4. Place a sheet of A4 or LTR blank paper (paper recommended by Canon) on the Platen Glass of the reader again, andexecute• COPIER > FUNCTION > CCD > DF-WLVL3 (White level adj in book mode (B&W))5. Place the same blank paper on the ADF again, and execute• COPIER > FUNCTION > CCD > DF-WLVL4 (White level adj in ADF mode (B&W))6. If the operation was successful, write the setting value on the service label.7. Whether the operation was successful or failed is not shown on the UI, so perform the following procedure to judge ifthe operation is successful or not.• COPIER > ADJUST > CCD > DFTAR-R (Adjustment of shading target value (R) at ADF reading)• COPIER > ADJUST > CCD > DFTAR-G (Adjustment of shading target value (G) at ADF reading)• COPIER > ADJUST > CCD > DFTAR-B (Adjustment of shading target value (B) at ADF reading)Check the foregoing values, and if all the values remain the same with those you entered, the operation result is judgedto be "failed".8. If the operation result is "failed", turn OFF and then ON 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) at ADF reading)If the value remains the same as the value you entered, the operation result is judged to be "failed".10. If the operation result is "failed", turn OFF and then ON 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.4. Copyboard geometric adjustmentEnter the values shown on the label that comes with the part in the following service mode items.• COPIER > ADJUST > ADJ-XY > ADJ-X (Adj of img pstn in book mode: vert scan)• COPIER > ADJUST > ADJ-XY > ADJ-Y (Adj of img pstn in book mode: (horizontal scanning direction)• COPIER > ADJUST > ADJ-XY > ADJ-X-MG (Fine adj image ratio: vertical scanning)Enter the values in the foregoing service mode.5. ADF geometric adjustment1. On an image copied using the ADF, check the non-image width in the X and Y directions and the expansion/contractionin the X direction.In the case of E353MGMH, perform 2-sided original reading from the ADF.If adjustment is needed, enter necessary adjustment values in the following service mode:• COPIER > ADJUST > ADJ-XY > ADJ-Y-DF (Adj img pstn in ADF mode:horz scan)• FEEDER > ADJUST > DOCST (Fine adjustment of VSYNC timing at ADF reading [front side])• FEEDER > ADJUST > DOCST2 (Fine adjustment of VSYNC timing at ADF reading [back side])• FEEDER > ADJUST > LA-SPD (Fine adjustment of magnification ratio in vertical scanning direction at ADF streamreading [front side])• FEEDER > ADJUST > LA-SPD2 (Fine adjustment of magnification ratio in vertical scanning direction at ADF streamreading [back side])2. If you enter adjustment values, write the final values on the service label.■ After Replacing the Scoopup Sheet Holder1. Automatic adjustment of the stream reading position1. Entering a provisional valueSet the value of• COPIER > ADJUST > ADJ-XY > STRD-POS (Adjustment of reading position at ADF stream reading)to "-20".2. Automatic adjustment of the stream reading positionExecute• COPIER > FUNCTION > INSTALL > STRD-POS (Scan position auto adj in ADF mode)If the operation was successful, write the value of STRD-POS on the service label.5.
