Troubleshooting Print-Quality Problems in the Printer

control panel, the problem is in the printer.
To find the source of the problem:
1. At the control panel, print the Troubleshooting Print-Quality Pages. For details, see Printing the
Troubleshooting Print Quality Pages on page 258.
2. If the prints are too light to see print details, verify the following:
− The printer is loaded with undamaged, dry supported paper.
− The toner levels of one or more of the toner cartridges is not too low.
3. If the pages are printed with a solid color, one or more of the drum cartridges could be defective.
Correct the problem before continuing.
4. If the colors of the pages do not match your expectations, run the control panel Print Calibration.
5. Compare the print-quality problems in your document to each of the examples in the
Troubleshooting Print-Quality Pages.
If you find a match in the Troubleshooting Print-Quality Pages, look in the Solutions column for the
action to take to resolve the problem.
