Epson PM-A820 Waste Ink Counter Reset

If your Epson PM-A820 suddenly refuses to print and shows a maintenance warning, it is often caused by the waste ink (ink pad) counter threshold.

During head cleaning and maintenance cycles, excess ink is routed to internal absorber pads. The Epson PM-A820 uses a software counter to estimate pad saturation and locks printing at a set threshold.
