In a continuous ink jet printer for use with pigmented ink, the entrance to the ink path (), () from the interior of the ink tank () to the ink pump () is made up of a plurality of small inlet openings, which may be provided by nozzlesformed in a shroudthat fits around an ink filter () in the ink tank (). The openings are provided at the bottom of the ink tank (), close to the floor, and face parallel to the floor or at least partially towards it. If the ink pump () is driven in reverse, any ink in the ink path is driven at speed out through the inlet openings into the interior of the ink tank (), followed by air.
