Frequently Asked Questions

What exactly arrives when I order this C9600 cartridge?

One black toner cartridge, part number 42918904, rated at 15,000 pages and priced at $83.87. This listing is the model-named single — the straightforward replacement for a C9600 that has just flagged its black toner as empty, with no spares bundled in. If you would rather have a spare waiting, the same cartridge is sold in 2, 3 and 5-packs, but what you see here is a single unit.

Why does black run out on its own schedule on a color printer?

Because black does disproportionate work. Text, line art, and the black layer of most color documents all pull from this one cartridge, while cyan, magenta and yellow only serve color content. On a C9600 that prints a lot of paperwork between its color jobs, the 42918904 emptying ahead of the color cartridges is the normal pattern, not a fault.

What does this single cartridge cost per page?

Divide the $83.87 price by the 15,000-page rating and you get about 0.56 cents per black page. Singles always carry the highest per-page figure in a cartridge family — the multi-packs of this same code trim it — but for a one-off replacement this is the complete, honest number.

Which printers is this the right black cartridge for?

The Oki C9600hdn, Oki C9600hn, Oki C9600n and Oki C9800hdn all take the 42918904. This page is titled for the C9600 models, and the C9800hdn shares the same black cartridge. Matching the number on your old cartridge to 42918904 is the surest confirmation before you order.

Is this a genuine Oki product?

It is not — it is a compatible cartridge produced to the 42918904 specification. It is covered by our one-year warranty, and our one-year free returns policy means a cartridge that does not work out comes back to us free. The policy wording is on our shipping and returns page.

When can I reach someone if I have a question first?

Support is staffed Monday to Friday, 9 AM to 5 PM Central, and orders ship from our Illinois, Pennsylvania, Georgia or California warehouses — whichever puts the cartridge on your doorstep soonest. A quick check with the team before ordering settles any doubt about the code.
