44574903为碧砚品牌推出的OKI B431系列激光打印机兼容芯片，用于替代原装硒鼓或粉盒上的计数芯片。该芯片支持读写打印机固件中的耗材计数信息，需配合对应机型使用。
上述参数及芯片适用于 OKI B431 机型。
参数说明：
- 品牌：指芯片所适配的原装设备品牌，本产品为 OKI（冲电气）兼容芯片。
- 型号：44574903，对应原装芯片型号。
- 颜色：MONO，表示单色打印芯片，仅支持黑色碳粉/硒鼓计数。
- 容量：10K，理论打印量为10,000页（基于ISO标准测试页面覆盖率，实际用量因打印内容而异）。
- 版本：TW，台湾地区（Taiwan）专用版本，不同区域版本间固件数据格式可能不同，请勿跨区混用。
版本使用提示：TW版本仅适用于台湾地区销售的OKI B431机型，其他区域（如WW通用版、NA北美版）可能存在兼容性问题，请根据实际采购地区选用对应版本。
更换注意事项：
若本产品为粉盒芯片，请在加注足量碳粉后再更换芯片。未加粉或碳粉不足时更换芯片，可能导致芯片写入失败或打印机提前提示耗材耗尽。
若本产品为硒鼓芯片，请确认硒鼓感光鼓、充电辊等组件完好无损后再行更换。硒鼓老化或损坏时更换芯片，可能导致芯片无法正常初始化或出现故障代码。

44574903 is a compatible chip for the OKI B431 series laser printers launched by the Biyan brand, designed to replace the counting chips on original equipment manufacturer (OEM) toner cartridges or drum units. This chip supports reading and writing consumable counting information in the printer firmware and must be used with the corresponding printer model.
The above parameters and chip are applicable to the OKI B431 printer model.
Parameter Description:
- Brand: Refers to the original equipment manufacturer brand that the chip is compatible with. This product is a compatible chip for OKI (Oki Electric).
- Model: 44574903, corresponding to the OEM chip model.
- Color: MONO, indicating a monochrome printing chip that only supports black toner/drum counting.
- Capacity: 10K, theoretical print yield of 10,000 pages (based on ISO standard test page coverage; actual yield may vary depending on print content).
- Version: TW, a Taiwan region (Taiwan) exclusive version. Firmware data formats may differ between regional versions; do not mix versions across regions.
Version Usage Note: The TW version is only applicable to OKI B431 models sold in the Taiwan region. Other regional versions (such as the WW universal version, NA North America version) may have compatibility issues. Please select the corresponding version according to the actual procurement region.
Replacement Precautions:
If this product is a toner cartridge chip, please add sufficient toner before replacing the chip. Replacing the chip without adding toner or with insufficient toner may cause chip writing failure or cause the printer to prematurely indicate consumable depletion.
If this product is a drum chip, please ensure that the drum photoconductor drum, charging roller, and other components are intact before replacement. Replacing the chip when the drum is aged or damaged may cause the chip to fail to initialize properly or result in error codes.
Copyright Notice: Biyan brand chips are compatible consumable chips and are not directly associated with the OKI/Oki Electric OEM brand. They do not involve any original factory technical authorization.
Company Introduction: Caiyi Office Consumables, established in 2008, primarily deals in printer chips, toner cartridges, drum units, toner powder, and other accessory businesses.
