Frequently Asked Questions
How do I verify TK421 is the code my copier takes?
Check the label on the cartridge currently in the machine, or the supply list in the copier's manual. The KM 2550 is built around the TK421, so if that code is what you find, this two-pack is the correct refill.
What does a 15,000-page rating mean for a copier that runs all day?
Each TK421 cartridge is rated at 15,000 pages at the standard 5% coverage. On a departmental copier, that translates into long intervals between changes — the cartridge is sized for sustained daily copying rather than occasional use, which is precisely why holding a spare matters when it finally runs out.
Why pair a working cartridge with a sealed spare?
A copier that stops mid-morning usually stops a whole team's work. With the second TK421 already in the building, the changeover is measured in minutes and the copying queue clears the same hour instead of waiting on a delivery window.
How is the swap carried out on the KM 2550?
Open the front panel, release and draw out the spent cartridge, then slide the fresh TK421 in until it locks and close up. It is a clean, tool-free change designed to be done by whoever is standing at the machine — no service visit required.
How should the spare be kept in a copy room?
Still sealed, lying flat, and away from the heat the copier itself gives off. A shelf or cupboard at normal room temperature is fine; just avoid storing it on top of the machine or next to a radiator.
What protection backs this two-pack?
Each cartridge is covered by a 1-year warranty and 1-year free returns, judged individually. If either unit ever lets you down, our shipping & returns page explains how the return or replacement is arranged.
What does each cartridge in the pair cost?
The two-pack is $145.29, so each TK421 stands at $72.65. Between them the cartridges carry 30,000 rated pages, which puts the running cost at about 0.48 cents per page at the standard 5% coverage the rating assumes. For a shared KM 2550 that is a tidy planning figure: multiply it by the machine's monthly page count and the toner line in the department budget is done.
Does everything the copier produces draw on this one cartridge?
Yes — copies and prints alike come out of the same TK421; there is no separate supply for different jobs on the KM 2550. That is why the machine's total page count, not any single job type, is what empties a cartridge. Work that never reaches paper, like scanning a document to send electronically, touches no toner at all and does not shorten the cartridge's life.
The low-toner warning appears mid-morning — should the spare go in straight away?
Not usually. The warning is timed to leave working room, and the installed TK421 will normally finish the day's queue before output actually suffers. Watch the copies rather than the message: when pages begin to fade, the sealed spare goes in — a change of a few minutes, done by whoever is at the machine. Swapping at the first warning simply discards toner the cartridge still holds.
What do we do with the cartridge that comes out?
It goes into the packaging the fresh TK421 arrived in, which contains any residue, and then out through your local recycling or disposal route rather than loose into a bin beside the copier. If the unit came out faulty rather than empty, hold on to it until you have spoken to us — each cartridge in the pair is judged on its own under the warranty.
