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


LD Power Control

LD Control is set with SP3-600-002(Process Control/ Select ProCon: LD Control).

To use a fixed LD Power

Change the SP setting to [Fixed]. LD strength is fixed with SP2-221-001 to 004.

To control LD Power by Process Control (Default)

The LD power is determined by process control.

The LD strength is adjusted based on a table which is determined by the Development Bias Control and Vref Correction.
