HP Photosmart C6280 All-in-One Printer - Manual (Page 126)

Solution: If the paper is too close to the print head during printing, the ink might be
smeared. This can happen if the paper is raised, wrinkled, or very thick, such as a
mailing envelope. Make sure the paper lays flat in the input tray and is not wrinkled.
Ink is not filling the text or graphics completely
Cause: The Paper Type setting is incorrect.
Solution: Change the Paper Type setting to match the type of paper loaded in the
input tray.
For more information, see:
• “Set the copy paper type” on page 87
• “Set the paper type for printing” on page 47
Cause: The print quality setting on the HP All-in-One is set too low.
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.

“Information on paper” on page 111
Cause: The print head needs to be cleaned.
Solution: Clean the print head, and then print a self-test report. Check the color

perform a printer alignment.
