Description
The master top sensor is located at a fixed distance
relative to the master. By means of reflected light,
this sensor senses the presence of the master on the
master travel path.
If the photointerrupting condition (master not
present) is not obtained during platemaking,
"MASTER SET ERROR"
is displayed.
