Abstract
Among other things, a device for use in printing is described. The device comprises a first chamber for receiving a liquid and a first filter member in the first chamber. The first filter member separates the first chamber into a first part and a second part laterally adjacent to the first part. The first filter member comprises pores having an average size. The pores are configured to filter the liquid passing from the first part to the second part. The first filter member further comprises an opening adjacent to a top of the first chamber for air to pass from the first part to the second part. The opening has a size at least 10 times larger than the average size of the pores. There is a first inlet in fluid communication with the first part and a first outlet in fluid communication with the second part.
