8. Programming the Contrast Sensors
There are two optional contrast sensors available for the SNAP 600 printer. 590011 is the
standard contrast sensor. It works well in most situations where there is significant contrast
between the material background and the sense mark. In situations where there is less
contrast between the material and the sense mark, or the material and sense mark are of
similar colors, the 590014 Color Contrast Sensor may be required.
Both sensors have to be “taught” the difference between the material background and the
sense mark. The procedures are similar, and are described below.
Programming the 590011 Contrast Sensor
The figure below shows the control panel for the 580011 Contrast Sensor. The sensor can
detect a light sense mark on dark material (L) or a dark sense mark on light material (D). In
each mode, the control switch can be set to RUN or TEACH.
To teach the sensor, thread the printer with the stock to be used. Position the material so that
a sense mark is just to the left of the sensor position. Adjust the sensor position across the
web so that the sensor lines up with the sense mark.
Set the control switch on the sensor to the TEACH position. If the material has a light sense
mark on dark material, set the switch to TEACH L. If the material has a dark sense mark on
light material, set the switch to TEACH D.
Press and hold the TEACH button while using the stock advance knob to move the sense
mark under and past the sensor.
