1. White level adjustment
• COPIER > FUNCTION > CCD > DF-WLVL1 (White level adjustment [copyboard
scanning])
• COPIER > FUNCTION > CCD > DF-WLVL3 (White level adjustment BW [copyboard
scanning])
Then, set a blank paper on the DF, and execute the following service mode.
• COPIER > FUNCTION > CCD > DF-WLVL2 (White level adjustment [DF scanning])
• COPIER > FUNCTION > CCD > DF-WLVL4 (White level adjustment BW [DF
scanning])
If it fails, turn OFF/ON the power and execute the operation again.
2. Checking the setting value
• COPIER> ADJUST> CCD> DFTAR-R (RED shading target value when using DF)
• COPIER> ADJUST> CCD> DFTAR-G (GREEN shading target value when using DF)
• COPIER> ADJUST> CCD> DFTAR-B (BLUE shading target value when using DF)
• COPIER> ADJUST> CCD> DFTAR-BW (Monochrome shading target value when
using DF)
4) Execute the reading position adjustment with the following service mode.
• COPIER > ADJUST > ADJ-XY > ADJ-Y (Value adjustment for image reading start
position [vertical scanning direction] <X-axis direction>)
• COPIER > ADJUST > ADJ-XY > ADJ-Y-DF (Adjustment of surface horizontal scanning
position in FEEDER mode)
• COPIER > ADJUST > ADJ-XY > ADJ-X-MG (Fine-adjustment of optical motor speed)
5) Execute the original stop position and feed speed adjustment at stream reading.
