Installing exclusive drivers is different from standard .exe files. Follow this exact sequence:

⚠️ Do not use generic Realtek HD Audio drivers from Realtek.com. They lack the custom DSP (Digital Signal Processor) configuration for the 3102’s onboard amplifier.

If you (some legacy models used that numbering), please confirm the full model number from the printer label (e.g., Lenovo 3102C). I can then provide an accurate driver feature for that device.
