3. How to judge whether the operation was successfulor failedWhether the operation was successful or failed isnot shown on the UI, so perform the followingprocedure to judge if the operation was successfulor failed.Check the value of• COPIER > ADJUST > ADJ-XY > STRD-POS(Adjustment of reading position at ADF streamreading)If it remains "-20", the operation is judged to be"failed".If the operation is judged to be "failed", turn OFFand then ON the power, and execute COPIER >FUNCTION > INSTALL > STRD-POS again.6. Adjust the white level in the following service mode,and write the final setting values on the service label.1. Enter the values in the following service modeitems respectively.• In COPIER > ADJUST > CCD > DFTAR-R, set"299".• In COPIER > ADJUST > CCD > DFTAR-G, set"309".• In COPIER > ADJUST > CCD > DFTAR-B, set"307" .• In COPIER > ADJUST > CCD > DFTAR-BW,set "315".2. Place a sheet of A4 or LTR blank paper (paperrecommended by Canon) on the Platen Glass ofthe reader, and execute• COPIER > FUNCTION > CCD > DF-WLVL1(White level adj in book mode (color))3. Place the same blank paper on the ADF, andexecute• COPIER > FUNCTION > CCD > DF-WLVL2(White level adj in ADF mode (color))4. Place a sheet of A4 or LTR blank paper (paperrecommended by Canon) on the Platen Glass ofthe reader again, and execute• COPIER > FUNCTION > CCD > DF-WLVL3(White level adj in book mode (B&W))5. Place the same blank paper on the ADF again, andexecute• COPIER > FUNCTION > CCD > DF-WLVL4(White level adj in ADF mode (B&W))6. If the operation was successful, write the settingvalue on the service label.7. Whether the operation was successful or failed isnot shown on the UI, so perform the followingprocedure to judge if the operation is successful ornot.• COPIER > ADJUST > CCD > DFTAR-R(Adjustment of shading target value (R) at ADFreading)• COPIER > ADJUST > CCD > DFTAR-G(Adjustment of shading target value (G) atADF reading)• COPIER > ADJUST > CCD > DFTAR-B(Adjustment of shading target value (B) at ADFreading)Check the foregoing values, and if all the valuesremain the same with those you entered, theoperation result is judged to be "failed".8. If the operation result is "failed", turn OFF and thenON the power, execute• COPIER > FUNCTION > CCD > DF-WLVL1(White level adj in book mode: color)and then execute• COPIER > FUNCTION > CCD > DF-WLVL2(White level adj in ADF mode: color)again.9. Checking the value of DFTAR-BWCheck the value of• COPIER > ADJUST > CCD > DFTAR-BW(Adjustment of shading target value (B&W) atADF reading)If the value remains the same as the value youentered, the operation result is judged to be"failed".10. If the operation result is "failed", turn OFF and thenON the power, execute• COPIER > FUNCTION > CCD > DF-WLVL3(White level adj in book mode (B&W))and then execute• COPIER > FUNCTION > CCD > DF-WLVL4(White level adj in ADF mode (B&W))again.7. Copyboard color displacement offset adjustmentEnter the value shown on the label that comes with thepart in the following service mode.Enter the values of 50-RG, 50-GB, 100-RG, and 100-GBshown on the replacement label in the following servicemode, and write the entered values on the service label.• COPIER > ADJUST > CCD > 50-RG (Colordisplacement (R and G lines) correction value inthe vertical scanning direction (50%))• COPIER > ADJUST > CCD > 50-GB (Colordisplacement (G and B lines) correction value in thevertical scanning direction (50%))• COPIER > ADJUST > CCD > 100-RG (Colordisplacement (R and G lines) correction value inthe vertical scanning direction (100%))• COPIER > ADJUST > CCD > 100-GB (Colordisplacement (G and B lines) correction value in thevertical scanning direction (100%))4.
