<Adjust Image Quality>

This section describes how to adjust image quality for printing.

<POP Print Calibration>

<Set>

Use this function to correct color mismatch and hue difference if they occur in POP printing.


Perform <Full Calibration>, and then execute <POP Print Calibration>.

<Auto POP Calibration>

<Set>

You can change the type of calibration that will be performed automatically. In addition to ordinary calibration, a calibration to correct hue mismatch that has occurred in POP printing. When [POP Printing Optimization] is configured on the printer driver, always specifying <On> is recommended. For more information on [POP Printing Optimization], see the manuals for the relevant drivers on the online manual website.


When you specify <On>, calibration will take longer time. Further, the lifetime of toner cartridges may be affected. When [POP Printing Optimization] is configured, it is recommended that you also configure the following items. <Toner Cartridge Replacement Notif. Mode>

<Full Calibration>

<Set>

Use this function to correct color mismatch and hue difference.

<Settings for Auto Full Calibration>

<Set>

The machine performs automatic adjustment (calibration) in order to prevent color misregistration and ensure that the original color intensity is correctly reproduced. You can set the timing and frequency for performing calibration. Correcting Color Mismatch and Hues

<Adjust Print Position>

<Set>

You can adjust the print position when printing is lopsided or protruding from the print range. Adjusting the Print Position

<Adjust Toner Volume Used for Color Print>

<Set>

By adjusting the amount of toner used when color printing, you may be able to reduce problems such as streaks and irregularities. Reducing Toner Used When Color Printing

<Waterdrop Pattern Prevention Mode>

<Set>

When you perform 2-sided printing after the machine is left unused for a long time, void may occur in printed images. In this case, setting this item may solve the problem. The improvement effect is stronger with <Mode 2> than with <Mode 1>.


In the case of 2-sided printing with this item set to other than <Off>, it may take longer until printing starts.

<Reduce Waterdrop Pattern>

<Set>

If print density of printed images is uneven in a way that the print looks like a water drops pattern, setting this item to <On> may solve the problem.


If you select <On>, print quality may be affected.

<Correct Background Density>

<Set>

Use this setting when the entire surface of the paper is dark when printing in a high humidity environment.

<Correct Color Shift>

<Set>

If color mismatch occurs, setting this item to <On> may solve the problem.


If you select <On>, the print speed may be slower.

<Reduce Ghosting 2>

<Set>

If continuous printing involves generation of ghost images, setting this item to other than <Off> may solve the problem. The improvement effect is stronger with <Mode 2> than <Mode 1>.


Selecting <Mode 1> or <Mode 2> may result in uneven print density.

<Reduce Ghosting 3>

<Set>

If the printout reveals a ghost of an image in the same page, setting this item to <On> may solve the problem.


Setting to <On> may result in uneven print.

<Auto Detect B&W/Color Original>

<Set>

When printing data including both black and white data and color data, you can specify whether to give priority to higher printing speed or lower frequency of CMY toner cartridge usage.


If you select <Mode 2>, the printing speed may be slower.

<Reduce Margin Stain>

<Set>

If smudge marks appear in the margin on the bottom edge of printouts, changing the setting may solve the problem.


In the case of continuous printing with <Mode 1> or <Mode 2> specified, printing a larger number of pages than a certain specific number triggers automatic cleaning, resulting in a slower printing speed. If you select <Mode 2>, cleaning will be performed more frequently than with <Mode 1>.

<Correct Black & White Density>

<Set>

When <Color Mode> under <Custom Settings> (Custom Settings) or <Color Mode> under <Access Stored Files Settings> (<Access Files>) is set to <Auto (Color/B&W)> or <Black & White>, uneven print density may result or horizontal streaks may appear in the printout. In this case, setting <Mode 1> or <Mode 2> may solve the problem.


With <Mode 1> or <Mode 2> specified, the CMYK toners are consumed even in black and white printing depending on the paper type used. Further, the print speed may be slower. With <Off> specified, black and white printing may result in uneven print density. The operation is the same for both <Mode 1> and <Mode 2>.

<Correct Void for Consecutive Printing>

<Set>

Continuous printing may result in uneven print density. In this case, setting this item to <On> may solve the problem.

<POP Print Settings>

<Set>

If the quality of the printout is not acceptable when printing with [POP Printing Optimization] configured on the printer driver, specifying <Mode 2> is recommended. It will result in POP prints with a more vivid color tone. For more information on [POP Printing Optimization], see the manuals for the relevant drivers on the online manual website.


If you select <Off>, normal printing will be performed even if [POP Printing Optimization] is set in the printer driver. If you select <Mode 2>, the print speed will be slower. When [POP Printing Optimization] is configured, it is recommended that you also configure the following items. <Toner Cartridge Replacement Notif.
