Frequently Asked Questions

What exactly is inside this two-pack?

Two individual black TK5152K toner cartridges, each sealed in its own packaging. There is no oversized double cartridge — you install one now and keep the second on the shelf as a ready spare. The pair sells for $51.93.

Why buy two at once instead of one?

Because toner never runs out at a convenient moment. With a sealed TK5152K waiting in the supply cabinet, a low-toner warning becomes a two-minute swap instead of a stalled print queue while you wait on a delivery.

Which printers do these cartridges go in?

They are built for the M6035cidn and the M6535cidn. If either of those models sits in your office, the TK5152K is the black cartridge it takes — confirm the code on the label of the cartridge you are replacing.

How long will the spare keep on the shelf?

A long time, as long as it stays sealed, flat, and out of heat and direct sunlight. Toner does not dry out the way liquid ink does, so a spare bought today is still ready when the installed cartridge finally fades months from now.

Each cartridge is rated at 12,000 pages — what does that mean in practice?

That figure comes from standard test pages at modest coverage. Everyday memos, invoices and reports land close to it; dense pages with heavy graphics and bold blocks will use toner faster and shorten the run.

What protection covers both cartridges?

Each one carries a 1-year warranty and 1-year free returns, and if the second cartridge turns out to be the problem months later, the coverage still applies. Questions along the way? Support answers Monday through Friday, 9 AM to 5 PM CST, and orders ship from our warehouses in IL, PA, GA and CA.

How can I tell whether the first cartridge is really empty before I fit the spare?

Watch the output and try the gentle fix first: as a TK5152K nears its end, text fades unevenly, and removing the cartridge and rocking it side to side redistributes the remaining toner for a final run of pages. When fading returns quickly after that, the cartridge is genuinely spent and the spare's turn has come. That borrowed-pages trick is also your signal to make sure a further replacement is on order.

Is it worth noting when each cartridge goes in?

Yes — write the install date on the box of the cartridge you fit. Two cartridges at 12,000 rated pages each give this pair a long combined life, and the dates turn your real consumption into a number: pages between installs, at your office's coverage, tells you whether one cartridge lasts you two months or six. That knowledge is what makes the next two-pack purchase a planned order instead of a reaction.

We run both printer models — can this pair be split between them?

Yes. The TK5152K is the shared black cartridge for the M6035cidn and the M6535cidn, so the two cartridges in this pack can go one into each machine, or both into whichever printer works harder. Offices that split the pair usually keep a note of which machine received which cartridge and when — with a shared code across two models, that small record prevents a great deal of shelf confusion.

What should I do with the empty cartridge when the spare goes in?

Box it in the spare's packaging immediately and send it for recycling or disposal. The moment of the swap is when mix-ups happen: two identical-looking TK5152K cartridges, one full and one spent, side by side by the printer. Clearing the empty away at once leaves only the working cartridge in the machine and, if you reorder promptly, a fresh sealed spare on its way to the shelf.

About This Two-Pack

This is the working pair for a single busy printer: one TK5152K in the machine, one sealed beside it. Together they keep an M6035cidn or M6535cidn running through the next toner change and the one after that, with no emergency orders in between. Delivery timing and return steps are spelled out on our shipping and returns page, and the full Kyocera-Mita range is there if your office runs other models too.
