1. Master Setting Error Detection
Operation
In platemaking, the end mark sensor uses amount of reflected light to detect presence or absence of a master
on the transfer path. Then the following displays and operations are performed:
Timing
2
While platemaking is being processed, the reflection light amount does not turn to be in a white level.
(Master detection sensor)
2
When completing platemaking, reflected light amount received by the master top sensor is at the white level
(master present).
Timing
When it is considered that the end mark is read under the following conditions,
"NO MASTER"
is displayed.
1.
While the master is rolling up to the drum during platemaking, the following is checked.
2.
When the master passes under the end mark sensor, the amount of reflected light is read.
3.
If the following conditions are met, it is considered as master end.
150 or more detected continuously.
2. Master End Detection
Operation
The end mark is printed on the area about 1 m from the end of the master.
2
When the end mark is detected,
"NO MASTER"
is displayed.
2
When
"NO MASTER"
is displayed, plate-making is not performed next.
(The display is not cleared by turning the power off.)
R8S02026e
2
When a master setting error is detected,
"MASTER SET ERROR"
is displayed and printing is not
processed.
2
"MASTER SET ERROR"
is only cleared by opening and closing the master cover.
(It is not cleared by turning the power off.)
2
Printing is not performed but platemaking is only performed when the display is cleared after "MAS-
TER ERROR" is displayed. (Because the master is not attached to the drum.)
