The Epson R300 delivers reliable printing, but periodic maintenance routines can increase the waste ink counter and eventually trigger a ‘Service Required’ lock.

During head cleaning and maintenance cycles, excess ink is routed to internal absorber pads. The Epson R300 uses a software counter to estimate pad saturation and locks printing at a set threshold.
