产品清单（产品品牌：碧砚芯片）
以上型号均适用于 Great Wall/长城 品牌打印机，版本区域统一为 CHN。
参数与版本说明
- 颜色标识：MONO 代表黑色（Mono Black），适用于单色激光打印设备。
- 容量标识：K 代表千页（基于ISO/IEC 19752标准，A4幅面5%覆盖率测试页）。1.5K/3K/3.5K 为粉盒对应标称打印页数，10K 为硒鼓组件对应标称寿命。
- 版本区域：CHN 代表中国大陆地区版本。该版本芯片的通信协议与计数逻辑已针对大陆地区发售的对应机型进行匹配，跨区域使用可能导致识别异常或功能受限。
- 类型区分：列表明确区分“粉芯片”与“鼓芯片”。粉芯片用于记录碳粉余量及粉盒认证；鼓芯片用于记录感光鼓寿命及成像组件状态。
安装与使用注意事项
粉盒芯片更换提示：更换粉盒芯片前，请务必确保粉盒内已加满碳粉。若在碳粉不足或未加粉状态下直接更换新芯片，芯片将无法正确初始化，可能导致不生效或提示数值不满。
鼓芯片更换提示：更换鼓芯片前，请确保硒鼓组件物理状态完好。仅在硒鼓完好或已完成规范保养的情况下更换，才不容易出现设备故障代码。

Product List (Brand: Biyan Chips)
All models listed above are compatible with Great Wall brand printers, with the region version uniformly designated as CHN.
Parameter and Version Notes
- Color Designation: MONO stands for Monochrome Black, applicable to monochrome laser printing devices.
- Yield Designation: K represents thousands of pages (based on the ISO/IEC 19752 standard, A4 format at 5% coverage test page). 1.5K / 3K / 3.5K correspond to the rated page yield of the toner cartridges; 10K corresponds to the rated service life of the drum unit.
- Region Version: CHN denotes the China mainland version. The communication protocol and page-counting logic of chips for this version have been specifically matched to the corresponding printer models distributed in mainland China. Cross-regional use may result in recognition errors or restricted functionality.
- Type Distinction: The list clearly differentiates between “Toner Chips” and “Drum Chips.” Toner chips are used to monitor remaining toner levels and perform toner cartridge authentication; drum chips are used to track the photoconductive drum service life and monitor the status of the imaging unit.
Installation and Usage Precautions
Toner Chip Replacement Notice: Before replacing the toner chip, please ensure that the toner cartridge has been fully refilled with toner powder. If a new chip is installed with insufficient toner or without any toner, the chip will not initialize correctly, which may result in activation failure or inaccurate toner level readings.
Drum Chip Replacement Notice: Before replacing the drum chip, please ensure that the drum unit is in sound physical condition. Replacement should only be performed when the drum unit is intact or has undergone proper maintenance, in order to prevent device error codes.
Copyright Notice: The chips manufactured by our company are compatible aftermarket chips and have no direct affiliation with the original equipment manufacturer (OEM) brand.
