Abstract
An ink jet printer includes a catcher having a catcher plate along the lower portion thereof which is pivotally mounted for rotation about an axis parallel to a row of jet drop streams produced by the ink jet printer print head. A charge electrode plate, defining a plurality of notched charge electrodes, is movable between a drop charging position and a remote position. At start up and shut down of the printer, the charge electrode plate is maintained in its drop charging position when a deflection field is produced by a deflection electrode, so as to shield the drops from the deflection field. The catcher is pivoted into a full catch position at start up and shut down so as to catch substantially all of the drops produced by the relatively unstable jet drop streams.
