Poor print quality is seen in all images printed in color and black halftones.
There are a few possible causes for a poor quality color and black halftone in 4800 CQ and 1200 dpi.
- The paper type, paper weight, or paper texture settings do not match media being used. Input the correct media settings.
- The media is not supported. Consult the User's Guide and Card Stock & Label Guide for supported media specifications.
- Calibration failure. Manually initiate a calibration following the steps below:
– For C792: Settings > Quality > Color Adjust.
– For X792: Printer Settings > Quality > Color Adjust.
- Extreme black margin settings can cause color calibration to fail. Fix printer's Registration values (in Diagnostics menu). Follow Step 3 to recalibrate the printer.
- The toner cartridge is running low on toner or has been damaged. Try a new Lexmark cartridge.
