Expected Output and Cartridge Yield
Page yields for OKI toner cartridges are tested under the ISO/IEC 19752 standard for monochrome laser printing at standard 5% page coverage. High-volume document workflows naturally deplete toner faster, making higher-capacity cartridges significantly more economical over the lifetime of your printer.

Frequently Asked Questions
Do the OKI B432dn and B512dn use the exact same toner cartridges?
Yes, both the OKI B432dn and B512dn share the exact same toner cartridge series (45807103, 45807107 and 45807112) and drum unit (44574303), making consumables fully interchangeable between both models.
Can I install the 12,000-page 45807112 extra high-yield cartridge in the OKI B432dn?
Yes, the 45807112 extra high-yield cartridge uses the same physical slot as the standard 45807103 and high-yield 45807107 cartridges, providing significantly more page output per replacement.
When do I need to replace the 44574303 drum unit versus the toner cartridge?
The toner cartridge supplies the black powder for printing, whereas the 44574303 drum unit transfers the image to the paper. The drum unit lasts roughly 23,000 pages-typically outlasting three to four high-yield toner cartridges before needing replacement.
How does printing coverage affect my actual page yield?
Quoted yields assume standard 5% page coverage (equivalent to a short letter). Printing dense text documents, detailed graphics or full-page black blocks uses more toner per page, reducing the total page yield accordingly.
