Adjusting Image Quality

The Xerox Nuvera user interface contains a set of Image Quality adjustment tools for Copy, Scan to File and Print jobs. Using these controls, you can make adjustments to images containing text, photographic images, halftoned images, as well as documents with mixed image types. This is useful if the original document is less than perfect; i.e., text/images are too light or too dark.

To learn more about these capabilities, explore the links at the left.


NOTE: If the Enhanced Line Screen license is enabled, the system supports jobs with 85, 106, 125, 134 and 156 lpi halftone screens. If this license is not enabled, only 125 lpi is supported.

To adjust image quality on scanned jobs

  1. At the Xerox Nuvera user interface, click on Copy (or Scan to File), then click on the Image Quality tab.
  2. Choose the Original Type of the image to be copied. Click on the Original Type button, then click on the Rendering Options Setup button. Choose any options according to the condition and type of the original document.
  3. Click on the Basic tab, then use the Darken/Lighten control to make small corrective adjustments.
  4. Click on the Image Quality tab, then click on the Image Adjustments button. Use the Contrast, Sharpness and Background Suppression controls to make small corrective adjustments.

TIP: If you copy/scan a great number of the same type of original documents, you can set custom image quality defaults. For example, if the majority of your copying/scanning is of dark photographic content, the system defaults can be set to accommodate this, saving you job programming time. To set up your system defaults to match your original input, contact your System Administrator.

To adjust image quality on print jobs

  1. Open the Print from File Manager and locate and select the job.
  2. Select the Image Quality tab.
  3. From the Mode pull down menu, select the printer emulation setting. The DocuTech 135 setting prints output that is similar in appearance to that of the DT135 printer.
  4. Use the Print Darkness control to make small corrective adjustments in increasing or decreasing darkness. All pixels in the image are moved either towards black or white. The values closest to 0 are intended for small adjustments to the darkness of text and pictures. The darkness +/-3 settings will make a noticeable difference on text but not recommended for most pictorials.
  5. Select a Resolution. Since resolutions vary from printer to printer, use this option to achieve better performance for jobs that were saved at 300 dpi.
  6. Set Print Quality. The Toner Saver selection uses less toner and is more economical than the full quality setting of Normal. It is useful for scatter removal without causing a light solid image on the page. You may want to use the Normal setting when printing proof documents.
  7. To select a halftone, open Job Manager, locate and open the job. From either the Print Properties window or the Job Properties window, select a Halftone. This allows you to adjust the pattern of dots or lines of varying sizes applied to an image of varying tones, or same sized dots applied to a tint of color.

NOTE: If the Enhanced Line Screen license is not enabled, the Halftone selection is not available since there is only one halftone (125 lpi) offered.

Stroke Thickening (increasing the weight or width of a character)

  1. Open the Job Manager and select and open the job.
  2. Select the Image Quality tab.
  3. From the Job Properties window and the Stroke Thickening field, adjust this setting to control the thickness of fine lines created by the PostScript stroke command.

About Toner Saver

The Toner Saver Print Quality selection is intended to save toner costs, similar to draft mode.


NOTE: Toner Saver is designed to save toner, and can produce poor image quality and undesirable, light, or washed-out prints.
