Frequently Asked Questions

What cartridges does the Oki C9800N require?

The C9800N takes black 42918901, cyan 42918902, magenta 42918903, and yellow 42918904. This wide-format-capable color printer uses the same four-cartridge logic as the rest of the family.

My C9800N prints large color areas with banding. Is that a toner problem?

Banding on large color areas often comes from a depleted color cartridge, so check the 42918902, 42918903, and 42918904 levels first. If banding persists with full cartridges, the image drum for that color channel may be due for replacement.

Should I replace all four C9800N cartridges at the same time?

No. Each color depletes at its own rate, so replace only the empty one. Replacing all four together wastes toner that is still usable in the remaining cartridges.
