FS-3640MFP

Kyocera FS-3640MFP printer

Near the top of the 30-series monochrome MFP range, the Kyocera FS-3640MFP is engineered for floors where the machine rarely gets a quiet moment between jobs — print, copy and scan, plus a built-in fax that the tier below it does without. It feeds from the same cartridge as the 3040 and 3540 below it: the TK-352, factory number 1T02J10US0, also listed hyphen-free as TK352 and rated at approximately 15,000 pages per ISO/IEC 19752. Across the Atlantic the identical cartridge answers to the TK-350 label. One supply line therefore covers all three speed tiers of a mixed fleet.

Speed, stamina and Kyocera's long-life component design converge here. The office that chooses this model has usually stopped counting pages per day and started counting delays; a 15,000-page cartridge and a drum built for the long haul mean the machine's calendar has very few supply events on it, and the ones it has are visible weeks ahead on the level gauge.

Which cartridge should you buy?

Because the whole 30-series fleet drinks from one shelf, buying for this machine is really buying for the fleet. Standardize on one listing style for the storeroom — most offices keep the 2-pack as the working unit and a 5-pack in reserve — and every swap across the 3040, 3540 and 3640 becomes the same thirty-second task. There is no higher-capacity variant to graduate to; the standard cartridge is already a 15,000-page unit, so cost control comes from pack pricing and from never air-freighting a single cartridge in a panic. If your 3640 also carries the office fax traffic, budget consumption for received pages as well as printed ones.

Chip, toner and everyday use

Chip-based level reporting is what makes a shared fleet manageable: check the gauge during a weekly walk-past and reorder while there is still a cartridge of headroom. Ratings follow ISO/IEC 19752 on A4, so a floor printing legal-size or coverage-heavy forms should expect somewhat fewer pages per unit. Rocking a fading cartridge side to side redistributes toner for a final stretch of clean output, after which the reserve should already be on its way. Store cartridges in their packaging, flat and cool; a spare crushed under heavier boxes can arrive at the machine with a damaged seal. The compatible cartridges listed here are covered by a 1-year warranty and 1-year returns.

Frequently Asked Questions

Which toner does the Kyocera FS-3640MFP use?

The TK-352 cartridge (1T02J10US0), rated at approximately 15,000 pages per ISO/IEC 19752 — the same cartridge as the FS-3040MFP and FS-3540MFP.

What separates the FS-3640MFP from the FS-3540MFP?

Fax. The 3640 adds a built-in fax to the print, copy and scan functions of the 3540, aimed at busier floors. Supplies are unchanged — both machines take the TK-352.

Can one spare cartridge cover several different models on our floor?

Yes, and that is the design intent of this range: the TK-352 serves the 3040, 3140 and 3540 families as well as the FS-3920DN printer, so a single spare covers whichever machine calls first.

Are compatible TK-352 cartridges a safe choice for a machine this busy?

Yes. The compatible units on this page are engineered to meet or exceed factory specifications and are backed by a 1-year warranty and 1-year returns, so high-volume floors are not gambling on an unproven cartridge.
