CS-4501I

Offices that run the Copystar CS-4501I rarely run it alone. It is the refreshed twin of the CS-4500I in Kyocera's monochrome copier platform — Copystar being the badge Kyocera sells under in the United States — and like every machine in that platform it takes a single black cartridge, the TK-6307 (1T02LH0US0). This page stocks the cartridge singly and in 3 pack and 5 pack form, including a Premium Quality 5 pack listing, so the same order can cover this machine and the relatives it shares a supply shelf with.

The practical value of a one-cartridge platform shows up in the supply cupboard. The CS-4501I, the earlier CS-4500I, the smaller CS-3500I and CS-3501I, the larger CS-5500I and CS-5501I and the Kyocera-badged TASKalfa equivalents all draw the same TK-6307 off the shelf, so there is one cartridge to stock, one code to remember and no wrong-cartridge orders for a mixed fleet. When a cartridge arrives in a Kyocera Mita box for a machine wearing a Copystar badge, that is not a mix-up — it is the same manufacturer supplying its own platform under its two names.

Which cartridge should you buy?

Start from how many machines the purchase has to cover. For a lone CS-4501I in light use, a single cartridge or a 3 pack is plenty, and the 3 pack leaves a spare ready for the day the machine stops mid-job. Where this model shares a shelf with sibling machines on the platform — a common setup, since fleets were often bought in waves — the 5 pack listings make more sense, because one empty cartridge anywhere in the fleet is replaced from the same box. Both 5 pack listings hold the same TK-6307 cartridges; the Premium Quality listing is simply the alternative version of the five-pack, so reorder consistently from one of them.

Chip, toner and everyday use

On a shared fleet shelf, rotation matters as much as storage. Use the oldest spare first so cartridges do not sit sealed for years, write the arrival month on the box if your office goes through them slowly, and keep boxes flat in a dry cupboard away from radiators and sunlit windows. The cartridge's chip is read by the machine to confirm the cartridge and follow its toner level, so a spare that has been shelved correctly goes in and registers without fuss. If a freshly installed cartridge is not recognized, reseating it firmly is the first thing to try before treating it as faulty.

Frequently Asked Questions

Does the CS-4501I take the same toner as the CS-4500I?

Yes. The 4501I is the refreshed version of the same platform, and the cartridge did not change between them: both machines run the TK-6307 (1T02LH0US0), and the same cartridge also serves the rest of the family listed below.

Can one spare cartridge cover both a CS-4501I and a TASKalfa 5501i?

It can. The TASKalfa models are the Kyocera-badged twins of this Copystar platform, and the cartridge specified for them is the same TK-6307. A single spare on the shelf genuinely covers both badges, which is the quiet advantage of this platform for mixed fleets.

Why does the cartridge box say Kyocera when my machine says Copystar?

Because Copystar is Kyocera's United States brand. The machine and the cartridge come from the same manufacturer; the listings are titled Kyocera Mita because that is the manufacturer's own name for the TK-6307 line. The badge difference is branding, not compatibility.

How long can I keep a spare TK-6307 before using it?

A sealed cartridge keeps well when it is stored flat, dry and at ordinary room temperature, away from heat sources and direct sunlight. Fleets that stock the multi-packs should rotate them oldest-first, so no cartridge spends an unreasonable time on the shelf before it is installed.
