Epson S21 Reset Waste Ink Counter
The service-required message on Epson S21 often relates to the internal waste ink counter rather than an empty cartridge or paper fault. The steps below help you confirm and resolve that condition.
Understanding the Epson S21 waste ink warning
Every cleaning cycle sends a small amount of ink to the waste ink system. Epson S21 adds that activity to its counter and displays a maintenance warning when the programmed threshold is reached.
Wic Reset Connect is designed to reset the compatible counter in Epson S21. The physical waste ink system should still be inspected and maintained when necessary.
