<Adjust Image Quality>

This section describes how to adjust image quality for copying and printing.

<Auto Adjust Gradation>

(Settings/Registration)

If the gradation of the printing is significantly different from the original document, this correction adjusts the printing so that it more closely matches the original document. Adjusting Gradation


It is recommended that you select <Full Adjust> when performing an automatic gradation adjustment. Select <Quick Adjust> for a quick, but less complete adjustment between regular full adjustment recalibrations. You can use the following paper sizes/types with <Full Adjust>. Size: A3, A4, 11" x 17", LTR Type: Plain, Heavy 1, Heavy 2 to 7


Test pages are not counted as part of the copy or print total page counts.

<Auto Correct Color Tone>

(Settings/Registration)

If the color of the printing is significantly different from the original document, this correction adjusts the printing so that it more closely matches the original document. Adjusting Color Tone

<Register Correction Pattern>

(Settings/Registration)

To create an adjustment standard of your choice for color adjustment, register an adjustment standard. Adjusting Color Tone

<Job Type to Apply To>

(Settings/Registration)

Set whether to perform color adjustment for copy jobs and print jobs.

<Correct Density>

(Settings/Registration)

If the density of the printing is significantly different from the original document, this adjusts the scan density to be closer to the original. Adjusting Density

<Correct Shading>

(Settings/Registration)

If the image areas of the printing have uneven density, this correction adjusts the printing so that the density is even. Correcting Uneven Density

<Auto Correct Color Mismatch>

(Settings/Registration)

If the colors of printing run or blur, color mismatch (color misregistration) may have occurred. This correction adjusts the printing so that color mismatch does not occur. Correcting Color Mismatch

<Full Color Printing Vividness Settings>

(Settings/Registration)

This setting enables you to make colors more saturated when performing color printing. Making Colors More Vivid


This setting is only effective for copy jobs and print jobs of documents (scanned data) stored in mail boxes. Changes in settings are effective after performing <Apply Setting Changes>.

<Fine Adjust Zoom>

(Settings/Registration)

If the size of the image copied is significantly different from the original document, fine adjustment is performed so that the printing more closely matches the size of the original document. Adjusting Image Size

<Dither Pattern Settings>

(Settings/Registration)

Set the dither pattern to produce printed images with smoother gradation and edges. Setting the Dither Pattern

<Color Balance>

(Settings/Registration)

This setting enables you to perform fine adjustment to the density and strength of the color balance. Adjusting Color Balance

<Adjust Drum Temperature>

(Settings/Registration)

In a high-temperature or high-humidity environment, partial distortions, or thin white lines may appear on printed images.You can prevent this problem by adjusting the photoconductor drum temperature.


Be sure to contact your local authorized Canon dealer before adjusting the photoconductor drum temperature. Increasing the drum temperature may cause the developer to deteriorate.

<Special Smoothing>

(Settings/Registration)

This setting smoothes jagged outlines of dark colour characters, lines, figures, photos, images, and gradations by correcting colour displacement that occurs in the output.


Make sure to set this setting to <Off> when you do not perform the correction. Depending on the types of originals, this function may cause other colour displacement or jagged outlines.

<Gradation Adjustment During Printing>

(Settings/Registration)

To maintain the stability of gradation, density, and colour, the machine performs the density adjustment internally during printing. The sensor detects the density of a patch, which is created on the Intermediate Transfer Belt every several sheets of paper is printed, to perform the density adjustment. You can increase the frequency of the density adjustment to maintain more stable image quality, if necessary.


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. If you increase the frequency of the adjustment, image quality becomes more stable but the adjustment time may increase and the print speed may be adversely affected.
