    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 
    NStart/Stop button.If a Replace Toner uuuu error occurs, replace the imaging 
    cartridge without pressing the NStart/Stop button. See 
    “Imaging Cartridge” on page 202.
    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) 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.

    because of insufficient memory, and the printer 
    lowers the quality automatically so that the printer 
    can continue printing.Check to see if the printout is acceptable. If not, add more 
    memory for a permanent solution or lower print quality 
    temporarily in the printer driver.

    Correcting USB Problems
    If you are having difficulty using printer with a USB connection, see if your problem is listed 
    below, and take any recommended actions.
    USB connections
    USB cables or connections can sometimes be the source of USB problems. Try one or both of these 
    solution.
    ❏For best results, you should connect the printer directly to the computer’s USB port. If you must 
    use multiple USB hubs, we recommend that you connect the printer to the first-tier hub.
    Windows operating system
    Your computer must be a model pre-installed with Windows Vista, Vista x64, XP, XP x64, 2000, 
    Server 2003, or Server 2003 x64, or a model that was pre-installed with Windows 2000, Server 2003, 
    or Server 2003 x64, and upgraded to Windows Vista, Vista x64, XP, or XP x64. You may not be able 
    to install or run the USB printer driver on a computer that does not meet these specifications or that 
    is not equipped with a built-in USB port.
    For details about your computer, contact your dealer.
    Printer software installation
    Incorrect or incomplete software installation can lead to USB problems. Take note of the following 
    and perform the recommended checks to ensure proper installation.
    Checking printer software installation
    When using Windows Vista, Vista x64, XP, XP x64, 2000, Server 2003, or Server 2003 x64, you must 
    follow the steps in the Setup Guide packed with the printer to install the printer software. 
    Otherwise, Microsoft’s Universal driver may be installed instead. To check if the Universal driver 
    has been installed, follow the steps below.
    1. Open the Printers folder, then right-click the icon of your printer.
    2. Click Printing Preferences on the shortcut menu that appears, then right-click anywhere in 
    the driver.

    Troubleshooting249
    If About is displayed in the shortcut menu that appears, click it. If a message box with the 
    words “Unidrv Printer Driver” appears, you must reinstall the printer software as described in 
    the Setup Guide. If About is not displayed, the printer software has been installed correctly.
    Note:
    For Windows 2000, if the Digital Signature Not Found dialog box appears during the installation process, 
    click Yes. If you click No, you will have to install the printer software again.
    For Windows Vista, Vista x64, XP, XP x64, Server 2003, or Server 2003 x64, if the Software Installation 
    dialog box appears during the installation process, click Continue Anyway. If you click STOP 
    Installation, you will have to install the printer software again.
    Status and Error Messages
    You can see the printer’s status and error messages on the LCD panel. For more information, see 
    “Status and Error Messages” on page 171.
    Canceling Printing
     You can cancel printing from your computer by using the printer driver or from the printer’s 
    control panel.
    To cancel a print job before it is sent from your computer, for Windows, see “Canceling Printing” 
    on page 90 or for Macintosh, see “Canceling Printing” on page 132.
    The +Cancel Job button on your printer is the quickest and easiest way to cancel printing.
    For instructions, see “Canceling Printing” on page 185.

    Printing in the PostScript 3 Mode Problems
    The problems listed in this section are those that you may encounter when printing with the 
    PostScript driver. All procedural instructions refer to the PostScript printer driver.
    The printer does not print correctly in the PostScript mode
    The printer does not print
    Cause What to do
    The printer’s emulation mode setting is incorrect. The printer is set to the Auto mode by default, so that it can 
    automatically determine the encoding used in the received 
    print job data and select the appropriate emulation mode. 
    However, there are situations where the printer cannot select 
    the correct emulation mode. In this case, it must be set 
    manually to PS3.
    Set the emulation mode through the SelecType Emulation 
    menu on the printer. See “Emulation Menu” on page 151.
    The printer’s emulation mode setting for the interface 
    that you are using is incorrect.The emulation mode can be set individually for each interface 
    which receives print job data. Set the emulation mode for the 
    interface you are using to PS3. 
    Set the emulation mode through the SelecType Emulation 
    menu on the printer. See “Emulation Menu” on page 151.
    Cause What to do
    The Print to file check box is selected in the Print 
    dialog box (except on Mac OS X).Clear the Print to file check box in the Print dialog box.
    The Save as File check box is selected on the Output 
    Option sheet in the Print dialog box (Mac OS X only).Clear the Save as File check box on the Output Option sheet 
    in the Print dialog box.
    An incorrect printer driver is selected. Make sure that the PostScript printer driver that you are using 
    to print is selected.
    The Emulation menu in the printer’s Control Panel is 
    set to a mode other than Auto or PS3 for the interface 
    that you are using.Change the mode setting to either Auto or PS3.
