Adjusting The Slack Detection Sensor - MUTOH VJ-1938TX Operation Manual

Adjusting the Slack Detection Sensor

The angles of the slack detection sensor and sensor reflector may not be aligned after adjusting the rails.
In the following case, adjust the angle of the slack detection sensor:
• If only the green lamp of the slack detection sensor turns on when the take-up unit is turned on.
(In a normal case, the orange and green lamps turn on at the same time.)
Note
If there are any objects between the slack detection sensor and sensor reflector, remove them and check the above item.
