*These are OKI’s published yields for its listed small-capacity original toner cartridges, based on A4 page yield compliant with ISO/IEC 19798. They are not a specification for every compatible or remanufactured option; check the individual product listing for its own yield and terms. See OKI’s official C301dn consumables and part numbers and C321dn consumables and part numbers.
Check the model before you order
OKI lists these four codes for both the C301dn and C321dn. The earlier version of this page included a much longer list of C-series and MC-series printers; do not rely on that list alone. Check the complete model name on the printer label or in its settings, then compare it with the cartridge code. If the label shows another model, search by that exact model before buying.
The printer also uses an image drum, which is a separate consumable from toner. OKI lists image drum code 44968301 for the C301dn; confirm your model and the item requested by the printer before ordering a drum.
Find the right replacement
- Read the full code on the old cartridge, including its colour.
- Choose original, compatible or remanufactured only after checking the exact model and the product’s own specification, price and returns information.
- Use the product-only search for OKI 44973536, or search the other colour codes individually.
