Programming the Color Contrast Sensor
The configuration switch on the panel has three positions:
Q1 – Teaching mode
Run – Run mode
Run Delay – Do not use
To teach the sensor:
1. Thread the printer with the stock to be used.
2. Position the material so that a sense mark is just to the left
of the sensor position.
3. Adjust the sensor position across the web so that the sensor
lines up with the sense mark.
4. Set the control switch on the sensor to the Q1 position.
5. Press and hold the TEACH button while using the stock advance knob to move
the sense mark under and past the sensor.
Make sure that the stock is tight against the web
guide. The best way to do this is to press the TEACH
button with the left index finger, while applying back
tension to the supply roll with the left thumb. This
ensures that the stock is in the same position that it
will be when the printer is running.
6. Release the TEACH button.
• If the Q/ok light flashes rapidly, the sensor did not program correctly. If the
process fails repeatedly, the sensor may not be lined up correctly with the sense
mark, or there may not be enough contrast between the background and the
sense mark.
7. Move the material so that the sense mark moves back and forth under the
sensor. The Q/ok light on the sensor should flash when the sense mark passes
under the sensor.
8. Move the configuration switch to RUN position.
