Reflection light amount
The larger the reflection light amount is, the
smaller the output voltage is. The smaller the light
amount is, the larger the output voltage is.
The value is checked with the HELP 05.
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 intensity of the reflected
light does not reach the "black" level (no master) a
single time during platemaking,
"MASTER
SETTING ERROR"
is displayed.
