Specification Description: This chip, model 45807111, is specifically designed for the OKI B432/492dn series monochrome laser printers. The color designation “MONO” represents black-and-white single-color printing. The capacity is marked as 12K, indicating support for approximately 12,000 pages of printing under standard test conditions (A4 size, 5% coverage). The version designation “EU” is suitable for models marketed in the European region.

Version Description: The chip version refers to the firmware or regional code it is compatible with. The EU version is designed for printers sold in the European region and differs from other versions such as NA (North America) and WW (Worldwide) in communication protocols or encryption methods. Please ensure to select the version that matches your printer’s regional settings; otherwise, it may result in recognition failure or limited functionality.

Installation Notes: This chip is compatible with OKI B432/492dn printers. If this is a toner cartridge chip, ensure that the toner has been refilled to the rated capacity before replacement; otherwise, the chip may fail to initialize correctly or prematurely indicate insufficient toner. If this is a drum unit chip, ensure that the drum assembly has no physical damage and the photoconductor drum surface is intact during replacement to avoid equipment error codes or counting abnormalities.
