C15

Type C15 is the toner family behind Okidata's C610 line, and this page stocks the family's full shelf. The four cartridges are 44135304 black, 44135303 cyan, 44135302 magenta and 44135301 yellow, and every C610 variant in the family list below — from the base model to the networked and duplex versions — takes exactly the same set.

What makes this family's shelf distinctive is its depth in black. Text-heavy offices burn through black while the colors idle, so alongside the singles this page carries black in two, three and five packs and color sets running up to eight pieces. One cartridge family, sized several ways, lets a small office stock for its real printing pattern instead of a generic one.

Toner Cartridges for C15

Which cartridge should you buy?

Buy against the gauge, not the calendar. If black alone is low — the normal picture in a document office — a black multi-pack is the economical answer: the 2 Pack for a single printer, the 3 or 5 Pack where a C610 prints all day or several machines share one shelf. When one color is down, replace just that single; the other colors owe you their remaining pages. The full sets make sense when three or four cartridges are nearing empty together, or when restocking a spare shelf from zero — the larger sets simply stretch the interval before the next order.

Chip, toner and everyday use

Each cartridge is chipped and the printer reads its level continuously, so multi-packs can sit sealed until the moment they are needed. Keep spares flat, in their bags, away from sunlight and radiators. If a cartridge prints pale before its warning, take it out and rock it gently end to end — toner settles, and redistributing it often restores even coverage for the pages that remain. Fit cartridges one color at a time so each seats against its own contacts.

Frequently Asked Questions

Do the C610dn and C610dtn take the same cartridges as the C610?

Yes. The whole C610 family — base, CDN, DN, DTN and n variants — shares the Type C15 family: black 44135304, cyan 44135303, magenta 44135302 and yellow 44135301. The letters after the model name describe paper and network options, not different toner.

Which black pack size is right for a small office?

Start with the 2 Pack if the printer is one person's or a light shared machine. Move to the 3 or 5 Pack when black warnings arrive more than a few times a year — the cartridge is identical, only the count in the box changes.

Only one color has run out. Do I need a set?

No. Colors are independent slots; replace the single empty color and leave the healthy cartridges in place. Sets are for restocking or for printers where several colors finish together.

Is there a separate high-yield version of these cartridges?

The shelf here is built around one capacity per color, offered as singles and in multi-packs up to eight pieces. The practical choice on this page is pack size, matched to how fast your office actually prints.
