7.0 SENSORS
There are four sensors and a switch that detect media (labels), ribbon and thermal head position.
Figure 15. Location of Sensors and Switch
Sensor Type and Functions:
NOTE:
1.The Media Gap Sensor works with the Black Line Sensor, so both sensors must be positioned in line. The Black Line Sensor consists of both direct reflective sensor unit for black line sensing and photo emitter for the Media Gap Sensor.
2.The Ribbon Sensor works with the reflection plate so that both the surface of the Ribbon Sensor and the reflection plate have to be parallel to each other.
