Frequently Asked Questions

This headline says CLT-609S, but the cartridge I removed is stamped CLT-K609S — same thing?

Yes. CLT-609S is the family name for this generation of Samsung cartridges, and the letter inside the code tells you which color position it fills: K is black. So the CLT-K609S in this listing is exactly the black cartridge your printer is asking for; the cyan, magenta and yellow positions carry their own codes within the same 609S family.

What should the first pages look like after I fit it?

Expect the first few prints to settle in quickly: text should be dense and even, with no streaks or pale bands. If early pages look light, remove the CLT-K609S, rock it gently side to side to redistribute the toner inside, and refit it — that almost always evens out a fresh cartridge. Output that stays patchy after that is a reason to contact us, not to live with it.

Which machine does this listing serve?

It is the black cartridge listed for the Samsung CLP-770ND. If your printer's cartridge door or manual names the CLT-K609S code, this is the supply it takes. Matching on the code rather than the printer's marketing name is the reliable way to reorder, because the code identifies the cartridge itself.

We print in black and white most of the time — what does that do to the color cartridges?

Very little. A page sent to the printer as monochrome is produced by the black cartridge alone; the three colors sit that page out. That is why the CLT-K609S can be exhausted by correspondence while the colors barely move, and why setting internal drafts to greyscale is the simplest way to keep color toner for the work that genuinely needs it.

How far does the 7,000-page rating stretch in a shared office?

Shared machines consume faster than most people expect, because everyone's small jobs add up. At a combined 30 pages a day the CLT-K609S lasts roughly seven to eight months; at 80 pages a day it is closer to three months. Reading the page counter when you fit the cartridge and again a month later turns the guess into a date you can order against.

How are returns and warranty handled on this cartridge?

Simply: the purchase is protected by a twelve-month warranty if a defect shows up, and returns are free throughout that same first year if the cartridge is not right for any reason. Details are set out on the shipping and returns page. Orders are dispatched from our warehouses in IL, PA, GA and CA, and help is available weekdays between 9 AM and 5 PM CST.

About This CLT-609S Black Cartridge (CLT-K609S)

The code on the cartridge is the surest guide to reordering, and this listing is the black it points to: a compatible CLT-K609S rated at 7,000 pages and priced at $70.71 — a little over a cent a page at standard coverage. It serves the CLP-770ND as the text-and-paperwork half of a four-cartridge color system, and you can browse the rest of that system in our Samsung toner cartridges collection. One year of warranty cover and free returns for a year come with it as standard.
