Print test page

Go here, and you can download a manual that has detailed instructions. Here are the instructions from the reference guide problem solver:

Running a printer operation check
If you are unable to determine the source of the problem, performing a printer operation check can help you determine whether the problem comes from the printer or the computer.
To print a printer operation check page, follow these steps.
Make sure both the printer and computer are turned off. Disconnect the cable from the printer's interface connector, then turn on the printer. Make sure that Letter size plain paper is loaded in the sheet feeder, the CD/DVD tray is not inserted into the printer, and the CD/DVD guide is closed. Hold down the paper button and press the power button to turn on the printer. Release only the power button. After the printer starts the operation check, release the paper button.
Compare the quality of the printed check page with the sample shown below. If there are no print quality problems, such as gaps or missing segments in the test lines, the printer itself is fine and the problem probably lies with the printer software settings, the application settings, the interface cable (be sure to use a shielded cable), or the computer itself.

If the check page does not print satisfactorily as shown below, there is a problem with the printer. For example, if any segment of the printed lines is missing, this could mean a clogged ink nozzle or a misaligned print head.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
