Color misregistration
 

Make sure that the drum unit is installed properly.

Make sure that the belt unit is installed properly.

Make sure that the waste toner box is installed properly.

Perform the auto color registration by using the control panel (see Auto 
Registrationon page 91) or perform the manual color registration by using the

If the color mis-registration is not corrected after registering the color 
manually, take all the toner cartridges out of the drum unit and turn the drum 
unit over, then make sure that four drum unit gears are in the home position. 
The home position of each drum can be identified by matching the number on 
the drum unit gear to the same number on the side of the drum unit as shown 
in the illustration.

Curled or wavy
 

Check the paper type and quality. High temperatures and high humidity will 
cause paper to curl. (See About paperon page 6.)

If you do not use the printer often, the paper may have been in the paper tray 
too long. Turn over the stack of paper in the paper tray. Also, fan the paper 
stack and then rotate the paper 180° in the paper tray.

Follow these steps:
aOpen the back cover.
bPush the gray lever to the right as shown below.

Network problems7
For problems concerning using your printer on a Network, see the Network User’s Guide on the CD-ROM we 
have supplied.
Other problems7
ProblemRecommendation
The printer prints unexpectedly 
or it prints garbage data.
Make sure that the printer cable is not too long. We recommend that you use a 
parallel or USB cable that is no longer than 2 meters (6.5 feet).

Make sure that the printer cable is not damaged or broken.

If you are using an interface-switching device, remove it. Connect your computer 
directly to your printer, and then try again.

Make sure that you have chosen the correct printer driver with ‘Set as Default’.

Make sure that the printer is not connected to the same port that is also 
connected to a storage device or scanner. Take away all other devices and 
connect the port only to the printer.

Turn off the Status Monitor.
The printer cannot print full 
pages of a document. An error 
message Out of Memory is 
appears.
Press Go to print the remaining data in the printer memory. Cancel the print job 
if you want to delete the remaining data in the printer memory. (See 
Buttonson page 70.)

Reduce the complex ity of your document or cut the print resolution.

Add more memory. (See Installing extra memoryon page 95.)
The headers or footers appear 
when the document displays on 
the screen but they do not show 
up when it is printed.
Adjust the top and bottom margins of your document. 
ProblemRecommendation
The printer cannot print.  ‘There 
was an error writing to LPT1: 
for the printer’ error message 
occurs on your computer.
Make sure that the printer cable is not damaged or broken. 

If you have an interface-switching device, make sure that you chose the correct 
printer.
