Abstract

A liquid collection device (30) includes a collection container (31), an absorber (32), and a solvent supplier (33). The collection container (31) collects liquid discharged from a liquid discharger (21). The absorber (32) absorbs the liquid collected in the collection container (31). The solvent supplier (33) supplies a solvent component of the liquid discharged from the liquid discharger (21) to the absorber (32).
