Frequently Asked Questions
Why fit a complete set on a C9800 used for color work?
Color output is only as consistent as the weakest cartridge. Fitting black, cyan, magenta and yellow together — all from the 42918901, 42918902, 42918903 and 42918904 family, all fresh — means the four colors age in step, which keeps tones predictable across long runs of brochures, proofs and presentations.
What does the box hold?
Four individually sealed cartridges, one per color position, each rated at up to 15,000 pages. The set is $292.17, so a full color refresh of the C9800 is a single order rather than four separate purchases.
Which printers does this cartridge family serve?
It is listed for the Oki C9600hdn, C9600hn and C9600n, and for the C9800hdn in this model's family line. Check the number on the cartridge you remove — 42918901, 42918902, 42918903 or 42918904 — for a certain match.
How quickly will heavy color coverage eat through the ratings?
Noticeably quicker than text printing. The up-to-15,000-page figure assumes light coverage; a page of full-bleed color can consume several times as much toner, so a graphics-led C9800 should budget for shorter cartridge life than the headline number suggests.
What is the per-cartridge cost?
Averaged across the box, about $73.04 per cartridge. For a machine producing customer-facing color, that average is the number to weigh against the cost of reprinting work spoiled by a fading cartridge.
What backing comes with the set?
One-year warranty and one-year free returns on all four compatible cartridges, set out in our shipping & returns policy. We ship from the closest of our Illinois, Pennsylvania, Georgia and California warehouses, with support available Monday through Friday, 9 AM to 5 PM Central.
