Why choose the genuine OKI 45439002 toner cartridge
The 45439002 is a genuine OKI toner. The powder is matched to the fuser and speed of these printers: sharp text, even solids, proper fusing from the first page, and a cartridge recognized immediately (levels shown, no error message). It is designed for OKI LED printers, whose fixed print head requires an even toner powder for consistent output across the page width.
When to replace it
The printer shows a message when the part's counter reaches end of life (Supplies status or Reports menu). Replacing it then avoids downtime and wear on other parts.
Printers compatible with the 45439002
The 45439002 is compatible with the following models and series (manufacturer data):
- B731dn
- B731dnw
Check the exact reference of your printer (label or Information menu); suffixes are variants of the same series and generally use the same consumables. If in doubt, send us the exact model.
Page yield
36,000 pages (manufacturer data, about 5% coverage). Graphics or photo-heavy pages reduce the actual yield. The cost per page shown next to the price is calculated from the current price and this yield.
Installation
Tool-free replacement: open the cover, remove the used cartridge, take the new one out of its bag, rock it gently to distribute the toner, remove the protections, then insert until it clicks. The printer recognizes the cartridge. The used cartridge is recycled through the manufacturer's take-back program or your local collection.
Use and tips
The 45439002 suits intensive or shared use: the cartridge (36,000 pages) lasts over 10 years at 300 pages per month and over 3 years at 1,000 pages per month.
Store the cartridge in its packaging, flat, away from light and humidity, and unpack it only when installing. At the "Low" alert, order: the printer keeps printing until the replace message. Genuine cartridges preserve the printer's warranty.
