Waste ink recovery unit, printer, and waste ink recovery method

摘要

A maintenance unit 20 of a printer 1 has a waste ink recovery tank 24 that recovers waste ink. First and second mixing tubes 22A and 22B connect to the waste ink recovery tank 24. One mixing tube 22A branches into a tube BK and a tube Y, and the second mixing tube 22B branches into a tube C and a tube M. Black ink BK and yellow ink Y are merged and mixed in first mixing tube 22A before entering the waste ink recovery tank 24. The mixed inks from both mixing tubes then mix and flow together through a flow path 33 in the waste ink recovery tank 24. As a result, the chance of the ink inlets to the waste ink recovery tank becoming clogged by ink that has increased in viscosity can be reduced.
