When the Epson WorkForce 321 reaches its maintenance threshold, Epson firmware may block printing as a safeguard. In most cases, this is resolved with a counter reset.

During head cleaning and maintenance cycles, excess ink is routed to internal absorber pads. The Epson WorkForce 321 uses a software counter to estimate pad saturation and locks printing at a set threshold.
