Color Printing Problems
Cannot print in color
The printout color differs when printed from different printers
The color looks different from what you see on the computer screen
Cause What to do
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 N Start/Stop button.
If a Replace Toner uuuu error occurs, replace the 
imaging cartridge without pressing the N Start/Stop 
button. See "Imaging Cartridge" on page 228.
Cause What to do
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.
Cause What to do
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.
