Graphics do not print correctly
Cause What to do
The page length and margins may 
be set incorrectly in your 
application. Make sure that you are using the correct 
page length and margin settings in your 
application.
The Paper Size setting may be 
incorrect. Make sure the correct paper size is set in 
the Tray Menu on the control panel.
MP Tray Size setting may be 
incorrect. When loading paper for which the size is 
not specified with Auto setting, specify 
the correct paper size on the MP Tray Size 
setting in the Tray Menu on the control 
panel.
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. Check the color registration and adjust 
the alignment if necessary. See Checking 
Color Registration on page 268 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.

Color Printing Problems
New :C
olor
 product
 only
Cannot print in color
The printout color differs when printed from 
different printers
You may need more memory. Graphics require large amounts of 
memory. Install an appropriate memory 
module. See Memory Module on page 
289.
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 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 Customizing print settings on 
page 67 for Windows, or see Customizing 
print settings on page 151 for Macintosh.

The color looks different from what you see on 
the computer screen
Print Quality Problems
Dots appear every 30 mm on the printout
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, Me, 98, 2000, 
or Server 2003) or ColorSync setting (for 
Macintosh) can improve color matching 
between different devices. For details, 
see Using the predefined settings on 
page 64 for Windows, and Using the 
predefined settings on page 148 for 
Macintosh.
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.
Cause What to do
The photoconductor unit needs to 
be cleaned. Clean the photoconductor unit. See 
Cleaning the photoconductor unit on 
page 347 for details.

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.
Cause What to do
The printer has insufficient memory 
for current task. Add more memory for a permanent 
solution or lower print quality temporarily 
in the printer driver.
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 289.

Problems Using Options
To confirm your options are installed correctly, print a status 
sheet. See Printing a Status Sheet on page 267 for details.
Cause What to do
The paper guides are not set 
correctly. Make sure that the paper guides in all the 
paper cassettes and the MP tray are set 
to the correct paper size positions.
The paper source setting may not 
be correct. Make sure that you have selected the 
correct paper source in your application.
There may be no paper in the 
cassettes. Load paper into the selected paper 
source.
The size of loaded paper differs from 
the control panel or printer driver 
settings. Make sure that the correct paper size and 
paper source are set in the control panel 
or printer driver.
Too many sheets may be loaded in 
the MP tray or paper cassettes. Make sure that you have not tried to load 
too many sheets of paper. For the 
maximum paper capacity for each 
paper source, see MP tray on page 41, 
Standard lower paper cassette on page 
42, and 550-sheet/1100-sheet Paper 
Cassette Unit on page 42.
If paper does not feed from the 
optional paper cassette unit, the 
unit may not be installed properly. For instructions on installing the unit, see 
Optional Paper Cassette Unit on page 
272.
