碧砚W1620A/X鼓芯片参数说明
适用机型：以上芯片仅适用于 HP LaserJet Pro 4007n / 4007dn / 4007dw / MFP 4113dw / 4113fdn / 4113fdw，请勿用于其他机型。
颜色：MONO（黑白激光打印）
参数内容说明：
- 容量：”3K” 表示该芯片支持约 3,000 页打印量（基于 ISO/IEC 19752 标准，A4 纸 5% 覆盖率下估算）；”10K” 表示约 10,000 页打印量。实际页数受打印介质、覆盖率及打印环境等因素影响，存在一定偏差。
- 版本（Version）：EUR/MEA 指该芯片版本适用于欧洲（Europe）、中东（Middle East）及非洲（Africa）地区销售的对应机型。不同地区固件版本可能存在差异，跨区使用可能导致识别失败或计数异常。
产品类型：此为鼓芯片（Drum Chip），用于 HP 4007 系列激光打印机成像鼓单元的计数、身份识别及故障状态记录。
使用注意事项：
更换鼓芯片时，必须确保硒鼓单元物理状态完好，无严重磨损、感光鼓划伤或显影组件脏污。若在硒鼓异常情况下更换芯片，设备可能无法正常初始化或持续出现硬件故障代码（如 50.1、51 等错误）。芯片本身不参与成像过程，不影响打印质量。

Biyan W1620A/X Drum Chip Specifications
Compatible Models: These chips are exclusively compatible with HP LaserJet Pro 4007n / 4007dn / 4007dw / MFP 4113dw / 4113fdn / 4113fdw. Do not use on other models.
Color: MONO (Black & White Laser Printing)
Specifications:
- Capacity: “3K” indicates approximately 3,000 pages (estimated per ISO/IEC 19752 standard, A4 paper at 5% coverage density); “10K” indicates approximately 10,000 pages. Actual page yield may vary depending on factors including print media, coverage density, and operating environment.
- Version: EUR/MEA denotes that this chip version is compatible with corresponding models sold in the Europe, Middle East, and Africa (EMEA) regions. Firmware versions may differ across regions, and cross-regional usage may result in recognition failure or counting anomalies.
Product Type: This is a Drum Chip designed for counting, identification, and fault status recording of the imaging drum unit in HP 4007 series laser printers.
Usage Notes:
When replacing the drum chip, ensure the imaging drum unit is in good physical condition, free from severe wear, photoconductor drum scratches, or developer unit contamination. If the chip is replaced while the imaging drum is in abnormal condition, the device may fail to initialize properly or continuously display hardware fault codes (such as errors 50.1, 51, etc.). The chip itself does not participate in the imaging process and has no impact on print quality.
