Ricoh MP C2504 - Electrified Potential; Development Bias, Vref Correction

Electrified Potential / Development Bias, Vref Correction
Electrified Potential/ Development Bias and Vref Correction are done with the following method.
The operation time differs depending on the line speed.
1. Adjusting the ID sensor Vsg
The machine adjusts the LED strength of the ID sensor so that the value of Vsg (the charge which is
detected from the background on the Transfer Belt) will be in the range of 4.0V ±0.5V. When Vsg
is detected as not within the target range three times, SC370 (ID sensor error) will be detected.
