[Adjust Image Quality]

Perform image quality adjustments such as correcting the gradation or density in the printing results or scanned images.

* Values in red text indicate the default setting for each item.

Adjust the gradation if it is not reproduced correctly and the printing results differ significantly from the source data or original. Calibrating the Gradation

Adjust the density if the color density of the scanned data or printing results differs significantly from the source data or original. Correcting Density

Perform adjustment to make the density more even, if uneven shading occurs in the printing results. Correcting Uneven Density

For each paper source, adjust the print position to correct shifted characters or images. Adjusting the Print Position for Each Paper Source

If the size of the copied image differs slightly from that of the original, adjust the vertical and horizontal ratio in 0.1% increments to bring the size closer to that of the original. Adjusting the Print Size of the Copied Image

Select a dither pattern suitable for the image to be printed, to produce smoother gradations and contours in the printed image. Smoothing Curves and Gradations (Dither Pattern Settings)

Specify which is prioritized: Productivity and image quality. 
If you set [Productivity Priority] to [Mixed Paper Mode], it may keep the productivity from slowing down when you print with mixed paper types and sizes.
If you set to [Quality Priority], stable images can be formed even with high print rates, but productivity may decrease.

* Adjusting this setting may cause paper jams or poor image quality depending on the paper.

Fixing errors may occur if you continuously print high-density images on thick paper in a low temperature environment. This setting reduces the print speed to help prevent fixing errors. Preventing Fixing Errors in the Low-Temperature Environment (For 8100 Series Only)

When the temperature of the pressure roller rises excessively, uneven gloss may occur. Adjust the temperature rise level of the pressure roller to reduce the uneven gloss. Correcting Uneven Gloss (For 8100 Series Only)

In a high-temperature or high-humidity environment, partial distortions, or thin white lines may appear on printed images. Adjust the photoconductor drum temperature to improve the problem.

Set whether to correct color mismatch in the direction parallel to the feed direction, and whether to smoothly print text, diagrams, and images.

* Select [Off] if you do not want to perform correction. Depending on the original, new color mismatch or roughness may occur.

To maintain the stability of gradation and density, 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.
