[Operation]
1) Initial display
30-01 P-SENSOR
[Function]
When this simulation is executed, the current set value is displayed. When [ENTER]/[START]
key is pressed, the mirror base unit moves to the RSPF scan position to acquire the OC cover
float detection level.
When the mirror base unit returns to the home position, the acquired value is displayed.
If the adjustment is NG, the following message is displayed.
The LCD indicates "ERR."
Note that, this simulation must be executed with the OC cover closed.
∗ If the value is 0, float detection is not performed in normal jobs.
[Operation]
1) Initial display
41-06 OC FLOAT LEVEL
0
2) [ENTER]/[START] key
41-06 OC FLOAT LEVEL
EXECUTING...
[Function]
For the number of pixels between black markers on the SPF/RSFP scanning position saved in
"41-06: (OC cover float detection level adjustment)", if the number of pixels between the mark-
ers when processing float detection is less than the number of pixels set with this simulation, it
is judged as the float error.
When the set value of this simulation is "0," no float error occurs.
When this simulation is executed, the current set value is displayed.
Enter the adjustment value with [Numeric] key and press [START] key. The setting is saved and
the display is shifted to the sub code input standby menu.
Setting range: 0 – 99 (Copes with margin 0 – 99 pixels.)
Default: 30 (30 pixels)
[Operation]
The operation is similar to simulation 9-04.
