Positioning the Automatic Film Tracking Sensors
Automatic film tracking automatically keeps the edges of the film tube
even. In order for automatic film tracking to work effectively, the
automatic film tracking sensors must be positioned relative to the film
web after the film tracking path has been established.
This procedure describes how to position the automatic film tracking
sensors relative to the position of the film web. At this point, the film
tracking path should have been established.
To position the sensors, use the adjustment knob to move the sensors
so that the inner sensor is blocked by the film web and the outer
sensor is not blocked by the film web.
Note:
Each sensor is equipped with a status LED (mounted on the
film carriage frame or inside of the electrical cabinet).
