Fig.5 Measurement Condition
1. Apply V
2. In order to stabilize output voltage measure 3. to 5. on the LED lighting condition shown in Fig.3 for example.
3. Measure the output voltage V
4. Attach the color toner and measure the output voltage at V
5. Attach the black toner and measure the output voltage at V
6. After the measurement, set I
