HP Photosmart C4380 All-in-One Printer - Manual (Page 115)

Use OpenType or TrueType fonts to ensure that the HP All-in-One is able to print
smooth fonts. When selecting a font, look for the TrueType or OpenType icon.
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. Print the
image using six-ink printing. To do so, install the photo print cartridge in place of the
black print cartridge. With the photo print cartridge and the tri-color print cartridge
installed, you have a six-ink system, which provides enhanced quality photos.

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.

the HP All-in-One.
