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.

The non-printed side of the page is dirty
Memory Problems
Print quality decreased
Insufficient memory for current task
Insufficient memory to print all copies
Cause What to do
Toner may have spilled onto the paper feed path. Clean internal printer components by printing three pages 
with only one character per page.
Cause What to do
The printer cannot print in the required quality level 
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.
If RAM Disk is set to Maximum or Normal on the control panel, you 
can increase the available memory space by changing this 
setting to Off.
Cause What to do

setting to Off.
Cause What to do
The printer does not have sufficient memory to 
collate print jobs.Only one set of copies will be printed. Reduce the contents of 
print jobs, or add more memory. For information on installing 
more memory, see “Memory Module” on page 196.

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.

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.

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.
