1.7 Various Sensors
Feed Gap Sensor
The feed gap sensor detects a label gap to locate the starting print position of the next
label. The sensor is mounted 4 mm off the center line of the main mechanism.
In case of Label
Black Mark Sensor
The black mark sensor locates the position of label by emitting infrared rays onto the
black mark at the back of the ticket. The sensor is mounted 5.75 mm off the center line
of the ticket roll width on the mechanism.
