Material end sensor
The material end sensor recognises when
no more material is there and thus protects
the printhead from unnecessary wear. The
error is displayed, and the machine stops.
The light barrier for sensing the end of ma-
terial [141 circled] is located in the internal
material guide of the machine. The light
barrier sensor is attached to the guide and
can only be replaced as a complete unit.

For details on testing the light barrier sen-
sor: see topic section
