产品概述
碧砚LD2051系列鼓芯片为兼容联想至像C205DNW、CM205DNW系列彩色激光打印机的硒鼓计数芯片，用于硒鼓使用寿命的识别与计数管理。本系列涵盖标准容量与高容量两种规格，覆盖KCMY四色通道。
产品清单
标准容量版
高容量版
以上芯片均为鼓芯片（Drum Chip），产品品牌为碧砚，适用于联想（Lenovo）至像 C205DNW、CM205DNW 机型，版本区域为 CHN（中国大陆）。不适用于上述列表以外的其他机型。
参数说明
- 型号：芯片产品编号。LD2051为标准容量系列，LD2051H为高容量系列（H代表High Yield）。后缀字母K/C/M/Y对应四色通道。
- 颜色：K=黑色（Key）、C=青色（Cyan）、M=品红色（Magenta）、Y=黄色（Yellow），对应打印机四色硒鼓独立计数通道。
- 容量：数值表示芯片预设的硒鼓额定打印页数。例如1.5K即约1500页，3K即约3000页，测试条件为A4幅面5%覆盖率标准。
- 版本（CHN）：CHN为中国大陆区域版本，芯片固件适配中国大陆销售机型的区域识别协议。不同区域版本（如WW通用版、NA北美版等）之间通常不互通，需根据设备销售区域选择对应版本芯片。
- 类型（鼓）：本系列为鼓芯片，安装于硒鼓单元上，用于记录硒鼓累计使用页数及寿命状态，与粉芯片（记录碳粉余量）功能不同。
注意事项
鼓芯片更换时需确保硒鼓本身状态完好。若硒鼓已出现鼓芯磨损、刮痕、充电辊老化或废粉仓满等问题，仅更换芯片仍可能出现打印质量异常或设备报错代码。建议在硒鼓整体状况良好的前提下进行芯片更换操作。
安装前请确认芯片型号、颜色通道与打印机区域版本均匹配，区域或型号不匹配可能导致设备无法识别芯片。
更换芯片时请按照设备原有安装方向操作，避免芯片触点损坏或接触不良。

Product Overview
The Biyan LD2051 series drum chips are compatible drum counting chips designed for Lenovo Zhixiang C205DNW and CM205DNW series color laser printers, used for drum unit service life identification and page count management. This series covers both standard yield and high yield specifications, spanning all four KCMY color channels.
Product List
Standard Yield Version
High Yield Version
All chips listed above are drum chips. The product brand is Biyan, compatible with Lenovo Zhixiang C205DNW and CM205DNW models, with the regional version designated as CHN (Mainland China). These chips are not compatible with any models outside the list above.
Parameter Description
- Model: The chip product number. LD2051 denotes the standard yield series, while LD2051H denotes the high yield series (H stands for High Yield). The suffix letters K/C/M/Y correspond to the four color channels.
- Color: K = Black (Key), C = Cyan, M = Magenta, Y = Yellow, corresponding to the four independent counting channels of the printer’s color drum units.
- Yield: The numerical value indicates the chip’s preset rated drum page yield. For example, 1.5K represents approximately 1,500 pages, and 3K represents approximately 3,000 pages, based on the standard test condition of A4 paper size at 5% coverage.
- Version (CHN): CHN is the Mainland China regional version, with chip firmware adapted to the regional identification protocol for models sold in Mainland China. Different regional versions (e.g., WW for Worldwide, NA for North America, etc.) are generally not interchangeable. The corresponding regional chip must be selected based on the region where the device was sold.
- Type (Drum): This series consists of drum chips, installed on the drum unit to record the drum’s cumulative page usage and service life status. This function differs from that of toner chips, which record remaining toner levels.
Precautions
When replacing the drum chip, ensure the drum unit itself is in good condition. If the drum unit already exhibits issues such as OPC drum wear, scratches, charge roller aging, or a full waste toner compartment, merely replacing the chip may still result in print quality abnormalities or device error codes. It is recommended to perform chip replacement only when the overall condition of the drum unit is satisfactory.
Before installation, please confirm that the chip model, color channel, and printer regional version all match. A mismatch in region or model may result in the device failing to recognize the chip.
When replacing the chip, follow the original installation orientation of the device to avoid damage to the chip contacts or poor electrical connection.
