Frequently Asked Questions
Does it make sense to keep a spare set on the shelf for the C9600HN?
If the printer cannot afford to sit idle, yes. Each cartridge in this set is rated at up to 15,000 pages, but a heavy week can still empty one without warning. A sealed spare set in the store room turns a toner emergency into a two-minute swap instead of a paused print queue.
How should unopened cartridges be stored?
Keep them sealed in their packaging, flat, in a cool dry cupboard away from sunlight and heat sources. Stored that way, cartridges wait patiently until the day the C9600HN asks for one — there is no benefit to opening them early.
What is in the box?
Four cartridges — black, cyan, magenta and yellow — from the 42918901, 42918902, 42918903 and 42918904 family, each one factory sealed and rated at up to 15,000 pages. That is every toner position in the machine covered by a single $292.17 order.
Which printers use this family?
The Oki C9600hdn, C9600hn and C9600n, together with the C9800hdn. Confirm by the cartridge number — 42918901, 42918902, 42918903 or 42918904 — on the unit you are replacing.
What does the set average out to per cartridge?
About $73.04 each across the four. Buying the colors as one set also means one shipment and one invoice, which is simpler for offices that expense printer supplies as a single line item.
What cover do I get with compatible cartridges?
A one-year warranty and one-year free returns on every cartridge, as set out in our shipping & returns policy. We dispatch from the nearest of our Illinois, Pennsylvania, Georgia and California warehouses, and support answers Monday through Friday, 9 AM to 5 PM Central.
