Variable Delay for Ink Jet Printer

This circuit relates to a continuously variable-time delay, controlled by a DC electrical level, that provides the means for conveniently and accurately adjusting the ink jet system synchronism.

As shown at Fig. 1, clock 1 provides two outputs designated A and B. The A signal is applied to the jet vibration circuit 2, whereas the B signal is applied to a drop charging circuit 3 via a variable-time delay 4. The variable-time delay consists of three single-shot multivibrators connected in series, as shown in Fig.
2. The maximum and minimum delay using this circuit is shown on the timing chart.
