Frequently Asked Questions

How can I tell from the old cartridge that this is the right one to order?

Pull the empty cartridge out and read its label. If the label carries part number 1T02MT0US0, or the TK-3112 name Kyocera also prints for this cartridge, this is the matching replacement. It is the black toner cartridge built for the FS-4100DN workgroup printer.

What arrives in the box?

A single factory-sealed black toner cartridge, packed ready to install. There is nothing to assemble and no separate parts to source — once the protective packaging comes off, the cartridge goes straight into the machine.

How far does a 15,500-page rating actually stretch?

The 15,500-page figure is the estimated yield of this one TK-3112 cartridge at standard page coverage. On a printer handling a few thousand pages a month of reports, statements and correspondence, that typically means several months between changes rather than weeks, which is why a lone cartridge suits offices that reorder as needed instead of stocking shelves.

Is fitting it a job I can do myself?

Yes. Open the front cover, slide the spent cartridge out, and take the new 1T02MT0US0 from its bag. Rock it gently side to side a few times so the toner settles evenly, remove the protective strip, push it in until it seats, and close the cover. The whole swap takes a couple of minutes with no tools and no service visit.

Why do the first prints look faint?

Toner can shift toward one end of the cartridge while it travels. Remove the cartridge, rock it side to side again, and refit it — the density normally comes back on the next run. Also make sure a toner-save or economy mode is not enabled in the driver. If output is still pale, get in touch and we will put it right under the warranty.

What cover do I get with this cartridge?

It is backed by a 1-year warranty and 1-year free returns, as detailed on our shipping & returns page. Orders ship from whichever of our warehouses in IL, PA, GA or CA is nearest to you, and support is available Monday to Friday, 9 AM to 5 PM CST.

My pages are mostly dense forms and reports — should I still expect 15,500 pages?

Expect fewer. The 15,500-page rating for the TK-3112 is measured at standard coverage, where only a small share of each page carries toner. Full-page forms, shaded tables and charts lay down far more toner per sheet, so the cartridge empties sooner. Light correspondence does the opposite. Judge the rating against your own page mix rather than treating it as a promise.

The low-toner warning has appeared — is the cartridge finished?

No. The FS-4100DN warns early, while usable toner still remains, precisely so you have time to act. Treat the message as your ordering cue rather than a stop signal: keep printing, and watch the output itself. When pages genuinely start to fade even after the cartridge has been rocked side to side, the 1T02MT0US0 is truly at the end of its life.

Should I discard the old cartridge as soon as the new one is fitted?

Hold on to it for a few days. Once the replacement TK-3112 has printed cleanly through several ordinary jobs, you can let the empty go with confidence. If anything about the new unit's output looks wrong in that first stretch, having the spent cartridge at hand makes the comparison easy and helps our support team pinpoint whether the cartridge or the printer is at fault.

What is the sensible way to get rid of the spent cartridge?

Slip the empty cartridge back into the bag and box the new one arrived in — that keeps any residual toner contained and the unit protected. From there, use an office-supply or electronics recycling drop-off in your area rather than general landfill waste. Toner cartridges are built from plastic and metal that recycling streams handle routinely, so the packaging swap takes seconds and closes the loop neatly.

About This Cartridge

Priced at $36.33, this single black cartridge is the no-fuss way to bring an FS-4100DN back into service: one sealed TK-3112 unit, rated at up to 15,500 pages, ordered under the exact 1T02MT0US0 part number printed on the cartridge it replaces. It is part of the Kyocera-Mita compatible range at Clever Supplies and is covered by the same 1-year warranty and 1-year free returns as the rest of that range.
