DF White Level (DF Shading Target) Adjustment

In the case of entering a provisional value

1. Change the values of the following service mode settings to 299.
   • COPIER > ADJUST > CCD > DFTAR-R
   • COPIER > ADJUST > CCD > DFTBK-R
   Change the values of the following service mode settings to 309.
   • COPIER > ADJUST > CCD > DFTAR-G
   • COPIER > ADJUST > CCD > DFTBK-G
   Change the values of the following service mode settings to 307.
   • COPIER > ADJUST > CCD > DFTAR-B
   • COPIER > ADJUST > CCD > DFTBK-B
   Change the values of the following service mode settings to 315.
   • COPIER > ADJUST > CCD > DFTAR-BW
   • COPIER > ADJUST > CCD > DFTBK-BW
2. Place an A4 or LTR size paper on the Copyboard Glass and execute the following service mode.
   • COPIER > FUNCTION > CCD > DF-WLVL1
3. Place an A4 or LTR size paper on the ADF and execute the following service mode.
   • COPIER > FUNCTION > CCD > DF-WLVL2
4. How to judge whether the operation was successful or failed
   Whether the operation was successful or failed is not shown on the UI, so perform the following procedure to judge if the operation was successful or failed.
   Check the following values, and if all the values remain the same as those you entered, the operation result is judged to be "failed".
   • COPIER > ADJUST > CCD > DFTBK-R
   • COPIER > ADJUST > CCD > DFTBK-G
   • COPIER > ADJUST > CCD > DFTBK-B
   • COPIER > ADJUST > CCD > DFTBK-BW
5. In the case of a failure, turn OFF and then ON the power, and execute the following service mode again.
   • COPIER > FUNCTION > CCD > DF-WLVL1
   • COPIER > FUNCTION > CCD > DF-WLVL2
6. If the operation was "successful", write the entered values on the service label.

ADF (Front/Back) Geometric Adjustment

In the case of manual adjustment

1. On an image duplex copied using the ADF, check the non-image width in the X and Y directions and the expansion/
   contraction in the X direction.
   If adjustment is necessary, adjust the values of the following service mode settings.
   • COPIER > ADJUST > ADJ-XY > ADJ-Y-DF
   • COPIER > ADJUST > ADJ-XY > ADJY-DF2
   • FEEDER > ADJUST > DOCST
   • FEEDER > ADJUST > DOCST2
   • FEEDER > ADJUST > LA-SPEED
   • FEEDER > ADJUST > LA-SPD2
2. Write the entered values on the service label.
