Misalignment of colors
Graphics do not print correctly
Transparencies are output blank from the MP tray
When there are errors while printing on transparencies, the Check Transparency error 
message is displayed on the LCD panel.
Remove the transparencies from the MP tray. Open and close the front cover. Confirm the 
paper type and size, and then load the correct type of transparencies.
Note:
❏When using transparencies, load them in the MP tray and set the Paper Type setting to 
Transparency in the printer driver.
❏When the Paper Type setting in the printer driver is set to Transparency, do not load any other 
type of paper except transparencies.
Cause What to do
The registration position of each color may 
have shifted while the printer was being 
shipped or moved to a new location.Adjust the color registration alignment. See 
Adjusting Color Registration on page 206 for 
instructions.
Cause What to do
The printer emulation setting in your 
application may be incorrect.Make sure that your application is set for the printer 
emulation you are using. For example, if you are 
using the ESC/Page mode, make sure that your 
application is set to use an ESC/Page printer.
You  may  need  more  memory. Graphics require large amounts of memory. Install an 
appropriate memory module. See Memory Module 
on page 220.

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 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.

Memory Problems
Print quality decreased
Insufficient memory for current task
Insufficient memory to print all copies
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.
