Frequently Asked Questions
What does this C9800HDTN set cost per printed page?
The set is $292.17 for four cartridges, about $73.04 each, and each cartridge is rated at up to 15,000 pages. That works out to roughly half a cent per page for any single cartridge at standard coverage — or just under two cents for a full-color page drawing on all four. For a high-volume machine, that is the number that keeps toner from eating the department budget.
What arrives in the box?
Black, cyan, magenta and yellow cartridges — one of each — sold under the part numbers 42918901, 42918902, 42918903 and 42918904. One order therefore refreshes every color position in the C9800HDTN in a single delivery.
Is one set enough stock for a machine that prints in bursts?
At 15,000 rated pages per cartridge, one set covers a long run between orders, but burst-heavy environments often keep a second set as a buffer so a big job never stalls waiting on delivery. Unopened cartridges store well, so the buffer costs nothing but shelf space.
Which printers share this cartridge group?
Alongside the C9800HDTN, the set is listed for the Oki C9600hdn, C9600hn, C9600n and C9800hdn. The safe verification is always the part numbers: 42918901, 42918902, 42918903 and 42918904 against the cartridges in your machine.
Are these cartridges remanufactured or compatible?
They are compatible cartridges built to the 42918901-series specifications, sold with a one-year warranty and one-year free returns. If a cartridge fails inside that window, our shipping and returns policy covers the remedy.
How do deliveries work for a busy print room?
Orders leave from our IL, PA, GA or CA warehouses, whichever is closest. Support is available Monday to Friday, 9 AM to 5 PM CST for order questions or help confirming the right set before a big run.
