Abstract
An ink reclamation receptacle receives ink purged from an inkjet printing apparatus. Ink in the reclamation receptacle wets a porous membrane positioned in the reclamation receptacle, and flows into a flow channel. Negative pressure applied to a port that is placed in fluid communication with the flow channel withdraws ink from the flow channel for use in the inkjet printing apparatus, while ink wetting the pores in the membrane resists a flow of air into the flow channel.
