Color may change slightly even on the same mod-
el of printer if you use a different version of the
firmware or printer driver, or when you print un-
der different settings or in a different printing en-
vironment. Follow these steps to prepare the printing environment.
1. Use the same version of firmware or printer driver.
2. Specify the same value for all settings items. Banding in different colors occurs
Cause
Corrective Action
The paper feed amount is out of ad-
justment. Adjust the feed amount.
 (See "Adjusting the Feed Amount .") →P.684
Printing does not proceed smoothly
because print jobs are interrupted
during transmission. Exit other applications and cancel other print jobs.
In the printer menu,  Print Length is
specified in  Feed Priority .Selecting

You are printing on paper that curls
easily. Printed colors may appear uneven on the leading edge of paper that is suscepti-
ble to curling. Increase the level of vacuum holding the paper against the Platen
or specify a margin of 20 mm (0.79 in.) or more for the leading edge.
 (See "Adjusting the Vacuum Strength (VacuumStrngth) .") →P.691
Printed colors may be uneven if you
set the Print Quality  too low.Choose a higher level of

driver.
Printing in  Draft or Standard mode is faster and consumes less ink than in
Highest or High modes, but the printing quality is lower.
 (See " Giving Priority to Particular Graphic Elements and Colors for Print-
ing .") →P.56
Color may be uneven between dark
and light image areas. Select 
Unidirectional Printing in the  Advanced Settings of the printer driver. When borderless printing is used,
the edge of the paper is cut during
printing. Thus, ink density may be
uneven at the edges.
Specify No in Auto Cut in the printer driver before printing. In this case, the
paper can be printed without borders on the left and right sides only. Cut the
printed document ejected from the printer, then use scissors to cut away the
edges on the top and bottom.
Choose a higher level of  Print Quality in the Advanced Settings of the printer
driver.
 (See "Giving Priority to Particular Graphic Elements and Colors for Print-
ing .") →P.56
The Printhead is out of alignment. Adjust the Printhead alignment.  (See "Automatic Straightening of Lines and Colors (Auto Head Adj.) .")→P.676
Drying documents stacked on each
other may cause uneven colors. To avoid uneven colors, we recommend drying each sheet separately.
Color density may be uneven if you
use Glossy Paper, art paper, or Coat-
ed Paper. In Advanced Settings of the printer driver, choose 
Highest or High in Print
Quality. The type of paper specified in the
printer driver does not match the
type loaded in the printer.
Load paper of the same type as you have specified in the printer driver.

Cause
Corrective Action
The Ethernet cable
is not connected
correctly to the
printer's Ethernet
port. 1.
Make 
sure  the  printer  is  connected  to  the  network  with  the  correct  Ethernet  cable,  and  then
turn the printer on. For instructions on connecting the cable, refer to the Setup Guide.
2. Make sure the Link indicator is lit.
The Link indicator is green if the printer is connected via 100 Base-TX and orange if connec-
ted via 10Base-T.
If the Link indicator is not lit, check the following points.
• Make sure the hub is on.
• Make sure the end of the Ethernet cable is connected correctly.
Insert the Ethernet cable until it clicks and locks in place.
• Make sure there is no problem with the Ethernet cable.
If there is any problem, replace the Ethernet cable.
• Check the communication mode with the hub.
Although the printer normally detects the hub communication mode and transmission rate
automatically  (in  auto  negotiation  mode),  sometimes  the  hub  settings  cannot  be  detected.
In  this  case,  configure  the  connection  method  manually,  specifying  the  communication mode in use. (See "Configuring the Communication Mode Manually .") →P.776
Cannot print over a TCP/IP network

The NetWare server and
services are not configured
correctly. Check the following points.
1. Make sure the NetWare file server is running.
2. Make 
sure  there  is  enough  free  disk  space  on  the  NetWare  file  server.  Insufficient
disk space may prevent you from processing large print jobs.
3. Start  NWADMIN  or  PCONSOLE  and  confirm  that  the  print  service  is  configured
correctly and the print queue is available.
4. If data transmission to a printer on another subnet fails, deactivate NCP burst mode in
that printer's network protocol settings.
5. If  the  printer  is  used  in  queue  server  mode,  specify  Other/Unknown  as  the  printer
type. Cannot print over AppleTalk or Bonjour networks
Cause
Corrective Action
The AppleTalk protocol is not
enabled on the printer. Activate AppleTalk on the printer.
 (See "Configuring the Printer's AppleTalk Network Settings .") →P.789
The computer you are trying to
print from is not configured cor-
rectly. Make sure the computer's AppleTalk settings are configured correctly.
 (See "Configuring the Destination for AppleTalk Networks  .") →P.790
 (See "Configuring the Destination for Bonjour Network  .") →P.796
The computer and printer are not
on the same network. Due to the nature of Bonjour, you cannot print if the printer is on another network
behind a router. Make sure the computer and printer are on the same network. For
information about network settings, ask your network administrator.Troubleshooting
