Printing does not take 
place.Is the IP address selected correctly?
(Windows)If the machine does not have a permanent IP address 
(the machine receives an IP address from a DHCP 
server), printing will not be possible if the IP address 
changes. Print the All Custom Setting List in the 
system settings and check the IP address of the 
machine. If the IP address has changed, change the 
port setting in the printer driver. 
➞System Settings > List Print (User) > All Custom 
Setting List
☞Software Setup Guide
If the IP address changes frequently, it is recommended 
that a permanent IP address be assigned to the machine.

Are you using a printer port created 
using Standard TCP/IP Port?
(Windows 2000/XP/Server 2003/Vista/
Server 2008)When a port created with Standard TCP/IP Port in 
Windows is used and the [SNMP Status Enabled] 
checkbox is  , it may not be possible to print correctly. 
Change the [SNMP Status Enabled] checkbox to  .

Is Connect via set to [Ethernet] for 
AppleTalk?
(Mac OS 9.0-9.2.2)
Open [AppleTalk] from the [Control Panels] and make 
sure that [Ethernet] is selected in the Connect via 
menu. Printing is not possible if [Ethernet] is not selected.
Is your computer in an unstable state? Printing is sometimes not possible when you run 
multiple applications at once or there is insufficient 
memory or hard drive space. Restart your computer.
Is the machine specified correctly in the 
software application that you are using 
for printing?Make sure that the printer driver of the machine is 
selected in the Print window of the application.
If the printer driver does not appear in the list of 
available printer drivers, it may not be installed correctly. 
Remove the printer driver and then install it once again.

operating normally?Make sure that the routers and other network 
connection devices are operating correctly. If a device is 
not powered on or is in an error state, see the manual of 
the device to correct the problem.
Is the I/O timeout setting too short?
If the I/O timeout setting is too short, errors may occur 
while writing to the printer. Ask the administrator of the 
machine to configure an appropriate time in I/O Timeout.

Printing does not take 
place.Was  a  Notice Page  printed? A Notice Page will be printed to indicate the cause of the 
problem if a print job cannot be performed as specified 
and the cause is not shown in the display. Read the 
printed page and take appropriate action.
For example, a notice page will be printed in the 
following situations.
 The print job is too large to fit in memory.
 A function that has been prohibited by the 
administrator is specified.
By factory default, Notice Pages are not printed.
Have functions been disabled by the 
administrator?When user authentication is enabled, the functions that 
you can use may be restricted in your user settings.

you can use may be restricted in your user settings. 
Check with your administrator.
Two-sided printing 
does not take place.Does the paper type setting of the 
selected tray specify a type of paper that 
cannot be used for two-sided printing?Check Tray Settings in the system settings.
 If the [Disable Duplex] checkbox is selected  , 
two-sided printing using that tray will not be possible. 
Change the paper type setting to a type that can be 
used for two-sided printing.

The image is grainy. Are the printer driver settings 
appropriate for the print job? When selecting print settings, you can set the print 
mode to [Normal], [High Qua
lity], or [Fine]. When you 
need a very clear image, select  [Fine]. (The [Fine] mode 
cannot be selected when using the PCL5c printer 
driver.)
Windows: The resolution setting is selected in the [Advanced] 
tab of the printer driver properties window.
Macintosh: Select the resolution in the [Advanced] menu of the 
print window. (In Mac OS v10.5, select the resolution 
on the [Color] menu in the print window.)
The image is too light 
or too dark. Does the image (particularly a photo) 
need correction?
(Windows) Brightness and contrast can be corrected by performing 
[Color Adjustment] on the [C
olor] tab of the printer 
driver. These settings can be used for simple 
corrections when you do not have image editing 
software installed on your computer.
Colors are off. Did you perform Registration 
Adjustment? Ask your administrator to perform Registration 
Adjustment.
➞ System Settings (Administrator) > Device Control >

If the color tones are off, perform Auto Color 
Calibration. (If the colors are still off after calibration, 
repeating calibration may improve the results.) ➞ System Settings (Administrator) > Printer Settings >

Text and lines are faint 
and difficult to see. Was color data printed in black and 
white?
(Windows) When color text and lines are printed in black and white, 
they may become faint and difficult to see. To have 
color text or lines (areas) that are faint converted to 
black, select [Text To Black] or [Vector To Black] on the 
[Color] tab of the printer driver. (Raster data such as 
bitmap images cannot be adjusted.)

Part of the image is 
cut off.Does the paper size specified by the job 
match the size of paper loaded in the 
tray?Make sure that the paper size setting matches the size 
of paper loaded in the tray.
The paper size setting is selected as follows:
Windows:
On the [Paper] tab of the printer driver.
If [Fit to Paper Size] is selected, check the loaded 
paper and the paper size setting.
Macintosh:
In the [Page Setup] menu.
Is the print orientation setting (portrait or 
landscape) correct?Set the print orientation to match the image.
The print orientation is selected as follows:
Windows: On the [Main] tab of the printer driver.
Macintosh: In the [Page Setup] menu.
Are the margins set correctly in the 
layout settings of the application?If the edge of the image extends outside the printable 
area of the machine, the edge will be cut off. Select an 
appropriate paper size and margins in the layout 
settings of the application.
The image is upside 
down.Are you using a type of paper (tab 
paper, punch paper, etc.) that can only 
be loaded in a fixed orientation?When the image size and paper size are the same but 
the orientations are different, the orientation of the 
image is automatically rotated to match the paper. 
However, when the paper can only be loaded in a fixed 
orientation, this may result in the image being printed 
upside down. In this event, rotate the image 180 
degrees before printing.
The 180 degree rotation setting is selected as follows:
Windows:
On the [Main] tab of the printer driver.
Macintosh (OS X v10.3.9 to 10.5.1):
On the [Page Setup] menu. (Landscape orientation 
only.)
(In Mac OS 9.0 to 9.2.2, in the [PostScript Options] 
menu of the [Page Setup] menu.)
Is the correct binding position selected 
for two-sided printing?When two-sided printing is performed, every other page 
is printed upside down when tablet binding is selected 
for the binding position. Be sure to set the appropriate 
binding position.
The binding position is selected as follows:
Windows:
On the [Main] tab of the printer driver.
Macintosh:
In the [Layout] menu of the print window. (In Mac OS 
9.0 to 9.2.2, in [Output/Document Style].)

Many nonsense 
characters are printed.Is your computer or the machine in an 
unstable state?If little free space remains in the memory or hard drive of 
your computer, or many jobs have been spooled on the 
machine and it has little free memory remaining, printed 
text may turn into nonsense characters. In this situation, 
cancel printing, restart your computer and the machine, 
and try printing again.
To cancel printing
Windows:
Double-click the printer icon that appears at the lower 
right of the task bar and click Cancel All Documents 
(or Purge Print Documents) in the [Printer] menu.
Macintosh:
Double-click the name of the machine in the printer 
list, select the job that you wish to delete, and delete 
it. (In Mac OS 9.0 to 9.2.2, double-click the printer 
icon on the desktop, select the print job that you wish 
to delete, and delete it.)
At the machine:
Press the [JOB STATUS] key on the operation panel, 
touch the [Print Job] tab to change the screen, touch 
the key of the print job that you wish to delete, and 
touch the [Stop/Delete] key. A message appears to 
confirm the cancelation. Touch the [Yes] key.
If nonsense characters are still printed after restarting, 
ask your administrator to lengthen the timeout setting of 
I/O Timeout in the system settings (administrator).

Interface Settings > I/O Timeout
If nonsense characters are still printed after taking the 
above measures, remove and then reinstall the printer
