TASKalfa 3500i
Built for a department that measures output in thousands of pages a week, the Kyocera TASKalfa 3500i is a floor-standing A3 monochrome multifunction engineered around long-life components. It runs on the TK6307 black toner cartridge — Kyocera part 1T02LH0US0, sold in Europe as the TK-6305 — rated at approximately 35,000 pages per ISO/IEC 19752. That yield is the whole point of the TASKalfa line: the longer the cartridge lasts, the lower the cost per page across heavy monthly volumes.
Print, copy, scan and fax converge in one hardworking system that anchors a busy floor. The 3500i is the entry point to this six-model family, sized for departments whose document flow never really pauses — statements, case files, course packs, shipping paperwork. Because the engine is built from long-life parts, toner is the routine event in its life, not repairs; keeping this machine fed is a stocking decision, not a service decision. The compatible cartridges on this page are the ones it was designed around.

Which cartridge should you buy?
A 35,000-page rating changes the buying rhythm. A department printing 10,000 pages a month changes cartridges roughly once a quarter, so a single cartridge is a legitimate purchase — but a floor machine with no spare is a floor machine waiting to stop a whole team. The 2-pack is the practical default: one in the machine, one in the cabinet, reorder when the spare goes in. Print rooms running several family machines should look at the 5 and 10 packs, where one SKU covers every TASKalfa in this group and the per-cartridge cost falls with volume.
Chip, toner and everyday use
This is a big cartridge for a big machine, and the swap is still a one-person job: open the front cover, release the empty unit, and slide the replacement in until it locks. Rock the new cartridge gently before installing so the toner inside is loose and evenly spread. If the display questions the cartridge, reseat it once and check that the seal was fully removed — at this size, a cartridge resting a fraction short of home is the usual story. Keep the spare carton flat in a cool cabinet; heat is toner's enemy long before time is.
Frequently Asked Questions
Which toner does the TASKalfa 3500i use?
The TK6307 black toner cartridge (Kyocera part 1T02LH0US0), rated for approximately 35,000 pages. Order by the TK6307 number in North America; the TK-6305 is the same cartridge's European name.
Is the same cartridge used by the other models in this family?
Yes. The TASKalfa 3501i, TASKalfa 4500i, TASKalfa 4501i, TASKalfa 5500i and TASKalfa 5501i all take the identical cartridge, so one toner stock serves the entire 35/45/55-ppm group.
How long will one cartridge last in a busy department?
At the rated 35,000 pages, divide your monthly volume into 35,000: a 7,000-page month means roughly five months per cartridge. Heavy coverage — dense forms, shaded tables — shortens that, so high-volume floors should keep one spare ahead at all times.
Are compatible cartridges a safe choice for a machine this size?
The compatible cartridges on this page are built to the cartridge's factory specification and are covered by a 1-year warranty with 1-year returns, so the trial risk sits with us, not with your print room.
