(4) Drum Master Sensor
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 - 005.
Description
The drum master sensor is located at a fixed
distance relative to the drum. By means of reflected
light, this sensor senses master setting errors.
When a master setting error occurs,
"MASTER SET
ERROR"
is displayed.
While the master is not set to the drum, printing
will not start even if the
(PRINT)
key is
pressed. Instead,
“CANNOT PRINT”
is displayed.
