Sp4000 Scanner - Ricoh BE-C1 D046 Field Service Manual

Displays the values for Vsp/Vsg (0.0V to 5.0V)
1 Vsg Measured reflection of bare drum surface.
2 Vsp Measured reflection from ID sensor pattern.
ID Sensor Pattern Interval
3920
Determines the intervals between ID sensor readings of the ID sensor pattern.
1 Job End
[20 to 1000/100/10 cm]
This SP sets the distance between creation and reading of the ID sensor patterns. The default
setting (100) creates the ID sensor pattern for the next reading if the previous copy was longer
than 100 cm (4 in.).
2 During Job On/Off
This SP determines whether ID sensor patterns are created and read during jobs.
[0 to 1/1/1]
1: On. ID sensor patterns are created and read during the job at prescribed intervals so the
Vsp/Vsg readings are updated for more accurate toner supply control. (The interval is
prescribed by SP3020-3 below.)
0: Off. No ID sensor patterns are created and read during the job. The machine uses the last
Vsp/Vsg reading of the previous job for toner supply control.
3 During Job
[20 to 200/100/10 cm]
This SP determines the interval for creation and reading of the ID sensor pattern done for toner
supply control during a job. This setting is ignored if SP3920-2 above is switched off.
