Frequently Asked Questions

Why does this cartridge carry the number 44135304?

44135304 is the part number that identifies this exact black cartridge — one cartridge, one color, rated at 8,000 pages. The C610 family it feeds was sold under several model names (C610, C610dn, C610n, C610cdn and C610dtn), but the number is the one thing that never changes between them. If the cartridge coming out of your printer is stamped 44135304, this listing is its match; if the number differs, keep looking — a similar-looking Oki cartridge with a different number is a different part.

What arrives when I order this single cartridge?

One black compatible cartridge, sealed and ready to install. There is no color cartridge in the box and no set pricing involved — this is the plain single-unit listing at $45.89. Swap it in when your printer reports the black toner is spent, and the machine goes back to work. Because it is a single, it suits owners who replace toner as it runs out rather than keeping shelf stock.

How many pages should I realistically get from it?

The 44135304 is rated at 8,000 pages at standard coverage, which works out to roughly 0.57 cents per page at the $45.89 list price. Dense pages — solid graphics, heavy black fills, duplex reports — pull the real total down; light office text usually lands close to the rating. Treat 8,000 as the planning number and your own page mix as the adjustment.

Is this a genuine Oki cartridge?

No — it is a compatible cartridge built to the 44135304 specification, not an Oki-branded part. That is why it costs what it does. It is covered by our one-year warranty and one-year free returns; the full terms are on the shipping & returns page. If a compatible cartridge is not what you want, this is the honest point to choose the branded version instead.

My black prints are fading while the colors still look fine — is that normal?

Yes. On most C610-series machines black does the heavy lifting — text, forms, invoices — so the black cartridge empties well before the colors. Fading text with healthy color output is the classic signature of a spent black cartridge, and replacing just the black unit, this 44135304, is the correct fix. You do not need to touch the color cartridges until they report low themselves.

Where does my order ship from, and when is support available?

Orders ship from our warehouses in IL, PA, GA and CA, whichever puts the cartridge closest to you. Support answers Monday to Friday, 9 AM to 5 PM CST. The wider Oki range, including the color cartridges that sit alongside this black one, is on the Okidata brand page.
