This function is displayed only if the settings are made available by your local authorized Canon dealer. Even if this function is displayed, do not allow anyone to
change the settings except for the system manager. For more information on changing the settings, contact your local authorized Canon dealer.
1) Select Settings/Registration > Adjustment/Maintenance > Adjust Image Quality > Correct White Gap > adjust the adjustment value to "1" or "2" by pressing "-
" or "+" > press OK.
- "1" and "2": Select to eliminate the white gap. If "1" is selected as a setting value, you can eliminate the white gap more effective than "2". However, the image
tends to have a jagged appearance or the density of the image tends to be light.
- "3": This is the default setting. Select when you want to leave the original image as it is.
- "4": Do not select normally. If you select this setting value, contact your local authorized Canon dealer.
[Reference]
If you select "1" or "2" as a setting value, the image may have a jagged appearance, lighter density, or stripe pattern. If these print results may occur, you may be
able to eliminate the white gap by specifying the dither settings (see "Dither Settings"), instead of specifying the white gap correction. For more information, contact
your local authorized Canon dealer.
- Select Settings/Registration > Adjustment/Maintenance > Adjust Image Quality > Dither Settings > select the value for "Gradation" and "Resolution" > press "OK"
2) Implement the automatic gradation adjustment (full adjustment).

tion with paper for the test print > press OK.

The following procedures are required when using the Duplex Color Image Reader Unit-H1 as an automatic gradation adjustment method. When using the Auto
Gradation Sensor-A1, you do not need to scan test pages. When you press "Start Printing", the machine prints test pages and perform full adjustment automatically.
