on the DADF.
Use Case
- When replacing the Copyboard Glass
- When replacing the Scanner Unit
- When replacing the Reader Controller PCB/clearing RAM data
Adj/Set/Operate Method
1) Set paper on the DADF.

Supplement/Memo
- In the case of DADF (reverse model)
The Scanner Unit (for front side) calculates the white level correction coefficient based on the
luminance at copyboard reading detected with DF-WLVL1 and the luminance at stream reading
detected with DF-WLVL2.
- In the case of DADF (1-path model)
The Scanner Unit (for front side) calculates the white level correction coefficient based on the
luminance at copyboard reading detected with DF-WLVL1, the luminance at stream reading
detected with DF-WLVL2, and the luminance at stream reading that the Scanner Unit (for back
side) detected with DF-WLVL2.
