Frequently Asked Questions

How can I be sure TK352 is the cartridge my machine takes?

Go by the number, not by how the printer looks. Pull the cartridge that is in the machine now and read its label, or open the supply status page on the panel — the machine calls for the TK352. This single black cartridge is $32.98, and if the number on your old unit matches, you are ordering the right part.

What does a 15,000-page yield mean for a small office?

That figure comes from standard test pages with ordinary text coverage. A small office printing letters, invoices and reports will land near it; pages dense with forms, logos or shaded tables use toner faster and bring the real total down. Either way, one cartridge covers a long stretch of everyday printing before you think about toner again.

Do I need a technician to change it?

No. Open the front cover, slide the spent cartridge out, unpack the TK352, give it a gentle side-to-side rock so the toner settles evenly, and seat it until it clicks. The whole swap takes about two minutes with no tools, and the copier is back in service as soon as the cover closes.

The first pages after installing look faint. Is the cartridge bad?

Usually not. Remove it and rock it gently a few times to redistribute the toner, then print several regular pages — output normally evens out quickly. If prints stay light or streaked after that, contact us; help is available Monday through Friday, 9 AM to 5 PM CST.

How fast will this single cartridge get to me?

Orders leave from our warehouses in IL, PA, GA and CA, so the shipment starts from whichever location is nearest you. Transit times and the full return process are laid out on our shipping and returns page.

What protection comes with it?

Every TK352 we sell is covered by a 1-year warranty, and returns are free for a full year as well. If the cartridge underperforms at any point in that window, you are not stuck with it — reach out and we will make it right.

What does this cartridge cost per page at its rated yield?

At $32.98 for a cartridge rated at 15,000 pages, the arithmetic works out to about 0.22 cents per page at standard test coverage. Real pages covered in dense forms or shaded tables cost a little more than that because they draw toner faster, while plain letters and reports land close to the rated figure. Either way, it is a useful yardstick when you compare this TK352 against the per-page cost of a service contract or a smaller cartridge.

If I buy a second TK352 as a shelf spare, how should I keep it?

Leave it sealed in its box, stored flat in a cool, dry spot out of direct sunlight and away from heat sources. Toner powder does not dry out or go stale the way liquid ink does, so a spare bought this quarter is still ready when the installed cartridge runs out months later. When its turn comes, give it the same gentle side-to-side rock described for a fresh install so the toner settles evenly before it goes in.

What do I do with the old cartridge once the new one is printing well?

Keep the spent TK352 in its box for a few days while the replacement proves itself, then send it out through whatever toner recycling or disposal route your office already uses. If the new cartridge misbehaves in those first days, contact us before discarding anything — support is available Monday through Friday, 9 AM to 5 PM CST, and having the units on hand makes any warranty conversation under the 1-year coverage much simpler.

When is the right moment to order the next cartridge?

At the first low-toner warning, not when pages start coming out blank. The warning appears while useful toner still remains, which gives a delivery time to arrive: orders leave from our warehouses in IL, PA, GA and CA, dispatched from whichever is nearest you. Ordering on the warning rather than on empty keeps the FS-3040MFP in service continuously, and if you prefer zero risk, keeping one sealed spare on the shelf removes the timing question altogether.
