Abstract
A system for recycling waste phase change ink in a phase change ink imaging device includes a waste ink collector positioned within a phase change ink imaging device to collect waste phase change ink produced by a printhead in the phase change ink imaging device. The waste ink collector includes a heater for heating the waste phase change ink in the collector to at least a phase change ink melting temperature. A waste phase change ink conveyor is configured to convey melted waste phase change ink from the waste ink collector to an ink reservoir for the printhead.
