Solving Image Quality Problems

The Xerox Nuvera is capable of reproducing and generating high-quality images.

However, image defects may occur. These image quality problems are usually attributed to a defective original, or the user applying too much, too little, or the wrong type of image quality control.

Image quality and system maintenance

Image defects can also occur because the Xerox Nuvera is in need of maintenance. The condition of the photoreceptor belt, transfer blade and heat roller can affect the amount of toner transferred onto the paper.

Solving dark or light image problems

With the Image Quality Tab in the Printer Manager, you can globally set the darkness and resolution levels for system supported file types. Check the Image Quality tab settings if you are having image quality problems on a consistent basis (for example, your entire job is either too light or too dark).

If you are using the Xerox Nuvera 288 Digital Perfecting System, the machine typically ensures that the print darkness between the print engines is equal and balanced. However, if you notice light or dark image quality differences between side 1 and side 2 of the print job, check the dC965 user diagnostic routine before contacting Service

TIP: Before running any jobs, click [Printer Manager: Image Quality] to quickly determine what global machine darkness and resolution settings are currently configured.

NOTE: See your System Administrator to change the darkness and/or resolution settings on the Image Quality tab. If you are using the Xerox Nuvera 288 Digital Perfecting System and side 1 of your job is either lighter or darker than side 2, refer to the image quality diagnostic routine, dC965, for more information.

TIP: If you have programmed and run a job, and received unexpected results, ensure that the system-wide settings are all set back to their defaults by clicking <Clear All> or <Reset> in the user interface. Then proceed to do the job programming pertinent to your job.
