Abstract (en)
An improved catcher device is provided for use with a continuous ink jet printer of the kind for generating a row of parallel selectively charged drop streams catches charged ink drops. The improved catcher device includes a catcher face (20) for receiving selectively charged drops of ink. A catcher radius (28) associated with the catcher face directs the flow of selectively charged drops of ink from the catcher face into a catcher throat (22). The catcher throat is associated with the catcher radius and accepts a flow of selectively charged drops of ink from the catcher radius. The catcher throat (22) has a short, narrow gap (34) with a sudden enlargement (36) downstream of the gap and two converging-diverging channels (33) formed by an elliptical island (30) and elliptical sidewalls. Finally, a catcher vacuum port (26), comprising the catcher face (20), the catcher radius (28), and the catcher throat (22), establishes reduced airflow and returns the selectively charged drops of ink from the printhead to the fluid system. <IMAGE>
