HP C7280, C7250, C7288 manual Printout has a horizontal band of distortion near the bottom

The printout has a horizontal band of distortion near the bottom of the page

Cause: Your image has light blue, gray, or brown hues that print near the bottom of the page.

Solution: Load high-quality paper in the input tray and print the image with a high print quality setting, such as Best, Maximum dpi, or High Resolution. Always make sure the paper you are printing on is flat. For best results when printing images, use HP Premium Plus Photo Paper.

If the problem persists, use the software you installed with the HP All-in-One or another software application to rotate your image 180 degrees so that the light blue, gray, or brown hues in your image do not print at the bottom of the page.

Colors run into each other on the printout

Cause: The print or copy quality setting is set too high for the type of paper loaded in the HP All-in-One.

Solution: Check the quality setting. Use a lower quality setting to decrease the amount of ink used for printing or copying.

Cause: The paper type is not suitable for the HP All-in-One.

Solution: Use HP Premium Papers or any other paper type that is appropriate for the HP All-in-One.

Cause: You are printing on the wrong side of the paper.

Solution: Load paper with the side you want to print on facing down. For example, if you are loading glossy photo paper, load the paper with the glossy side down.
