Frequently Asked Questions
What does "Type C7" mean in this set's name?
"Type C7" is the cartridge-family name Oki uses for this group of toner cartridges. The set sold under that name covers the four part numbers 42918904, 42918903, 42918902 and 42918901 — one cartridge per color — so ordering the Type C7 set and ordering by those four numbers amount to the same box.
What is inside the Type C7 set?
Four cartridges: black, cyan, magenta and yellow, each rated at up to 15,000 pages. The set is $292.17, which divides to about $73.04 per cartridge.
Which printers use Type C7 cartridges?
This cartridge group is listed for the Oki C9600hdn, C9600hn, C9600n and C9800hdn. If your machine belongs to that C9600/C9800 generation, the 42918901-through-42918904 numbers on your current cartridges confirm the match.
Can I fit the cartridges one at a time?
Yes — each is separately sealed. Replace the position the printer flags and keep the other three boxed; a Type C7 set is as useful as shelf stock as it is for a complete refresh.
Are these genuine Oki Type C7 cartridges?
These are compatible cartridges built to the 42918901, 42918902, 42918903 and 42918904 specifications, not Oki originals. They carry our one-year warranty, and returns are free for a year under our shipping and returns policy.
How do I get help before ordering?
Support runs Monday to Friday, 9 AM to 5 PM CST, and orders ship from our IL, PA, GA and CA warehouses. If you have your current cartridge numbers handy, the team can confirm the Type C7 set in one conversation.
