A small physical device with pins that you press against the chip on the maintenance box.
If you try to reset the chip and it fails, do not panic. Check for these common issues:
| Advantages | Disadvantages | | :--- | :--- | | Cheaper than buying multiple replacement boxes. | Risk of Overflow: If you reset the chip but do not empty the physical pads, ink will eventually leak out of the printer. | | Convenience: No PC or drivers needed. | Warranty Void: Using non-OEM reset methods may void the Epson warranty. | | Eco-Friendly: Reduces plastic waste by reusing the box shell. | Chip Lifespan: Some chips have a "write limit" and may fail to reset after 2-3 attempts. |
