Abstract
There is described a printing head useful in an ink-jet printer to print on a recording medium, comprising jet forming means for forming spaced drops of ink, charging means adjacent the forming means for inducing an electric charge in selected some of the drops, the charging means being mounted on an electrically non-conductive plate, and drop-catcher means for catching the charged drops. The drop-catcher means is integral with the plate mounting the charging means, and is disposed downstream from the charging means. The head is improved in that the drop-catcher means is provided with a face exposed to the drops that has a predetermined slope with respect to the jet stream of uncharged drops that provides a greater separation distance between the drop-catcher means and the uncharged drops, near the beginning of the stream, than such separation distance near the end of the stream adjacent the recording medium, and means at the edge of the face of the drop-catcher means, adjacent to the charging means mounting plate, for preventing build-up of ink adjacent that edge.
