Black is selected as the Color setting in the printer driver.

Change this setting to Color.

The color setting in the application you are using is not appropriate for color printing.

Make sure that the settings in your application are appropriate for color printing.

One of the imaging cartridges may be the end of its service life but printing was continued by pressing  Start/Stop button.

If a Replace Toner uuuu error occurs, replace the imaging cartridge without pressing the  Start/Stop button. See Imaging Cartridge.

Printer driver default settings and color tables vary by printer model.

Set the Gamma setting to 1.8 in the More Settings dialog box in the printer driver, then print again. If you still do not get the printouts you expect, adjust the color using the slide bar for each color. For details about the More Settings dialog box, see the printer driver’s online help.

Printed colors do not exactly match the colors on your monitor, since printers and monitors use different color systems: monitors use RGB (red, green, and blue), while printers typically use CMYK (cyan, magenta, yellow, and black).

Although it is difficult to match colors perfectly, selecting the printer driver’s ICM setting (for Windows XP, XP x64, Me, 98, 2000, Server 2003, or Server 2003 x64) or ColorSync setting (for Macintosh) can improve color matching between different devices. For details, see the printer driver’s online help.

For Macintosh, the System Profile setting is not in use.

To apply ColorSync properly, your input device and the application must support ColorSync, and a System Profile must be used for your monitor.

PhotoEnhance may be selected in the printer driver.

The PhotoEnhance feature corrects the contrast and brightness of the original image data, and so may not be suitable for printing vivid images.
