CS-3501I

On the front panel it says CS-3501I, on the cartridge box it says Kyocera Mita, and both are correct: the CS-3501I is a monochrome multifunction copier from Copystar, which is Kyocera's brand name in the United States. The cartridge to look for is TK-6307, part number 1T02LH0US0, stocked below as a single, a three pack, a standard five pack and a premium five pack. If you arrived here from a search on the part number rather than the model, you are in the right place — the label on the cartridge you just removed is the most reliable guide to this page.

This machine belongs to a wide family of near-identical copiers wearing two different badges. The same platform appears as the Copystar CS line on this page and as the Kyocera TASKalfa line elsewhere in the store, and the family list at the bottom runs to eleven models. That breadth is convenient — one cartridge shelf can feed several machines in the same building. The cartridge code does not change with the badge: the Kyocera TASKalfa listings carry the same TK-6307 as the Copystar listings here, so the safe habit is simply to confirm the code on the old cartridge every single time.

Which cartridge should you buy?

If this is the first cartridge you have bought for the machine, start with the single: it confirms the code in hand and covers the machine while you learn how fast it uses toner. Offices that already know their rhythm usually move to the three pack, which keeps one cartridge installed, one spare and one in reserve. The five pack is the fleet choice — several machines from this family in one building can all draw on the same box — and the premium five pack holds the same five cartridges in the premium-quality grade. Every option is the same TK-6307 cartridge, a compatible cartridge backed by a one-year warranty and one-year returns, so there is no wrong answer on fit, only on quantity.

Chip, toner and everyday use

Before the new cartridge goes in, read its label once more against the one you removed — on this platform that ten-second check is what confirms the box in your hand carries the TK-6307 code the machine expects. Slide the cartridge in until it seats and the copier will register it on its own. A few gentle rocks side to side before installing spread the toner for even coverage from the first page. Keep the removed cartridge in the new one's box until you are sure the replacement prints cleanly; if a problem appears, having the old unit at hand makes the comparison immediate instead of a guess.

Frequently Asked Questions

My machine says Copystar but the cartridge says Kyocera — is that right?

It is. Copystar is the name Kyocera sells under in the United States, so the cartridges for a CS-3501I are Kyocera Mita listings. The badge on the door and the brand on the box describe the same company's machine and supplies.

Does the cartridge code change between the Copystar and Kyocera badges?

No. Read the cartridge that is in the machine now: this Copystar page stocks the TK-6307, and the same platform listed under the Kyocera TASKalfa badge carries the same TK-6307 code. Ordering by the printed code removes all doubt.

Does the cartridge from our TASKalfa 4501i fit this copier?

The TASKalfa 4501i sits in the same family as the CS-3501I, and the family shares the same black cartridge — its listings carry the same TK-6307 code as this page, so the cartridge itself is the same supply; checking the code printed on it before swapping boxes between machines is still the quick way to be certain.

Single or three pack for a machine that is used lightly?

For light use, the single is the sensible buy: toner keeps best inside a working machine or a sealed box, and a lightly used copier may take a long while to finish even one cartridge. Move up to the three pack when changes start coming around regularly.
