Epson L4166 Waste Ink Counter Reset

The Epson L4166 is a widely used Epson printer. Like many Epson devices, it can stop printing when the internal waste ink counter reaches its predefined limit.

During head cleaning and maintenance cycles, excess ink is routed to internal absorber pads. The Epson L4166 uses a software counter to estimate pad saturation and locks printing at a set threshold.
