    Note:
    If a status sheet does not print correctly, your product may be damaged. Contact your dealer or a 
    qualified service representative.
    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.
    Cause What to do
    Printer driver default settings and color tables 
    vary by product 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 products and 
    monitors use different color systems: monitors 
    use RGB (red, green, and blue), while 
    products 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.
