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 single sided 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 ADF 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
5. ADF (front/back) geometric adjustment
1. On an image 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 needed, enter the following adjustment values.
• 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. If you enter adjustment values, write the final values on the service label.
