Epson L6490 Resetter Extra Quality -

Resetting the software does not remove the physical ink from the sponges inside the printer. If you reset the printer multiple times, the ink will eventually overflow and damage the internal components or ruin your desk surface. It is strongly recommended to physically clean or replace the waste ink pad pads after the first or second reset.

To actually execute the reset down to 0%, you must purchase a one-time use "Reset Key" online (usually costing around $10 USD). epson l6490 resetter
