Ld Power Control - Ricoh MP C2504 Field Service Manual

• SP3-320-031/032/033 (Vsg Error Counter)
• SP3-320-013 (Vsg Upper Threshold)
• SP3-320-014 (Vsg Lower Threshold)
2. Agitating the Developer (5 seconds)
The machine agitates the developer and reads the TD sensor output.
• SP3-539-001 (Dev Agitating Time :Set)
3. Creating patterns, detecting the density
5 patterns are created on the transfer belt and detected by each ID sensor, with the Charge/
Development Bias adjusted for each pattern.
The ID sensor contains an LED [B] and two types of photo detector. The sensor detects the reflection
from the LED with the positive photo detector (REG) [A] and the diffusion photo detector (DIF) [C].
4. Determining Vtref from the Development Gamma
This decides the charge voltage and development bias
