5. 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.
• COPIER > ADJUST > CCD > DFTAR-R
• COPIER > ADJUST > CCD > DFTAR-G
• COPIER > ADJUST > CCD > DFTAR-B
• COPIER > ADJUST > CCD > DFTAR-BW
Check the foregoing values, and if all the values remain the same as those you entered, the operation result is judged
to be "failed".
6. In the case of a failure, turn OFF and then ON the power, and execute the following service mode items in sequence.
Place a sheet of A4 or LTR blank paper (paper recommended by Canon) on the Copyboard Glass of the reader and
execute the service mode.
• COPIER > FUNCTION > CCD > DF-WLVL1
Place the same blank paper on the ADF and execute the service mode.
• COPIER > FUNCTION > CCD > DF-WLVL2
7. In the case of the duplex scanning ADF model, check the following:
• COPIER > ADJUST > CCD > DFTBK-R
• COPIER > ADJUST > CCD > DFTBK-G
• COPIER > ADJUST > CCD > DFTBK-B
• COPIER > ADJUST > CCD > DFTBK-BW
If all the values remain the same as those you entered, the operation result is judged to be "failed".
In the case of the single sided scanning model, the operation result is judged to be OK even if this value does not
change.
8. In the case of a failure, turn OFF and then ON the power, and execute the following service mode items again.
• COPIER > FUNCTION > CCD > DF-WLVL1
• COPIER > FUNCTION > CCD > DF-WLVL2
9. Copyboard geometric adjustment
Enter the values shown on the label that comes with the part in the following service mode items.
100-RG
• COPIER > ADJUST > CCD > 50-RG
• COPIER > ADJUST > CCD > 100-RG
100-GB
• COPIER > ADJUST > CCD > 50-GB
• COPIER > ADJUST > CCD > 100-GB
Write the entered values on the service label.
To reduce the number of label items, the values of 100-xx and 50-xx are the same.
10. DF white level (DF shading target) adjustment
1. Enter the values in the following service mode items respectively, and then adjust the white level
• Set the value of COPIER > ADJUST > CCD > DFTAR-R to 299.
• Set the value of COPIER > ADJUST > CCD > DFTAR-G to 309.
• Set the value of COPIER > ADJUST > CCD > DFTAR-B to 307.
• Set the value of COPIER > ADJUST > CCD > DFTAR-BW to 315.
In the case of the duplex scanning ADF model, also change the following settings.
• Set the value of COPIER > ADJUST > CCD > DFTBK-R to 299.
• Set the value of COPIER > ADJUST > CCD > DFTBK-G to 309.
• Set the value of COPIER > ADJUST > CCD > DFTBK-B to 307.
• Set the value of COPIER > ADJUST > CCD > DFTBK-BW to 315.
2. Place a sheet of A4 or LTR blank paper (paper recommended by Canon) on the Copyboard Glass of the reader and
execute the following service mode.
• COPIER > FUNCTION > CCD > DF-WLVL1
3. Place the same blank paper on the ADF and execute the following service mode.
• COPIER > FUNCTION > CCD > DF-WLVL2
4. If the operation was successful, write the setting value on the service label.
