where you are.
