Troubleshooting Print-Quality Problems in the Printer
If you have print-quality problems when printing a Demo Page or the Configuration Report from the
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 288.
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.
