Colors are printing as black and white

Check the printer driver settings

For Windows, the Print In Grayscale check box is probably selected. From your software application, open the Printer Properties dialog box. Click the Color tab and make sure Print in Grayscale is not selected.

For Macintosh, open the Print dialog box and from the Image panel, make sure that Grayscale is not selected.

If you are printing with only the black or photo print cartridge, the printout will be printed in grayscale. See Single-cartridge printing mode.

Wrong colors are printing

Check the printer driver settings

For Windows, the Print In Grayscale check box might be selected. From your software application, open the Printer Properties dialog box. Click the Color tab and make sure Print in Grayscale is not selected.

For Macintosh, open the Print dialog box and from the Image panel, make sure that Grayscale is not selected.

For Windows, try adjusting the Saturation, Brightness and Color Tone from the Color tab in the printer driver. For Macintosh, adjust these settings from the Color Panel in the Print dialog box.

Check the print cartridges

When colors are completely wrong, the printer might have run out of one or more colors of ink. Check the print cartridge LEDs to make sure they are not on (see LED Reference). You can also check the status of the print cartridges from the Printer Status tab in the Toolbox. Replace any low or empty print cartridges. For instructions, see Replacing the print cartridges.

If you are printing with only one print cartridge, see Single-cartridge printing mode.

If you have the tri-color and photo print cartridges installed, and the color does not print out as expected or there is a color tinge in gray shades, try calibrating the color. For instructions, see Calibrating color.

Whenever print quality noticeably decreases, try cleaning the print cartridges. For instructions, see Cleaning the print cartridges.
